The India Meteorological Department (IMD) on Wednesday predicted very heavy rainfall over West Bengal, Sikkim, Assam, Meghalaya, Uttar Pradesh and Bihar over the next few days. According to the IMD, a low-pressure area lies over central parts of west Madhya Pradesh and neighbourhood with associated cyclonic circulation extending up to mid-tropospheric levels. It is likely to become less marked by September 24. However, it’s associated cyclonic circulation likely to recurve northeastwards during the next 3-4 days. India received 918.3 mm rainfall as against the normal of 849.2 mm, an increase of 8 percent so far. Uttar Pradesh, Himachal Pradesh, Jammu and Kashmir, Nagaland, Manipur and Mizoram are among those states which received less rainfall this monsoon.
“High convergence over the northeast and adjoining east India very likely due to strong moist southerly/southwesterly winds from Bay of Bengal at lower tropospheric levels till September 26. A trough runs from northeast Uttar Pradesh to north Maharashtra at lower & middle tropospheric levels. It is very likely to persist until September 24,” IMD said.
Under the influence of the above systems, fairly widespread to widespread rainfall with isolated heavy to very heavy falls are very likely over Assam and Meghalaya on September 24; Sub-Himalayan West Bengal & Sikkim; East Uttar Pradesh till September 25 and Bihar on September 26.
Thunderstorm with lightning at isolated places very likely over Uttarakhand, Uttar Pradesh, Vidarbha, Chhattisgarh, Bihar, Gangetic West Bengal, Gujarat state, Madhya Maharashtra, Marathwada, Coastal Andhra Pradesh & Yanam, Telangana and Tamilnadu, Puducherry & Karaikal. Strong Wind (speed reaching 45-55 kmph) very likely over Southwest Arabian Sea. Fishermen are advised not to venture into these areas.
