Canada: Heatwave impacting portions of southeastern and southwestern regions through at least Aug. 15
Heatwave impacting portions of southeastern and southwestern Canada through at least Aug. 15. Health concerns possible.
Event
Forecast models indicate that a heatwave will persist across portions of southeastern and southwestern Canada through at least Aug. 15. Temperatures of up to 32 C (90 F) are possible throughout much of the affected area. As of early Aug. 12, officials with the Meteorological Service of Canada have issued heat warnings for western British Columbia, New Brunswick, northeastern Newfoundland and Labrador, Nova Scotia, southern Ontario, and southern Quebec provinces. Authorities will likely issue new alerts or update existing advisories as weather conditions change over the coming day.
Hazardous Conditions
The 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. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration. The heatwave may make it more difficult for individuals to cool off in areas under restrictions due to coronavirus disease (COVID-19) activity.
Advice
Monitor local media for weather updates and related advisories. During heatwaves, 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 water that is bottled or 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.
