Pakistan: High temperatures forecast across much of the country through at least May 13
High temperatures forecast across much of Pakistan through at least May 13. Transport and power disruptions possible.
Event
High temperatures are forecast across much of Pakistan through at least May 13. The Pakistan Meteorological Department has warned of rising temperatures across most of the country in the coming days, with the most intense heatwave conditions likely in the southern half of the country. Daytime temperatures of 3-5 C above normal for the time of year are forecast in parts of Sindh, southern Punjab, and Balochistan provinces. Maximum temperatures of around 44 C (111 F) are possible in parts of central and northern Sindh Province over the coming days. Temperatures of 2-3 C above normal are forecast in northern and central Punjab and northern Khyber Pakhtunkhwa provinces, as well as Islamabad Capital Territory and Azad Jammu and Kashmir and Gilgit-Baltistan administrative territories. Authorities are advising the general public to avoid unnecessary exposure to direct sunlight and farmers are being advised to manage the watering of crops accordingly.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. High temperatures can also cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to the hospitalization of some passengers due to dehydration.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur as very high temperatures put more stress on vehicles, making tire blowouts more common. Major flight disruptions are unlikely, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
Advice
Monitor local media for weather updates and related advisories. During heat waves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating - drink bottled water or water that has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
