Floods and landslides triggered by days of torrential rains have killed at least 99 people in Nepal since Monday.

In neighboring India, heavy downpours this week have also wreaked havoc, killing at least 88 people, while flooding roads, destroying bridges and causing landslides that washed away several homes.

Police in Nepal said rescuers were looking for at least 40 people who have been reported as missing, sparking fears that the death toll could rise.

A majority of the deaths occurred in the country’s eastern and western regions, which saw heavy rains this week, said police spokesperson Basanta Bahadur Kunwar.

“The search and rescue team have been relocating people to safer locations and taking the injured to the hospitals,” he said.

At least 35 injured in the rains have been rescued and are in the hospital.

Full damage being assessed

On Thursday, Prime Minister Sher Bahadur Deuba visited the flood-affected areas in the western region and directed authorities to focus on the speedy rescue, relief and rehabilitation of those vulnerable.

Authorities are still trying to ascertain the number of displaced households and the full extent of damages caused by the disasters.

Forecasters in Nepal are anticipating moderate rainfall later on Thursday but expect the weather to improve by the end of the week.

India has seen worrisome rains across several regions this week. Flooding and landslides caused by downpours over the week have killed at least 46 people in the northern state of Uttarakhand and 42 people in the southern state of Kerala, which is on alert for more rains in the coming days.

Landslides and floods are common in India’s Himalayan north. Scientists say they are becoming more frequent as global warming contributes to the melting of glaciers there.

In February, flash floods killed nearly 200 people and washed away houses in Uttarakhand.

In 2013, thousands of people were killed in floods there.
