Isolated very heavy falls also very likely over Bihar on October 19 and over sub-Himalayan West Bengal and Sikkim on October 20. Isolated extremely heavy falls are also likely over sub-Himalayan West Bengal and Sikkim on October 19, the IMD said.
Due to strong southerly/south-easterly winds from Bay of Bengal over northeast India during October 19 till 21, fairly widespread to widespread light to moderate rainfall with heavy rainfall very likely over northeast India till October 21, and isolated very heavy falls also very likely over Arunachal Pradesh and Assam and Meghalaya on October 19 and 20.
