The upper air cyclonic circulation that has been triggering sustained rainfall over southeast peninsular coast has managed to claw its way up to southwest Madhya Pradesh.
Corresponding activity over the west coast and adjoining west and peninsular India has brought in moderate to heavy rainfall over parts of interior peninsula also.
WIDESPREAD RAIN
An India Meteorological Department (IMD) update said that widespread rainfall broke out over Konkan, Goa, coastal Karnataka, Lakshadweep and Andaman and Nicobar Islands during the 24 hours ending Sunday morning.
It was fairly widespread over Himachal Pradesh, east Rajasthan, east Gujarat, west Madhya Pradesh, Madhya Maharashtra, Marathawada, Telengana, Rayalaseema and Kerala.
Scattered rain fell during this period over Uttarakhand, west Rajasthan, the Northeastern States, Saurashtra, Kutch, east Madhya Pradesh, Chhattisgarh, Gangetic West Bengal, Orissa, Vidarbha, coastal Andhra Pradesh and Tamil Nadu.
WEATHER WARNING
A weather warning valid for Monday said that isolated heavy rainfall would occur over Gujarat and north interior Karnataka.
Isolated heavy rainfall has also been forecast over Konkan, Goa, coastal Karnataka and Kerala on both Monday and Tuesday.
A forecast by the Climate Prediction Centre of the US National Weather Services said that cross-equatorial monsoon flows into Arabian Sea would hold moderately strong until Friday.
Forecast for the next five days said that the flows could get even stronger leading to formation of ‘twin lows’ over the northwest Pacific.
STRONGER FLOWS
This would be followed a couple of days by the initiation of a potent upper air cyclonic circulation upstream over coastal Bay of Bengal.
Models differed in their interpretation of the area of formation, with the seas off Andhra Pradesh and Orissa variously being suggested as likely sites.
The net result is that there is another round of precipitation likely to be had for the west coast, west India and adjoining central India and holding forth until the end of the month.
This is expected to help prevent the rain deficit, having been contained at one per cent for over a week now, from deteriorating further.
