The Pakistan Meteorological Department (PMD) said on Saturday that the temperature in Karachi is likely to go up over the next few days.
The Met Office says that in the city over the next three days, the heat will get worse and the weather will stay muggy.
The temperature will stay between 36°C and 38°C. But the PMD says that winds could come from the west and southwest at this time.
The Met Department also said that there is a chance that the heat in central and upper Sindh will get worse on May 8 or 9. In the meantime, most of the state will have hot, dry weather.
But it might sprinkle in Dadu, Qambar Shahdadkot, Jacobabad, Jamshoro, and Tharparkar this evening or night.
In the next 12 hours, rain, thunderstorms, and a few hailstorms are likely in Upper Khyber Pakhtunkhwa, the Potohar region, Northeast Punjab, Islamabad, Kashmir, and Gilgit-Baltistan.
But there could be some heavy rain in northeast Punjab, Kashmir, and nearby hilly places during this time.
