Late December and early January Cyclones: Will it happen during 2011 or 2012

Many models predict cyclone to come close to Tamil Nadu coast during last week of December 2011. Off late GFS is not so accurate in its forecast.

I have compiled some of the cyclones which have formed in December and have crossed Tamil Nadu coast since 1950.



Almost all the cyclones have formed in the first week of December. Only one cyclone ie 1964 Rameshwaram Cyclone which crossed the Tamil Nadu coast and the 2000 Sri Lanka cyclone have formed around the Christmas period. And the 1964 cyclone was the only super cyclone to hit Tamil Nadu in recent memory. The Sri Lanka cyclone was the first cyclone over Sri Lanka with winds of at least hurricane strength since 1978.

GFS Boxing day Future Cyclone - 26th December

GFS New Year Future Cyclone - 02nd Janauary

Widespread rain over TN, Kerala

A weather warning valid for Saturday and Sunday said that isolated heavy rainfall would occur over south Tamil Nadu and Kerala.

Widespread rainfall has occurred over Tamil Nadu and Kerala during the 24 hours ending Friday morning ahead of an easterly wave action expected to be triggered along the Tamil Nadu coast from Saturday.

All the same, the freak weather masterminded by the Arabian Sea along the West Coast persisted, with fairly widespread rain being reported over as far as Himachal Pradesh and Uttarakhand.

It was scattered over Madhya Pradesh, Vidarbha, South Andhra Pradesh, Coastal Karnataka and Jammu and Kashmir, an update from India Meteorological Department (IMD) said.

MERCURY DOWN

Meanwhile, minimum temperatures have fallen by 2 to 3 deg Celsius over Rajasthan, Punjab, Haryana, Delhi, Uttarakhand, Himachal Pradesh, Uttar Pradesh and East Madhya Pradesh during past 24 hours with some of the clouds clearing off.

However, they still continue to remain above normal by 4 to 6 deg Celsius over these regions, the IMD noted.

On Friday afternoon, Insat cloud imagery showed convective (rain-bearing) clouds driven down south to over parts of extreme South Peninsula, South Bay of Bengal, South Andaman Sea and East-central and Southeast Arabian Sea.

The upper air cyclonic circulation over East-central Arabian Sea persisted, and so did the trough from this system, though truncated and extending up to Gujarat only on Friday. But, the other weather-making trough embedded in the seasonal westerlies across the North-west border had checked in over North-east Rajasthan and neighbourhood.

WEATHER WARNING

A weather warning valid for Saturday and Sunday said that isolated heavy rainfall would occur over South Tamil Nadu and Kerala.

Forecast until Monday spoke about the possibility of fairly widespread rain or thundershowers for Kerala, Lakshadweep, Tamil Nadu and Andaman and Nicobar Islands.

It will be scattered or in the form of thundershowers over South Coastal Andhra Pradesh, Rayalaseema, Coastal and South Interior Karnataka, Konkan and Goa.

Minimum temperature is expected to fall further by 2 to 4 deg Celsius over many parts of North-west, Central and East India during the next week as colder north-westerlies begin to fill the plains.

Extended forecast until Wednesday said that fairly widespread rains would fall over South Peninsular India while being scattered over Gujarat and adjoining Rajasthan.

LA NINA OUTLOOK

Meanwhile, better model consensus is becoming evident over the tenure of the persisting La Nina event in the East Equatorial Pacific.

The strong La Nina conditions that boosted the Indian monsoon this year will continue at least into early next year, an update from the Australian Bureau of Meteorology (BoM) said. Earlier, a group of Japanese scientists at the Tokyo-based Regional Institute for Global Change had said that the La Nina might last for entire 2011 and even into 2012.

On Friday, the Climate Prediction Centre (CPC) of the US National Weather Services said that there is a 25 per cent chance that the La Nina would last into August-September-October 2011, well after the south-west monsoon for the year has ended.

‘Neutral' (neither La Nina nor monsoon-killer El Nino) conditions have been given a 50 per cent chance of sustaining while El Nino itself is being given only 25 per cent, according to the CPC outlook.

Even ‘neutral' conditions are enough to favour the cause of a trouble-free south-west monsoon for India, according to some experts.

Under its influence, rain/thundershower would occur at most places with isolated heavy to very heavy falls over north coastal Tamil Nadu, Puducherry and south coastal Andhra Pradesh during next 24 hours and thereafter the intensity would increase with heavy to very heavy falls at a few places and isolated extremely heavy falls (≥25 cm) over north Tamil Nadu, Puducherry, south coastal Andhra Pradesh and Rayalaseema. Fairly widespread rain would occur over south coastal Tamilnadu during next 48 hours with isolated heavy to very heavy falls.

Gale winds speed reaching 60-70 kmph gusting to 80 kmph would prevail along and off North Tamil Nadu, Puducherry and south Andhra Pradesh coasts from to night It may increase upto 120-130 kmph gusting to 140 kmph at the time of landfall. Sea conditions will be very rough to high, along and off these coasts becoming phenomenal at the time of landfall. 

Storm surge of about 1-2 metres above the astronomical tide may inundate the low lying areas of Nellore & Prakasam districts of Andhra pradesh and Tiruvallur, Chennai & Kanchipuram districts of Tamilnadu at the time of landfall.

Damage expected: 

Extensive damage to thatched roofs and huts. Minor damage to power and communication lines due to uprooting of large avenue trees. Flooding of escape routes.

Breaking: Cyclone Jal to Hit Tamil Nadu, Andhra and Sri Lanka

Jal  is expected to hit southeast Chennai and Nellore, Thiruvallur, Puducherry and Kancheepuram. Tropical Cyclone Jal will approach the southeastern coast of India  as a Category 1 cyclone. An inundating storm surge will also pose a serious danger. It will make landfall north of Sri Lanka Sunday afternoon, creating widespread heavy rain along with strong winds that may cause significant damage. The higher terrain of this region will cause the cyclone to weaken in terms of its damaging winds.Cyclone “Jal” which is currently 600 Km away from Jaffna is expected to make landfall in Chennai tomorrow reducing its effects on Sri Lanka.
