More than 100 people have died since Wednesday after unseasonably heavy rain lashed parts of India and Nepal, officials said, as the weather department predicted more rain for the region.

The Indian Meteorological Department (IMD) warned of multiple weather hazards on Wednesday, with heat wave conditions in the west and thunderstorms in the eastern and central regions, although the torrential rain associated with the monsoon usually starts in June.

At least 82 people have died in rain-related incidents in Bihar over the last two days, the eastern state’s disaster management department said.

In India’s most populous state of Uttar Pradesh, meanwhile, authorities said 18 people had died due to lightning and storm-related incidents.

In neighboring Nepal, lightning strikes and heavy rain killed at least eight people, National Disaster Authority officials said.

India’s weather office expects more rain with thunderstorms, lightning, and gusty winds over central and eastern India until Monday.

Intense heat waves in the summer months of the recent past have killed several people.

The state-run IMD said last week that India was expected to experience a much hotter April, with above-normal temperatures across most of the country.
