According to the Meteorological Department, temperatures in some southern areas may reach 44 to 45°C by the end of the week.

Karachi is likely to see increased heat intensity in the next 24 hours, with maximum temperatures between 36 and 38°C.

Humidity levels around 66% are expected to make conditions feel more severe.

Sindh districts, including Hyderabad, Jacobabad, Dadu and Jamshoro, may experience temperatures exceeding 44°C.

A heatwave-like situation is also expected in central and southern Punjab, while northern and upper parts of the country may receive temporary relief through dusty winds and occasional rain.

Meteorologists say the rise in temperatures in early May is linked to climatic changes, with no major chances of rain in the near future.

Sindh Chief Minister Murad Ali Shah has placed the administration on high alert and directed the immediate establishment of heatwave relief camps in affected areas.

He also ordered special arrangements for patients in hospitals.

He advised people in Jamshoro, Dadu, Ghotki and Sanghar to take precautionary measures, including avoiding unnecessary exposure to heat.

He urged citizens to cover their heads, drink more water, stay in shaded areas and avoid working under direct sunlight.

Workers were told to continue their duties but prioritise their health.

Medical experts have advised avoiding direct sunlight, especially between 11am and 4pm, while urging extra care for the elderly, children and outdoor workers to prevent heatstroke.

Karachi is currently experiencing western winds at a speed of 11 kmph, providing slight relief during mornings and evenings, but daytime heat is expected to remain intense.
