The India Meteorological Department (IMD) on Friday forecast heavy rainfall in parts of Bihar, Maharashtra and Himachal Pradesh and warned of low to moderate “flash flood risk” in 13 districts of Bihar over the next 24 hours.

IMD issued warnings for heavy to very heavy rainfall across Mumbai and Maharashtra, with significant impacts expected over the coming days. Following the recent trend of erratic monsoons, Mumbai is bracing for widespread rain, particularly in the Konkan region, which is anticipated to experience intense downpours today.

According to the latest bulletin by the Met Department, a cyclonic circulation lies over north-central Maharashtra, and, under its effect, Maharashtra is expected to witness more downpour in coming days.

Heavy rain is likely in West Champaran, East Champaran, Sitamarhi, Sheohar, Muzaffarpur, Gopalganj, Siwan, Saran, Vaishali, Patna, Jehanabad, Madhubani and Bhojpur districts, it said in a bulletin. These districts are at the risk of “low to moderate flash floods in the next 24 hours”, the Met Department said. A large number of people from the affected districts have been evacuated and brought to relief camps.

The Shimla meteorological department issued a ‘yellow’ alert for heavy rains at isolated areas of Himachal Pradesh. A total of 47 roads including National Highway 707 were closed for vehicular traffic in Himachal Pradesh following rains, officials said on Friday.

The highest number of 25 roads were closed in Sirmaur, including NH 707 connecting Hatkoti in Shimla district and Paonta Sahib in Sirmaur district, ten in Kangra, eight in Mandi, two in Kullu and one each in Kinnaur and Shimla districts, according to the State emergency operation centre (SEOC).
