Pakistan: Heatwave conditions forecast across much of the country through at least June 24
Heatwave conditions forecast across much of Pakistan through at least June 24. Transport and power disruptions possible.
Event
Forecast models indicate that a heatwave will persist across much of Pakistan through at least June 24. The Pakistan Meteorological Department has warned that temperatures are likely to increase gradually across most of the country June 20-24. Daytime temperatures of 4-6 C (7.2-10.8 F) above normal are forecast over northern Khyber Pakhtunkhwa, northern and central Punjab provinces, Azad Kashmir and Gilgit-Baltistan autonomous territories, and Islamabad Capital Territory. Daytime temperatures of 2-4 C (3.6-7.2 F) above normal are likely over Balochistan, southern Punjab, and Sindh provinces. Occasional dust storms and thunderstorms are forecast in the plains and hilly areas of the country.
The high temperatures are likely to result in increased energy and water demand. Authorities are advising the general public to avoid unnecessary exposure to direct sunlight and take precautions to avoid heatstroke. Farmers are advised to manage the watering of crops.
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 speed. 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 engines, 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.
