We begin with the good news first. As predicted by Skymet, the Southwest Monsoon has arrived over Andaman and Nicobar Islands on last Saturday, 4 days prior to its official date of May 20.
The Northern Limit of Monsoon (NLM) is currently passing through Long Island and the weather conditions for its further advancement are also favourable over some more parts of Bay of Bengal, through Sri Lanka.
With this, we are expecting Monsoon to strike Kerala, 3 to 4 days earlier than the official onset date of June 1.
Meanwhile, South India continues to witness fairly widespread rain, with intensity varying from moderate to heavy. However, rain intensity over parts of Tamil Nadu will now reduce.
A cyclonic circulation is prevailing over Bihar and adjoining area with trough extending up to Maharashtra. As a result we can expect isolated thunderstorm activities over Bihar, Jharkhand, Chhattisgarh, West Bengal, Telangana and Vidarbha region.
Squally winds with the speed of 60 to 80 kmph cannot be ruled out.
Another feeble cyclonic circulation over Northeast region will continue to give scattered rain over Northeastern states.
Moving onto North India, the region continues to reel under hot weather conditions. However, a fresh Western Disturbance is affecting Jammu and Kashmir, which is expected to trigger Dust storms and thunderstorms on Tuesday over the plains of Northwest India including parts of Delhi, Haryana and Punjab.
Meanwhile, Parts of Rajasthan, Gujarat, Maharashtra and west Madhya Pradesh continue to be the hottest pocket of the country, with extremes exceeding 45°C.
