IMD Says Monsoon To Hit Andamans Around 16 May Warns Of Severe Heatwaves In Northwest India

(MENAFN- Live Mint) NEW DELHI: Conditions are turning favourable for the crucial southwest monsoon to advance into parts of the south Bay of Bengal, Andaman Sea and the Andaman and Nicobar Islands around 16 May, even as large parts of northwest, west and central India brace for intense heatwave conditions in the coming week, according to the India Meteorological Department's (IMD) latest update.

A well-marked low-pressure area over the southwest and adjoining west-central Bay of Bengal is aiding the progress of the monsoon current, while multiple upper-air cyclonic circulations over north and central India and a western disturbance over Jammu and adjoining regions are shaping weather patterns across the country, the weather forecaster said on Wednesday.

The Indian mainland usually sees the onset on 1 June, marking the beginning of the southwest monsoon season (June to September).
