New Delhi: The flood situation in Bihar remained grim on Monday, while central authorities warned some hill districts in the north of likely flash floods and landslides as heavy rains disrupted normal life in parts of the country.
At least seven people drowned in flooded water bodies in Rajasthan and Madhya Pradesh, and the Central Water Commission (CWC) said its 15 stations in Bihar, six in Assam, four in Uttar Pradesh, two in Telangana and one each in Andhra Pradesh, Jharkhand, Odisha and West Bengal recorded Severe Flood Situation'.
Meanwhile, an IMD forecast said enhanced rainfall activity with heavy to very heavy falls is very likely over northwest India including Western Himalayan region till August 20 and decrease thereafter.

The CWC issued a flood advisory for several states, warning some hill districts in the north of likely flash floods and landslides.
The advisory for Himachal Pradesh, Punjab, Haryana, Uttarakhand, Uttar Pradesh said there is a likelihood of a rise in water levels in several rivers including the Ganga, Sutlej, Ravi, Beas, Ghaggar and Yamuna due to the heavy to very rains forecast there.
There is a likelihood of flash floods in some of the hill districts in these states in association with cloudburst. Necessary precautions have to be taken for possible landslides and blockages of river flows due to landslides in high ranges of these states, it said.
The Indian Air Force (IAF) deployed its MI-17 helicopter to rescue a 43-year-old man who remained stranded on a tree for over 12 hours amid overflowing water discharged from a dam in Chhattisgarh's Bilaspur district.
In Bihar, the floods have affected 81.56 lakh people in 16 districts. So far, 25 people have died in flood-related incidents.
The water level in Ganga continued to rise on Monday, increasing by 5-24 cm in Buxar, Munger, Bhagalpur, Kahalgaon, and at Digha Ghat in Patna, as per a bulletin issued by the state Water Resources Department.
The river's water level at the Gandhi Ghat in Patna was 48.62 meters, which is 2 cm above the danger mark, it said.
Several other rivers, including Baghmati, Burhi Gandak, Punpun, Khiroi and Ghaghra, are flowing above the danger level at different places in the state.
In Uttar Pradesh, where 15 districts are hit by floods, Chief Minister Yogi Adityanath directed officials to maintain social distancing in relief camps. He asked them to segregate those who have fever, cold and headache and get them tested for COVID-19 if required.

The deluge has affected 788 villages in 15 districts, he said. Among the affected villages, 454 are marooned.
Meanwhile, Odisha, which witnessed a flood-like situation in several areas, is likely to get more downpour over the next few days with a fresh low-pressure area brewing over the Bay of Bengal.
While many parts of the state have been battered by heavy rainfall due to three back-to-back low-pressure areas so far this month, a new one is likely over the Bay of Bengal around August 19 and bring more downpour, the Meteorological Centre in Bhubaneswar said.
Heavy downpour since August 13 has created a flood-like situation in several parts of Odisha, snapping road connectivity, damaging mud houses and crops, and killing two people, officials said.
In the worst-hit Malkangiri district, low-level bridges connecting various block headquarters were inundated, temporarily disrupting the road connectivity, district collector Manish Agarwal said.
Normal life was affected at various places in Telangana too on Monday due to the incessant rains lashing the state for the past few days.
The flood level in Godavari river at Bhadrachalam was 60.7 ft, crossing the 3rd Warning Level, at 1300 hours on Monday, official sources said.
In the neighbouring Andhra Pradesh, the Godavari river is swelling by the hour, inundating more villages along the course, as it inched towards a record flood level.
As the water level crossed 60 feet at Bhadrachalam in neighbouring Telangana, the Sir Arthur Cotton Barrage at Dowaleswaram near Rajamahendravaram received 18.27 lakh cusecs by noon on Monday.
