Arrival of the South West Monsoon

The South West Monsoon has arrived over the Andaman and Nicobar islands. IMD will declare its onset within the next 24 hours. 

Two low pressures are forecast to come up on either side of the  peninsula within the next 72 - 96 hours and drag monsoon winds onto the mainland. However, the Arabian sea low is forecast to end up in Oman and could cause a delay of about 2 days in the onset over Kerala. The North-West of the country is heating up considerably and the annual Low pressure area will form over parts of Rajasthan and Madhya Pradesh, further strengthening Monsoon flows on the mainland. 

Expected date of Monsoon onset over Kerala is between 29th and 31st of May.
