India Meteorological Department (IMD) has called it curtains for year 2011 north-east monsoon rains for peninsular India.
Very severe cyclone ‘Thane' would appear to have set up the swansong for the season, not without leaving a trail of destruction over Puducherry and adjoining Tamil Nadu coasts.
‘NORMAL' SEASON
Southern peninsula ended up in the ‘normal' side of the seasonal precipitation sweepstakes (as per IMD classification) as on December 31, 2011. The Met sub-division of Tamil Nadu and Puducherry accounted for the most of the rainfall, recording 22 per cent more than the seasonal normal.
All three sub-divisions of Andhra Pradesh and adjoining north interior Karnataka witnessed poor rains this season. Telangana (-85 per cent) was the worst-hit. International weather models suggested that coastal Andhra Pradesh and adjoining regions of Tamil Nadu would receive light showers during the week ahead. The IMD has already located an upper air trough in the easterlies looking east-northeast from north Karnataka to northwest Jharkhand across Telangana and Orissa.
COLD WAVE
Meanwhile, north and north-west India continued to shiver under cold wave conditions with mercury plunging to 2 deg Celsius in Amritsar in the plains.
A fresh western disturbance is expected to affect western Himalayan region and adjoining plains during the course of the week bringing back snow, fog and rains over disparate regions of the north and northwest. An IMD weather warning valid for the next two days said that dense fog would reduce visibility would to 200 metres or less during morning hours over some parts of east Uttar Pradesh and Bihar.
The passage of the western disturbance and its warmth to the east of the country has left the northwest literally in bitter cold.
FURTHER FALL
Cold wave along with ground frost conditions has been forecast over parts of Punjab, Haryana, north Rajasthan, north Madhya Pradesh and west Uttar Pradesh.
An outlook until Friday said that minimum temperatures would fall by 2 to 3 deg Celsius over parts of northwest, adjoining central and east India. An IMD update for the 24 hours ending Tuesday morning said that Punjab, Haryana, west Uttar Pradesh, Rajasthan, Gujarat, west Madhya Pradesh and north Maharashtra went through near-frigid conditions.
Rain or snowfall occurred at a few places over Uttarakhand and at one or two places over Himachal Pradesh.
Towards the east, rains came down at many places over Jharkhand, Gangetic West Bengal and Orissa and at a few places over Bihar, the North-eastern States and Chhattisgarh.
