A day after SNOW triggered a calamitous avalanche.
A day after it triggered a calamitous avalanche over the western Himalayas, the prevailing active western disturbance continued to bring in widespread rain or snowfall over Jammu and Kashmir and Himachal Pradesh.
Another fresh western disturbance has been forecast to affect the western Himalayas from Thursday with adjoining plains expected to be hit mainly around Saturday.
Scattered rainfall has been reported also from the plains over Punjab, Haryana, Rajasthan and Uttar Pradesh during the 24 hours ending Tuesday morning, an update by the India Meteorological Department (IMD) said.
HEAVY FALLS
Among stations recording heavy rainfall (in cm) were Batote and Banihal-13 each; Dharamshala, Bhaderwah and Quazigund-8 each; Bhuntar-7; Katra-6; Pahalgam, Kukernag and Shimla-5 each; and Sundernagar, Srinagar and Kupwara-4 each.
Satellite imagery showed convective clouds over parts of Jammu and Kashmir, Himachal Pradesh and Uttarkhand. Low and medium clouds (partly cloudy) were witnessed over parts of Haryana, Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand and Arunachal Pradesh.
An outlook by the US National Centres for Environmental Prediction (NCEP) said that the eastward-bound weather system would bring showers to east, east-central and North-East India during the week ending February 16.
East Uttar Pradesh, Bihar, east Madhya Pradesh, Chhattisgarh, Jharkhand, parts of Orissa and Vidarbha, north coastal Andhra Pradesh, Gangetic West Bengal, sub-Himalayan West Bengal and the entire North-East would be variously affected by the weather system.
Going forward, both the NCEP and the European Centre for Medium-Term Weather Forecasts (ECMWF) are suggesting the arrival of a fresh but weaker western disturbance around February 16 and 17.
SHOWERS FOR SOUTH
Meanwhile in the South, accentuation of a passing Madden-Julian Oscillation (MJO) wave is shown by models as touching off some activity over Sri Lanka and extreme southern peninsular India (south Tamil Nadu and Kerala) around this weekend (February 14 and 15). The MJO is a periodical upper level wave travelling east over the Indian Ocean that can amplify weather over ground.
The most active front of the western disturbance has moved east and a warning valid for the next 24 hours said that heavy to very heavy rain or snow would occur at isolated places over Jammu and Kashmir, Himachal Pradesh and Uttarkhand. Isolated hail storm may occur over Jammu division of Jammu and Kashmir, Himachal Pradesh, Uttarkhand and Uttar Pradesh.
Widespread rain or snow will occur over Jammu and Kashmir, Himachal Pradesh and Uttarkhand during next 24 hours and lessen in intensity thereafter.
Isolated to scattered rain or thundershowers would occur over plains of northwest India during the next 24 hours and decrease thereafter. Minimum (night) temperatures would fall by 3 to 4 degree Celsius as the skies clear up and the warmth brought to bear by the western disturbance taper off.
COLD AIR
Colder northwesterlies filling the plains would cause maximum temperatures (day) also to fall by 3 to 6 degree Celsius over the plains of northwest and adjoining east India over the next two days.
Minimum temperatures were above normal by 4 to 6 degree Celsius over most parts of northwest, west and central India, Bihar and West Bengal. But they were below normal by 2 to 5 degree Celsius over parts of Punjab from where the heavy clouding has apparently cleared out.
Forecast until Sunday said that scattered light to moderate rain or snow would occur over Jammu and Kashmir, Himachal Pradesh and Uttarkhand. Isolated rain or thundershowers have been forecast for Assam and Arunachal Pradesh.
