Pakistan(National Times)- KARACHI: Several areas across Sindh continued to reel under a severe heatwave on Tuesday, with the Pakistan Meteorological Department (PMD) warning that the hot and humid conditions are likely to persist for the next few days. According to the PMD, temperatures in Karachi and other parts of the province are expected to remain unusually high, while strong winds may blow intermittently today and tomorrow, adding to the discomfort. The department also stated that a fresh westerly weather system is forecast to enter the upper parts of the country on May 1. This system is expected to influence weather patterns until May 5, potentially bringing a spell of rain to some areas. According to the PMD, under the influence of the westerly system, there is a possibility of rainfall in the upper regions of the country. Some parts of Sindh could also experience light to moderate rain between May 2 and 3. Earlier, the PMD had already issued a heatwave alert, warning that a high-pressure system developing over most parts of the country would cause temperatures to rise significantly above normal levels. Daytime temperatures in Sindh, southern Punjab and Balochistan are expected to remain 5–7 degrees Celsius above normal until at least May 1, while in central and upper Punjab, Islamabad, Khyber Pakhtunkhwa, Azad Jammu and Kashmir (AJK), and Gilgit-Baltistan, temperatures will stay 4–6°C above normal. A welcome relief is expected with the arrival of a new weather system around April 30, which could bring rain, wind, and thunderstorms to parts of AJK, Islamabad, the Potohar region, northeast Punjab, upper KP, and Gilgit-Baltistan. The PMD has urged citizens to avoid direct sun exposure during peak afternoon hours and to remain hydrated, particularly vulnerable groups such as children, women, and the elderly. Growers have also been advised to plan their wheat harvesting and protect their livestock, considering the prevailing and upcoming weather conditions.
