Tornado Tracks in Tuscaloosa, Alabama

Deadly tornadoes raked across Alabama on April 27, 2011, killing as many as 210 people as of April 29. The hardest-hit community was Tuscaloosa. The top image, acquired on April 28 by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, shows three tornado tracks through and around the city. The lower image, from April 12, shows the area before the storm.
The tracks are pale brown trails where green trees and plants have been uprooted, leaving disturbed ground. Though faint, the center track runs from southwest of Tuscaloosa, through the gray city, and extends northeast towards Birmingham. Two other tracks run parallel to the center track. The northernmost track lies in an area where the National Weather Service reported a tornado, but no tornado was reported in the vicinity of the more visible southern track. In the southern region, strong winds were reported.
The tornadoes were part of a larger weather pattern that produced more than 150 tornadoes across six states, according to the National Weather Service. The death toll reached 300 on April 29, making the outbreak the deadliest in the United States since 1974.

Bay shaping up to host season’s first ‘low’

A low-pressure is now expected to pop up over the Bay of Bengal by Sunday as a persisting upper air circulation descends to lower levels and matures.
In the run-up to this likely denouement, the Andaman and Nicobar Islands are expected get buffeted by rains or thundershowers over the weekend, India Meteorological Department (IMD) said on Friday.

The seas have warmed up to well above 30 deg Celsius, which is more than enough to sustain the brewing ‘low.’
This would also help steer the flows in the Bay to being more easterly to southeasterly, after having seen the back of a harmful ‘ridge’ or high-pressure region that has been pushed away.
The ‘low’ has been delayed this year from mid-April, which is normally the time around which the Bay gets its act together.
Meanwhile, peninsular India and adjoining east India, constituting two-thirds of the landmass in south, central and east-central regions, has witnessed surplus summer rains for almost two months between March 1 and April 27.

Rainfall deficiencies have been confined to extreme west and northwest, according to an update provided by the IMD.
The Gujarat and Sourashtra region, Madhya Pradesh, Rajasthan, Punjab, Haryana and Delhi, Himachal Pradesh and Uttar Pradesh totted up varying deficiencies.
Jammu and Kashmir was the only Met subdivision to record a normal (+5 per cent) rainfall in the northwest while only Gujarat was totally devoid of any rainfall.
Among the Met subdivisions which surprised on the upside with surplus rainfall thus far during the season are Telengana (+43 per cent); Rayalaseema (+28 per cent); Vidarbha (+75 per cent); Chhattisgarh (+117 per cent); Bihar (+36 per cent); Gangetic West Bengal (+101 per cent); north interior Karnataka (+67 per cent); and south interior Karnataka (+103 per cent).

The larger Maharashtra, Andhra Pradesh, Orissa and Jharkhand states also found themselves falling in the ‘normal’ category.
One significant fall-out of the rainfall pattern has been the less than normal cooling of these regions and total absence of heat waves that normally take a toll on human and animal lives.
Some weather watchers have also tended to view with this caution in terms of the likely impact on the impending of the monsoon that drives essentially on land-sea surface temperature contrasts.
Global weather models are, however, of the view that sustained heating of the land surface has already started from northwest India and would filter into central, east-central and parts of peninsular India from the coming week onwards.

Meanwhile, fairly widespread overnight rain or thundershowers has been reported from Andaman and Nicobar Islands overnight on Friday.
It was scattered over sub-Himalayan West Bengal, Sikkim, Meghalaya and Tripura and isolated over Jammu and Kashmir, east Uttar Pradesh, Orissa, south interior Karnataka and Tamil Nadu.
On Thursday, maximum temperatures were above normal by 2 to 4 deg Celsius over some parts of Punjab, east Rajasthan, northwest Madhya Pradesh.
But they continued to be below normal by 2 to 4 deg Celsius over Chhattisgarh, Jharkhand, Tripura and Orissa.

The highest maximum temperature of 44.0 deg Celsius was recorded at Churu (Rajasthan), Jalgaon (Maharashtra) and Khargone (Madhya Pradesh) on Thursday.
Satellite pictures early on Friday morning showed the presence of convective (rain-bearing) clouds over parts of Jammu and Kashmir, Bihar, sub-Himalayan West Bengal, Sikkim, Assam, Kerala, Tamil Nadu, south and east-central Bay of Bengal and the Andaman Sea.
The western disturbance over north Pakistan and adjoining Jammu and Kashmir now lies over Jammu and Kashmir. It would affect western Himalayan region and adjoining plains of northwest India until Monday.

Heating of land apace in northwest India

A forecast outlook from India Meteorological Department (IMD) indicates that the summer heating of extreme northwest India has started in right earnest.
Arrival of a spoilsport western disturbance has been factored in, but its influence would not extend beyond Jammu and Kashmir and Himachal Pradesh. Mainly dry weather is expected to prevail over the plains of northwest and adjoining west and central India.
The westerly system would be able to do no more than cap the heating trend in the northwest, according to the outlook.
Strong surface winds would prevail over Gujarat, Rajasthan and the Indo-Gangetic plains until Friday. No significant change in temperatures is seen over parts of the plains of northwest India and adjoining central and west India until Friday, the IMD said.
Meanwhile, maximum temperatures recorded on Tuesday ranged between 40.0 deg Celsius to 44.0 deg Celsius at many parts of Rajasthan, west Madhya Pradesh, north Gujarat and Vidarbha.
Global models had indicated earlier that the core heating would cross the northwest border into the western parts of India from this week. This is where the ‘heat low’, a peculiar phenomenon triggered by sustained heating of the land surface develops locally.
This in turn leads to the creation of an elongated area of lower pressure extending from the West Asia desert across Pakistan and into northwest India. This is unlike the usual pattern when heating of the land assumes the sinking motion of air and therefore higher pressure.
The ‘heat low’ is a crucial cog in the wheel of the monsoon system, helping draw, as it would, moisture-laden southwesterly winds from the Arabian Sea and the Bay of Bengal.
Even as the northwest is heating up, the IMD said maximum temperatures were below normal by 2 to 6 deg Celsius over Gangetic plains and Tamil Nadu on Wednesday.
They were near normal over rest of the country except parts of Assam, Meghalaya, Arunachal Pradesh and interior Maharashtra where they are above normal by 2 to 3 deg Celsius. The highest maximum temperature of 45.2 deg Celsius was recorded at Ganganagar in Rajasthan.
During the day on Tuesday, scattered rain or thundershowers occurred over Tamil Nadu and Jharkhand and isolated over east Uttar Pradesh, sub-Himalayan West Bengal, Sikkim and Kerala.
Satellite imagery early on Wednesday morning showed the presence of convective (rain-driving) clouds over parts of south and east-central Bay of Bengal, Assam, Nagaland, Manipur and southeast Arabian Sea.
The IMD traced a trough extending from west Rajasthan to southwest Bay of Bengal across interior Maharashtra, interior Karnataka and Tamil Nadu with embedded upper air cyclonic circulations over west Madhya Pradesh and southwest Bay of Bengal.
Another trough lay extended from an upper air cyclonic circulation over west Madhya Pradesh and ‘telescoped’ into a counterpart circulation over Gangetic west Bengal. In the process, the trough passed over east Madhya Pradesh, north Chhattisgarh and Jharkhand.
A weather warning said that isolated thunder squalls would occur over Jharkhand, Orissa, West Bengal, Sikkim and the Northeastern States until Friday.
A short-term outlook said that fairly widespread rain or thundershowers would occur over Andaman and Nicobar Islands and Lakshadweep until Friday. Scattered rain or thundershowers may break out occur over south and coastal Karnataka, Kerala and Tamil Nadu during this period.
Scattered rain or thundershowers would unfold over the Northeastern States, West Bengal, Sikkim, Jharkhand, Orissa and Chhattisgarh. It may relent later over Jharkhand and Chhattisgarh from Friday.
Isolated rain or thundershowers are likely over Jammu and Kashmir and Himachal Pradesh from Friday.
An extended outlook until Sunday said that scattered rain or thundershowers would occur over northeast and adjoining east and south peninsular India.

Who Needs a Weatherman? People-Powered Meteorology !! ...

Who Needs a Weatherman? People-Powered Meteorology !!

Weather conditions are most often defined in terms of temperature, humidity and wind factor. New iPhone application Weddar [iTunes link] challenges this notion with a system that gives users the ability to submit reports based on how the weather feels.
“We wanted a very simplistic approach for all people,” explains co-creator Ricardo Fonseca, “so that they could express their feelings about how they feel the weather.”
Simplistic it is. Weddar presents the user with nine different weather report selections that take the form of color-coded clouds — think Perfect, Hot, Good or Hell — and four optional modifiers so users can specify whether it’s cloudy, rainy, windy or snowy.
Reports are added to the map according to the user’s location, and then visible to other app users in the map view. That’s pretty much all there is to it, though users can also request weather reports by pressing on a place on the map for a second. That action will produce a white cloud on the map and will signal other users to add their reports.

Weddar’s greatest quality is that it’s hyper-local. Because weather reports are tied to a user’s location, they reflect the current feel of an exact locale and offer users more data — as fuzzy as it may be — on the area’s conditions. This means that Weddar can account for microclimates far better than the local TV weatherman.
Of course, that depends on whether anyone is actually using Weddar. The application, released Monday, is seeing some traction, according to Fonseca. He won’t share specific numbers, but he does say that users in 63 different countries have submitted weather reports via Weddar. The app has reached the number two position on the Free Apps chart in Portugal, where Weddar parent-company 96HP is based.
The startup won’t be putting any weathermen (or weathergirls) out of business anytime soon. Sometimes we need a real temperature reading and a bit more to go on than, say, “Fresh”. But the app’s crowdsourced and mobile nature could give it an edge if the idea takes off with enough iPhone users.
Weddar is currently self-funded. The startup plans to introduce new features such as photo uploads in the months ahead.

Westerly system may stray into North-West by Thursday

India Meteorological Department (IMD) has said that a western disturbance would stray into northwest India from Thursday onwards.
But the system is not seen drastically changing the weather parameters over the region, which would continue to witness mainly dry weather.
Isolated rain or thundershowers would occur over Jammu and Kashmir from Friday onwards.
Strong surface winds are expected to prevail over Gujarat, Rajasthan and the Indo-Gangetic plains during this period.
Meanwhile on Tuesday, an upper air cyclonic circulation persisted over northwest Madhya Pradesh and neighbourhood.
This, in turn, triggered the formation of a southward-bound and weather-making trough that passed through Marathwada, interior Karnataka and Tamil Nadu.
The trough then “telescoped” into a counterpart upper air cyclonic circulation over southwest Bay of Bengal.
A third upper air cyclonic circulation was on view over Gangetic West Bengal, presiding over local weather.
A weather warning from IMD said that isolated thunder squalls would break out over Bihar, Jharkhand, Orissa, West Bengal, Sikkim and the Northeastern States until Thursday.
The 24 hours ending Tuesday morning saw fairly widespread rain or thundershowers break out over Gangetic West Bengal, Orissa, Meghalaya, Kerala and Tamil Nadu.
It was scattered over sub-Himalayan West Bengal, Sikkim, east Uttar Pradesh, Bihar, Chhattisgarh, south Karnataka and the Andaman and Nicobar Islands.
It was isolated over Jharkhand, Arunachal Pradesh, Assam, Telangana and north coastal Andhra Pradesh.
Satellite imagery in the afternoon indicated the presence of convective (rain-triggering) clouds over parts of south and central Bay of Bengal, southeast Arabian Sea and the Comorin area.
A short-term outlook valid until Friday said that fairly widespread rain or thundershowers would unfold over coastal Karnataka, Kerala, Tamil Nadu and Andaman and Nicobar Islands.
However, the rainfall over Tamil Nadu would weaken in intensity from Wednesday as the clouding spreads out in an east-to-northeast direction into the sea.
Scattered rain or thundershowers is likely over Lakshadweep and south interior Karnataka.

If DMK loses polls, blame their Renewable Energy policy in Tamil Nadu

Tamil Nadu had finally voted on April 13th though counting is on May 13th. In what is seen as an extremely tight contest with tempers rising high during the campaign, among the major poll issues was the acute power shortage faced by the state. With voting over, Tamil Nadu is set to face longer power outages following a decision by the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) to increase the load shedding period from two hours to three hours every day.

Chennai faces an-hour-long power cut while other parts of the state it will be not less than 3 hours a day. The TANGEDCO decision comes in the face of an increasing power deficit in the State, combined with rising deficits in other States.

‘Enhanced rain' from May to July, says Korean forecaster

The Busan, South Korea-based APEC Climate Centre has said in updated forecast on Monday that India might witness ‘enhanced rains' during May-June-July.
This was slightly at variance with some other global models that saw a weaker start to the southwest monsoon, only to be followed by a burst mid-season till the end.

In fact, the APEC centre saw some deficiencies in July, especially over central and east-central India and the northwest. The outlook for August and September was not available on Monday.
The forecast said that the east Asian coast and Indonesia will receive less rainfall than normal. On the other hand, enhanced precipitation is expected over Indochina and the Philippines, apart from India.
Meanwhile, an India Meteorological Department (IMD) outlook on Monday evening said that the scattered rain or thundershowers over east, northeast and south peninsular India would continue until the month-end.

Mainly dry weather would prevail over northwest and adjoining west and central India during this period, with western disturbances staying away.
A satellite picture in the afternoon indicated the presence of convective (rain-driving) clouds over extreme peninsular India, south Arabian Sea, the Comorin area and south and central Bay of Bengal and the Andaman Sea.
A short-term outlook valid until Thursday said that the fairly widespread rain or thundershowers would sustain over Kerala, coastal Karnataka, and Tamil Nadu.
It would be scattered over Lakshadweep, interior Karnataka and Andaman and Nicobar Islands while being isolated over coastal Andhra Pradesh.

As has been the case, the causative system for this weather would be a trough that originates from upcountry and extends down to the south.
On Monday, the IMD located this weather-making trough extending from a cyclonic circulation over southeast Rajasthan and adjoining northwest Madhya Pradesh and running down through Madhya Pradesh and Karnataka.
It consummated in another upper air cyclonic circulation over south Tamil Nadu.
Global models as well as the IMD expect this circulation to emerge into the adjoining Bay of Bengal and drive east-northeast towards central Bay. Towards the east, fairly widespread rain or thundershowers are expected unfold over east and northeast India until Tuesday.

On Sunday, the highest maximum temperature of 43.5 deg Celsius was recorded at Deesa in Gujarat. A rise in maximum temperatures by 1 to 2 deg Celsius has been indicated for northwest and adjoining central India.
A weather warning said that isolated thunder squalls would occur over Bihar, Jharkhand, Orissa, West Bengal, Sikkim and the Northeastern States until Tuesday. The rollout of the rough weather here would be overseen by two upper air circulations over Assam and neighbourhood and southeast Uttar Pradesh and neighbourhood, the IMD said.

As La Nina Tapers off, How will the Monsoons behave?

The IMD finally released their monsoon forecast, after dithering for some time.  Speaking to CNBC-TV18's Karan Thapar, Ajit Tyagi, Director General of the Indian Meteorological Department (IMD), said this year the forecast in quantitative terms is of 98%, which falls in the normal category. 
"We are confident within the model areas of plus/minus 5%. In extreme cases to be below normal category, which is between 90 and 96%—to be preciously the 93%, if we minus 5% from the 98%," he said raising hopes of higher farm output that could help the government tame high food prices."

As per the latest data from the Bureau of Meteorology, Australia, the La Niña, which brought above normal rainfall to India last year, has run its course with the central Pacific returning to El Niño-Southern Oscillation (ENSO)  neutral conditions as reflected by the Nino 3.4 Index being 0.4 C deg. Since January this year, due to the La Niña effect, daytime maxima have been too low for ‘monsoon comfort’ since sustained heating of the northwest region is crucial to set up the keenly watched ‘heat low’ to build. The heat low builds due to sustained heating of northwest India, adjoining Pakistan and the Arabia desert.  

It is these conditions what posed a dilemma for IMD in their forecast of the monsoon and they dithered finalizing it until it became clear that we have returned to ENSO neutral conditions by mid-April, which can reduce rainfall. in the country. We can now hope that daytime maxima returns to normal fully in May to establish the south-westerly monsoon wind regime before heavy monsoon rains start over western India. Unlike other low-pressure areas, the ‘heat low’ is topped up by clear, cloud-free skies due to special reasons associated with the geography.

Southern parts of Western Ghats is the origin for ‘matti' bananas ...

southern parts of Western Ghats is the origin for ‘matti' bananas

The Western Ghats is home to many endangered species of flora. Continuous research in Megamalai and forest surrounding Mangaladevi Kannagi Temple in Theni district has proved that southern parts of Western Ghats is the origin for ‘matti' bananas ( Musa Accuminata), a variety predominantly grown only in Kanyakumari district in the State.
Researchers believe that this cultivable variety could have been evolved from continuous domestication of the ‘wild matti' present in the southern Western Ghats, said V. Ganesan, District Forest Officer.
Hill banana is a popular fruit in the country, known for its nutritional value. The origin of this species had been traced to the Indo-Malayan belt. Cultivatable banana evolved from two wild species — ‘ Musa acuminata' and ‘ Musa Balbisiana.' Though various varieties such as ‘Poovan,' ‘Rasthali,' red banana, Hill banana, Nendran, Monthan, dwarf Cavendish, Ney poovan and ‘matti' are famous in various part of the State, knowledge about wild species was very limited, Mr. Ganesan said.
A related genus of ‘kalvazhai' ( Ensete Superbum), known to occur on Western Ghats, was found in Mangaladevi Kannagi Temple forest area recently.
Plant exploration and expeditions conducted by the forest officer in the rainforests abutting private estates in Megamalai, one of the biodiversity hotspots in Western Ghats, resulted in discovery of the wild banana, popularly known as ‘Channa vazhai.' After in-depth study of morphological characters of leaves, pseudo stem, flowers and fruits, the variety resembled to that of cultivated ones.
Similar study conducted on various parts of Western Ghats between Anamalai and Kanyakumari in the past decade confirmed the origin of ‘Matti' variety of the wild banana, Mr. Ganesan said.

Disturbed weather to sustain over east India, south peninsula

Disturbed weather continued to engulf parts of northwest India, east and northeast India, the eastern seaboard and adjoining peninsular India overnight on Monday.
An India Meteorological Department (IMD) update said that widespread rain or snowfall was recorded in Jammu and Kashmir and Himachal Pradesh while it was scattered over Uttarakhand.


Fairly widespread rainfall occurred over Punjab, Haryana, Chandigarh and Delhi during this period.
But it was isolated over Rajasthan, Meghalaya, east Madhya Pradesh, Orissa, Maharashtra, coastal Andhra Pradesh, Karnataka, Kerala, Lakshadweep, Tamil Nadu and Andaman and Nicobar Islands.
Satellite imagery on Monday afternoon indicated that the unstable weather would continue to hold over many of these regions on Tuesday as well.
Convective (rain-bearing) clouds had gathered over Jammu and Kashmir, Himachal Pradesh, Bihar, Jharkhand, Sub-Himalayan West Bengal, Sikkim, Assam, Meghalaya, Kerala, Tamil Nadu, the Comorin area, south Bay of Bengal and south Arabian Sea.


A weather warning issued by the IMD said that isolated thunder squalls would occur over east Uttar Pradesh, Bihar, Jharkhand, West Bengal and Sikkim on Tuesday.
Meanwhile, the weather-maker western disturbance has on Monday crossed in fully over Jammu and Kashmir.
An evening bulletin said that the system and the retinue are moving eastwards. It would affect western Himalayan region and adjoining plains of northwest India on Tuesday.
The induced upper air cyclonic circulation over Punjab is moving eastwards while a counterpart circulation persisted over north Madhya Pradesh and adjoining south Uttar Pradesh.
It is from here that a ‘trough couple' – one reaching all the way down to south Tamil Nadu across Vidarbha and Andhra Pradesh and the other east-southeast to Nagaland.


The spike in maximum temperature to within touching distance from the 45 deg Celsius-mark provided a pleasant surprise overnight on Monday.
The IMD said that Sunday's highest maximum of 44.1 deg Celsius was recorded at Umaria in Madhya Pradesh during the 24 hours ending in the morning.

On 15-Apr.. highest maximum temperature of 41.8 C was recorded at Idar (Gujarat)
Induced upper air cyclonic circulation over central parts of Rajasthan persists in lower levels.
A ‘low' in the Bay around this time is a typical pre-monsoon season feature ... and is due around this time..
A wet Madden-Julian Oscillation wave is seen transiting southwest Indian Ocean below Sri Lankan latitude around 29-Apr.
On 15-Apr, Karnataka ... Pre-monsoon rains, lightning strikes claim 19 lives in Karna ...
5pm, Widespread T.showers over Chatisgarh and Orissa .. ..
5pm, Heavy T.showers all over W.ghats of Maharastra ... and Massive T.showers breaking over desert W,N Rajasthan ..

Weak pre-monsoon ‘low' indicated in Bay of Bengal

There is an emerging consensus among some global forecast models on the possibility of a weak low-pressure area building in the south and adjoining central Bay of Bengal over the next five to seven-day period. A ‘low' in the Bay around this time is a typical pre-monsoon season feature, and will help steer the flows to converge during the rest of the season.


Last year the Bay had to wait for the third week of April for the ‘low' to shape up, while the just year before was fortunate witness the same as early as April 12.
It had gone to become a tropical cyclone, but no such forecast was indicated for the impending ‘low' in the Bay.
A favourable phase of the periodical Madden-Julian Oscillation (MJO) wave is seen transiting southwest Indian Ocean below Sri Lankan latitude and towards Indonesia around April 20.


At least two major MJO trackers suggested that the impact of the upper-level wave, which is known to trigger weather over the region it passes, would last until the month-end.
No consensus outlook was available as to the exact location for the formation of the ‘low,' but the vast seas between Sri Lanka and the Andaman and Nicobar Islands suggested themselves as the most likely area.
Meanwhile, the 24 hours ending Friday morning saw widespread rainfall being reported from Assam, Nagaland, Manipur, Mizoram, Tripura, sub-Himalayan West Bengal, Sikkim, Karnataka and Lakshadweep.
Peaking pre-monsoon activity over land also saw fairly widespread during this period over Bihar, Gangetic West Bengal, Chhattisgarh, Vidarbha and Kerala, an India Meteorological Department (IMD) update said in the evening.
It was isolated over Jharkhand, Orissa, east Madhya Pradesh, Uttar Pradesh, Marathawada and Tamil Nadu.
Isolated rain or snowfall was also reported from Himachal Pradesh and Uttarakhand. 
According to IMD models .. Entire S. peninsula will come under Showers from 19-Apr till 23-Apr and beyond. !! ..
A weak UAC can be seen over S.Bay along 5th parallel .. It'll affect Srilanka, S. Tamilnadu for next 48 hrs..

Unstable weather to persist over large parts of country

With a fresh western disturbance expected to cross into the western Himalayas and the adjoining plains of northwest India, regional weather is expected to remain unstable during the weekend and into the next.
The rumble would also be heard in distant east and northeast India as well as the south, as offspring troughs and associated circulations dig in over these regions.
An India Meteorological Department (IMD) update on Thursday evening said that the fresh westerly would start affecting the western Himalayas and adjoining plains from Friday onwards.
An upper air cyclonic circulation in the lower levels over Bihar and neighbourhood persisted from overnight as did a counterpart circulation over Nagaland.
A weather-making trough lay extended from southwest Madhya Pradesh to coastal Kerala across Maharashtra and Karnataka.
A weather warning valid until Saturday said that isolated thunder squalls would occur over Bihar, Jharkhand, Chhattisgarh, Orissa, West Bengal and Sikkim.
Global weather models also indicated that the unstable weather (as distinct from stable or clear) would spill over into the next week.
The 24 hours ending on Thursday morning said that fairly widespread rain or snowfall was reported from Himachal Pradesh while it was scattered over Uttarakhand and isolated over Jammu and Kashmir.
Fairly widespread rainfall also broke out over Assam, Meghalaya and Kerala; scattered over Uttar Pradesh, Karnataka, Lakshadweep, Orissa, sub-Himalayan West Bengal, Sikkim and Chhattisgarh.
It was isolated over Madhya Pradesh, Maharashtra, Andhra Pradesh, Jharkhand, Bihar, Gangetic West Bengal, Tamil Nadu and Andaman and Nicobar Island.
Satellite pictures on Thursday afternoon revealed the presence of convective (rain-bearing) clouds over parts of sub-Himalayan West Bengal, Sikkim, the Northeastern States, south interior Karnataka and southeast Arabian Sea.
A short-term IMD outlook valid until Sunday said that widespread to fairly widespread rain, thunderstorms and dust storms would be unleashed over most of these areas in varying intensities.
An extended forecast valid until Tuesday said that scattered rain or snow would occur over the western Himalayan region.
