The National Disaster Management Authority (NDMA) has issued a fresh heavy rain alert for Sindh, warning of very heavy downpours in Karachi, Hyderabad, Thatta, Badin, Mirpurkhas and Sukkur over the next 12 to 24 hours.

NDMA warns of urban flooding and flash floods

According to the NDMA, more than 50 to 100 millimetres of rainfall is expected in a short span, raising fears of severe urban flooding in Karachi, Hyderabad, Sukkur and Mirpurkhas. The authority also cautioned of possible flash floods in Thatta, Badin, Jamshoro and Dadu. Rising water levels in the Indus River and drains may cause flooding in low-lying areas.

Karachi Mayor Murtaza Wahab said in a press conference on Wednesday that Tuesday's rain had stopped around 8pm, during which Mangopir recorded 235mm of rain, Gulshan-e-Hadeed 202mm, and Karachi Airport 190mm. He said that Karachi received an average of 170mm to 175mm of rain in 12 hours.

He further said that Karachi's drains, which have a capacity of 40mm of rain, received an eight-fold increase of 240mm water.

The mayor admitted that the city faced difficulties but insisted that drainage operations were carried out promptly. He noted that major bottlenecks like the Nursery drain had been cleared, though heavy traffic delayed machinery access to Shahrah-e-Faisal.

“Rainfall was extraordinary, but our teams worked round the clock. I appeal to citizens to stay indoors and avoid unnecessary travel during urban flooding,” Wahab said.
