The Assam government sounded a flood alert on Tuesday after heavy rains over the last two days triggered flash floods and breach in roads and embankments in many parts of the state.
A central water commission bulletin said the Brahmaputra river and its tributaries were flowing above the danger mark in at least eight places. Up to 800 villages across four districts — Lakhimpur, Dhemaji, Sonitpur and Jorhat — have been affected so far.
Nearly 150,000 people have been displaced. According to officials, they have been accommodated in makeshift camps.
"National Disaster Response Force teams have been deployed in sensitive places. We have started distributing relief material," said Anowar Uddin Choudhury, deputy commissioner, Lakhimpur.
Heavy rains also lashed several parts of Maharashtra, specially the Konkan region and western parts of the state. Several villages were cut off as rising river water levels submerged the roads.
Heavy rains and landslides, particularly between Ratnagiri and Nivsar, led to disruption of train services on the Konkan Railway route.
Many trains including Trivandrum Rajdhani, Goa Sampark Kranti and Ernakulum Duronto have been diverted.
The Konkan Railway has announced cancellation of services till July 21.
In Gujarat, the Saurashtra region has received heavy rainfall over the last three days. Irrigation department officials said three dams are overflowing, while two others are on high alert. Small and medium check dams also are also overflowing.
Six people died in rain-related accidents in the region.
Ganga, Yamuna and Sharda rivers in UP were overflowing as heavy rains continued to lash the state on Tuesday.
Ganga is rising in Allahabad, Mirzapur, Varanasi, Ghazipur and Ballia districts. The Yamuna is rising in Mohna, Agra, Hamirpur, Banda and Allahabad districts. Four schoolchildren drowned in an overflowing stream in Gonda district.
