Moisture incursion sets up heavy weather over east

Moisture incursion from the Bay of Bengal and the North-eastern States due to strong southerly to south-westerly winds has been triggering heavy to very heavy overnight rains over these regions.

Assam Pounded

An India Meteorological Department (IMD) update on Tuesday said that fairly widespread rainfall has occurred over Assam and Meghalaya while it was scattered over Arunachal Pradesh, Manipur and Tripura.

Very heavy to extremely heavy rainfall has been reported from Cherapunji (36 cm), Rangia (13 cm) Agartala and Itanagar (11 cm each), Silchar (10 cm), Tezpur (9 cm) and Guwahati (8 cm) during the 24 hours ending Tuesday morning.

Satellite imagery on Tuesday morning revealed convective clouds (rain-generating clouds) over parts of Assam and Meghalaya.

The moisture incursion is set to continue over the north-east and West Bengal, and the possibility of thundershowers has enhanced, thanks to prevailing elevated convective available potential energy (Cape) values.

A warning valid for the next two days said that isolated heavy to very heavy rainfall with thunder squall would occur over Assam, Meghalaya and Arunachal Pradesh during the next two days.

Fresh Westerly

The weather-setting north-south trough ran down from Bihar to south Tamil Nadu across Jharkhand, Chhattisgarh and Andhra Pradesh in lower levels.

Over North-west India, a fresh western disturbance is approaching western Himalayan region, which would be active over the region for the next four days, the IMD said.

Thunderstorm activity is also prevalent towards the South with peninsular seas also warming up to the occasion.

Convective clouds were seen over Jammu and Kashmir and the south Andaman Sea, while low to medium clouds (partly clouded conditions) hung in over Himachal Pradesh, Uttarkhand, Orissa, south Peninsular India, remaining parts of the north-east, south Arabian Sea and south Bay of Bengal.

Forecast until Friday said that fairly widespread rain to thundershower activity would continue over Arunachal Pradesh, Assam and Meghalaya and scattered over Nagaland, Manipur, Mizoram and Tripura.

Scattered rain or thundershowers are likely over Jammu and Kashmir, Himachal Pradesh and isolated over Uttarkhand.

Isolated rain or thundershowers are likely over coastal and south interior Karnataka, Kerala, Tamil Nadu, Lakshadweep and the Andaman and Nicobar Islands.

Squall In Punjab

Isolated rain or thundershowers accompanied with squall are likely over Punjab and Haryana during the next two days. This could prove damaging for the standing wheat crop.

Isolated rain or thundershowers accompanied with squall would also occur over Orissa and north coastal Andhra Pradesh.

Meanwhile, severe heat wave conditions prevailed over isolated pockets of Punjab, Haryana and north Rajasthan overnight on Tuesday.

Heat wave conditions prevailed over the remaining parts of Punjab, Haryana and north Rajasthan, many parts of Jharkhand, Chhattisgarh, north Orissa, Vidarbha, Delhi, Chandigarh and isolated pockets of Telangana.

For a second day running, the maximum daily temperature was driven away to the east as a prevailing western disturbance loomed large and its calming influence prevailed over hilly regions of the north-west.

The day's maximum of 46.3 deg Celsius was recorded at Jamshedpur in Jharkhand.

A warning for the next 24 hours said that heat wave conditions would continue over parts of Rajasthan, Haryana, Delhi, Punjab, Jharkhand, interior Orissa, north Chhattisgarh and Vidarbha during the next 24 hours.

But maximum temperatures are expected to fall by 1 to 3 deg Celsius over parts of northwest and central India during the next three days with a follow-up western disturbance assuming centre-stage over the north-west.

This may lead to abatement of heat wave conditions from some parts of the region. But no significant change in maximum temperatures is indicated over East India.
Rainfall on 20-Apr, Very heavy over N-E states, Widespread over Himachal, Kashmir and over Kerala and N-W Tamilnadu..
Maximum temperatures would fall by 1-30C over many parts of northwest and central India during next 2-3 days.
Isolated heavy to very heavy rainfall with thunder squalls would occur over Assam and Meghalaya and Arunachal Pradesh during next 48 hours
On 20-Apr, Highest maximum Temperature of 46.4°C was recorded at Bankura (West Bengal).
Trough from Bihar to northwest Bay of Bengal across Jharkhand and north Orissa in lower levels persists
Severe heat wave conditions are prevailing over isolated pockets of Punjab, Haryana, north Rajasthan, Jharkhand and north Orissa.
