Vancouver Weather: How Long Do Wind and Heat Warnings Last?

Vancouver Weather: How Long Do Wind and Heat Warnings Last?

The Metro Vancouver region is experiencing poor air quality and above-average heat.

The weather forecast for Metro Vancouver includes a heat warning and an air quality advisory.

While the extreme heat will soon subside, temperatures are expected to remain above average throughout the week.

Ken Dosanjh, a meteorologist with Environment Canada, said the heat warning remains in effect for the Lower Mainland. Inland, temperatures will be around 30 degrees Celsius, but with high humidity, it will feel more like 30 degrees Celsius.

According to VIA’s Trout Lake Weatherhood station in Vancouver, the high on Tuesday (July 9) is 30°C and the low at night is 19°C.

The high temperatures could persist throughout the night but could also drop below heat warning criteria before Wednesday, Dosangh told VIA

“Wednesday will be unsettled, with temperatures inland around 29 degrees Celsius,” he said, adding that daytime temperatures need to be around 29 degrees Celsius and fall around 16 degrees Celsius to meet the criteria for public health risks.

A ridge of high pressure has been holding warm air from the south, blocking other coastal systems and pushing air away. However, that ridge is expected to move toward Alberta on Wednesday.

Air Quality Advisory Issued for Metro Vancouver

Metro Vancouver also issued an air quality advisory for the region on Monday due to elevated ground-level ozone levels that are expected to persist for several more days. It will remain in effect until further notice.

According to Dosanjh, the local emissions, combined with the higher temperatures and amount of sunlight, have led to more smog.

Environment Canada may lift its heat warning for Metro Vancouver if minimum temperatures fall to around 15 degrees Celsius on Tuesday evening. However, the warning may remain in effect for longer.

“We expect the heat warning to be lifted by Thursday at the latest,” he said.

Temperatures are expected to remain a few degrees above seasonal averages through the weekend, with more above-average heat and drought expected next week.

The rest of July also shows an above-average signal, although the long-range forecast does not show individual weather events. Metro Vancouver typically experiences its warmest temperatures toward the end of July and into August.

Dosanjh advises locals to stay cool and hydrated during the heatwave. They should also seek shade or use air-conditioned public facilities during the hottest part of the day from 1pm to 4pm.
