Heat warning issued for Vancouver as temperatures reach the 30s

Environment Canada issued a heat warning for Metro Vancouver and the Fraser Valley on July 22, warning that high temperatures could pose a risk to public health.

A ridge of high pressure is expected to bring daytime highs in the low to mid-30s, with overnight lows in the mid to high teens. Areas near the water in western Metro Vancouver are expected to remain in the high 20s. A gradual cooling trend is forecast to begin Thursday.

The agency says seniors, people living alone, people with pre-existing physical or mental health conditions, people with substance-use disorders and people with limited mobility face greater risk. It advises residents to check on higher-risk friends, family members and neighbours and to watch for symptoms such as heavy sweating, rash, cramps, fainting and high body temperature.

The City of Vancouver says indoor temperatures above 26 C can be dangerous for some people and temperatures of 31 C or higher can be dangerous for most. Cooling centres at community centres and libraries are open to everyone.

The city also points residents to more than 300 permanent and temporary drinking fountains, 30 misting stations, beaches, pools and spray parks as places to cool down.
