Pakistan ordered businesses, schools and public offices in Karachi to shut on Wednesday after torrential monsoon rain left at least 10 people dead in the densely populated port city, with more heavy downpours predicted.

The National Disaster Management Authority (NDMA) said on Wednesday that 11 people were killed in Gilgit-Baltistan in the north and 10 others died in Karachi, Pakistan’s financial hub, where heavy rain triggered electrocutions and house collapses.

The Flood Forecasting Division reported that Tarbela Dam has reached 99 percent of its capacity at 1,549.20 feet, while Mangla Dam is 76 percent full at 1,219.40 feet. Levels at Rawal, Khanpur, and Simly dams have also risen significantly, prompting authorities to open spillways at some reservoirs to ease pressure.
