Churu in Rajasthan on Tuesday recorded 50 degrees Celsius, second highest in the last 10 years, followed by Palam in Delhi with 47.6 degree Celsius. The northwest and central parts of the country are reeling under severe heat wave conditions since May 23 this year while the India Meteorological Department (IMD) on Tuesday issued red warning for Assam, Tripura and Meghalaya from May 26 to 28 predicting very heavy rainfall in these two northeastern States.
According to the IMD, Churu had recorded 50.2 degree Celsius in 2016. Heat wave conditions will persist over Haryana, Chandigarh, Delhi, Rajasthan, Uttar Pradesh, east Madhya Pradesh, and Vidarbha till May 28. Hot weather conditions will also prevail in isolated pockets over Punjab, Chhattisgarh, interior Odisha, Gujarat, Maharashtra, interior Andhra Pradesh, Telangana, Bihar, and Jharkhand for the next two to three days.
“Due to prevailing dry northwesterly winds over plains, northwest, central and adjoining parts of the eastern India are reeling under the severe heat wave conditions,” the IMD said. Akola in Maharashtra recorded maximum temperature of 47.4 degree Celsius.
IMD director general Mrurunjay Mohapatra said that red-colour coded warning has been issued to Assam and Meghalaya for the next three days.
Sathi Devi, head of the IMD's national weather forecasting centre, said there is a strong flow of south-westerly winds from the Bay of Bengal, bringing a lot of moisture to these two States. This is aided by the orographic factors of these two states that will bring in very heavy rainfall, she added. Parts of Assam and neighbouring Meghalaya have been receiving extremely heavy rains since May 20 after super cyclone Amphan weakened. Cherrapunji has received 1,105 millimetres of rain in the last four days.
The IMD said rainfall is likely at most places, with heavy to very heavy rainfall is expected at isolated places. A few isolated will also receive extremely heavy falls, it added. Meanwhile, advancement of the monsoon which was hindered by super cyclonic storm Amphan will start from Wednesday, Devi said.
She added that the monsoon will start moving ahead in other parts of the Andaman and Nicobar archipelago and Bay of Bengal from Wednesday.
The water level of the Brahmaputra river is rising gradually due to continuous rainfall in the state. As per State Disaster Management Authority, five districts have been affected till now- Lakhimpur, Dhemaji, Dibrugarh, Darrang and Goalpara.
According to the IMD, the monsoon is likely to hit Kerala on June 5, four days after its normal onset date.
A low pressure area is also building up in the Arabian Sea from May 30, Mohapatra said. A low pressure area is the first stage of any cyclone. However, it is not necessary that every low pressure area intensifies into a cyclone.
The IMD has also cautioned fishermen along the coasts of Kerala, Karnataka not to venture out for deep sea fishing from May 30-June 4.
