The northern limit of monsoon passes through Veraval, Navsari, Malegaon, Betul, Seoni, Ambikapur, Gaya, Patna and Raxol. The northern limit of monsoon is an imaginary line that connects places where the monsoon has reached at a given point in time.
A cyclonic circulation developing in head Bay of Bengal would help to enhance rainfall activities over Gangetic West Bengal, Jharkhand, Bihar, and also over north Orissa and Chhattisgarh by early next week. A further advancement of monsoon is thus expected over most part of Chhattisgarh, Orissa, Jharkhand and Bihar over the next week.
The southwesterly surge along north coastal Maharashtra has weakened and the area would receive only light rain but southern parts of the west coast would continue to receive moderate to heavy showers. The off shore trough is still stronger in these parts.
Scattered light rain would continue over southern peninsular India and Madhya Pradesh.
Light to moderate rainfall would continue over northeast India albeit in lesser intensity and spread due to squeeze in the moisture incursion from the Bay.
Easterly winds have reached the foothills of east Uttar Pradesh and humidity has increased over the area. These weather conditions are underscoring the precursor to the onset of southwest monsoon over these parts.
