New Delhi: The India Meteorological Department (IMD) on Monday (May 16, 2022) informed that the southwest monsoon has advanced into the Andaman and Nicobar islands and signaled the start of the four-month seasonal rains. In a weather bulletin, the IMD said that the Andaman and Nicobar islands and adjoining areas have been experiencing rainfall due to strengthening south-westerly winds in the lower tropospheric levels. 

"In view of strengthening of south-westerlies in the lower tropospheric levels, fairly widespread to widespread rainfall activity and persistent cloudiness over the area; Southwest Monsoon has advanced into some parts of South Bay of Bengal, most part of Andaman Nicobar Islands and the Andaman Sea today," the weather office said in a statement.

"Conditions are favourable for further advance of southwest monsoon into some more parts of south Bay of Bengal, entire Andaman Sea & Andaman Islands and some parts of east-central Bay of Bengal during next 2-3 days," the IMD added.

Earlier last week, it had said that the southwest monsoon was expected to reach Kerala by May 27, five days before the normal onset date of June 1, under the favourable weather conditions triggered by remnants of Cyclone Asani.

IMD's rainfall and thunderstorm forecast

Due to strong southwesterly winds from the Bay of Bengal to the northeast and adjoining East India at lower tropospheric levels, the IMD said that widespread light/moderate rainfall with isolated heavy to very heavy falls are very likely over Arunachal Pradesh, Assam, Meghalaya, and Sub-Himalayan West Bengal and Sikkim during next 4-5 days. Isolated heavy falls are very likely over Mizoram and Tripura during May 16-18, the IMD said.

"Isolated to scattered rainfall with isolated thunderstorm/lightning/gusty winds likely over Bihar, Jharkhand, Gangetic West Bengal, and Odisha during next 3-4 days," the weather office said.

The presence of cyclonic circulations over Lakshadweep and north Tamil Nadu coast is expected to bring fairly widespread rainfall with isolated thunderstorm/ lightning/gusty winds with isolated heavy to very heavy falls over Kerala, Coastal & South Interior Karnataka during the next five days, it added.

Isolated heavy rainfall is also expected over Tamil Nadu from May 16 to May 18 and over the Lakshadweep area from May 16 to May 17.
