Pakistan’s cultural city of Lahore saw record-high rainfall early on Thursday leaving at least one person dead as streets and hospitals flooded, officials said.

The downpour started before dawn and is expected to continue for a week at intervals, according to the National Disaster Management Authority. In an advisory, it said the rains are likely to cause flash flooding and landslides.

The monsoon rains also lashed Pakistan’s capital, Islamabad, and other areas.

The latest spell of rains in Lahore was so heavy that it quickly flooded many streets and rainwater entered some wards in the Jinnah and Services hospitals in the capital of Punjab province, causing problems for patients undergoing treatment there.

At least one person died after being electrocuted in the Nishat Colony neighbourhood, police said.

Some areas in the city received a record-high 353mm (14 inches) of rainfall in a few hours, breaking a 44-year-old record in Lahore, according to the water and sanitation agency. In a statement, it said efforts were under way to pump rainwater off main roads.

Drainage systems quickly became overwhelmed after the rains, flooding several residential areas, officials said. The rainwater entered scores of homes in various parts of the city, residents said.

Monsoon rains have returned to Pakistan as the country is still struggling to recover from devastating 2022 floods that affected 33 million people and killed 1,739. But weather forecasters say the country will receive less heavy rains compared with 2022, when climate-induced downpours swelled rivers.

Pakistan recorded its wettest April since 1961, with more than double the usual rainfall for the month. Weather forecasters and scientists have blamed climate change for the unusually heavy monsoon rains.
