The monsoon has not progressed from Sunday’s alignment but rain or thundershowers lashed South Gujarat and the Konkan-Goa belt on the West Coast on Monday.
This was the handiwork of the remnant of erstwhile cyclone ‘Nanauk’ that hovered over Northeast Arabian Sea but washed over on Monday along the coasts of Gujarat.
Sparks thunderstorms The system is expected to be active over land for two more days, according to an India Meteorological Department update. Overnight on Monday, the system also sparked off thunderstorms over Himachal Pradesh, Uttarkhand, Punjab and Uttar Pradesh. This caused extreme heat to shift to the east over coastal Andhra Pradesh, Chhattisgarh and Gangetic West Bengal. In the North-West, only Rajasthan retained the high mercury levels of around 43 deg Celsius.
Dynamics in East Apart from most places over Konkan and Goa, rain was also reported at many places over south Gujarat, east Madhya Pradesh, Madhya Maharashtra and Vidarbha during this period. Meanwhile, eastern parts of Bay of Bengal have started receiving fresh rains indicating a revival of monsoon in the area. The causative cyclonic circulation hung in over northeast Bay of Bengal.
Models differed in their outlook on the cyclonic circulation or a low-pressure area evolving from it that would preside over the proceedings over East India.
Monsoon easterlies are forecast to meet up with the western disturbance setting up a narrow corridor of two-way flow of winds along the foothills of the Himalayas.
