Unseasonal weather activity is coming up over the central and eastern parts of the country. The spell makes a mild start tomorrow and grows in intensity and spread. Embedded circulation developing near the coastline will drag the inclement weather deep inside the eastern states. Damaging rains, hailstorms and strong winds pose a serious threat to the standing crops, over the area. Brunt will be faced by West Bengal, Odisha, Jharkhand and Coastal Andhra Pradesh. Peripherals of Telangana, Vidarbha and East Madhya Pradesh will be the extended arm of the weather activity.
Pre-monsoon heat has been building up largely over the interiors of Peninsular India. It has spared the vulnerable pockets of interior Odisha, South Chhattisgarh and parts of Gangetic West Bengal. Even, heat prone areas of north Telangana have missed the action, so far. With an unseasonal spell of weather activity coming up, the usual heat wave may skip the region, in the coming week.
It all starts with the converging winds from the Bay anticyclone and dry circulation over Maharashtra and Madhya Pradesh. The zone of confluence starts with mild activity over Vidarbha, South Chhattisgarh and the interiors of Odisha, tomorrow. It grows in space and time over the next two days and stretches across, Vidarbha, East Madhya Pradesh, South Chhattisgarh, Odisha, Jharkhand and West Bengal. Finally, an in-situ cyclonic circulation is likely to appear over the tri-junction of Odisha, Chhattisgarh and Jharkhand, with peripheral reach in the adjacent areas, on 19th Mar. A fairly strong system moves eastward and reaches parts of Gangetic West Bengal, Odisha and North Coastal Andhra Pradesh, on 20th March. The weather activity will peak on two days, 19th & 20th March. It is likely to ease out, the next day, as the circulation moves to the north Bay of Bengal. Broad clearance can be expected from 22nd March onward.
The Spread and intensity of the weather will be maximum on the 19th and 20th March. The involved areas can expect typical pre-monsoon activity. Strong thunderstorms, powerful lightening strikes, swaying gusty winds and heavy rains will impact large parts of these states. Hailstorms, in some places, will compound the situation further. Farmers will bear the risk of potential damage to the standing crops. Waterlogging in the fields and lodging of tall crops is quite likely. Exercise caution to avoid lightning strikes, while working in the open fields and observe precautionary measures to minimize the losses.
