Canada: Red heat warnings issued for multiple regions as of Aug. 11
Heat warnings in place for parts of Alberta, British Columbia, Manitoba, Northwest Territories, Nunavut, and Saskatchewan, Canada, Aug. 11.
Environment Canada is maintaining red heat warnings (the highest level on a three-tier scale) across parts of central and northern Alberta, northeast and southeast British Columbia, northern Manitoba, southern Northwest Territories, eastern Nunavut, and central and northern Saskatchewan, Aug. 11. The warnings were issued Aug. 10. Officials have indicated that high temperatures are forecast through the early part of the week of Aug. 12. Authorities could update and possibly extend the coverage of weather alerts over the coming days.
The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke. 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.
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 stress 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.
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 the case prolonged electricity outages occur.
