Little relief for Lower Mainland overnight as heatwave persists

There’ll be little relief overnight as the Lower Mainland sees sweltering daytime temperatures.

CityNews Meteorologist Michael Kuss explains that although the next few nights will see the mercury get down to 16 to 18 degrees, it’s only for a very short amount of time.

“Briefly, it’s for a couple of hours,” Kuss said Monday. “There’s the humidity as well, and that will be the case again today.”

Kuss says Monday’s high of 33 could feel more like 37 in parts of the Lower Mainland.

“We’ll still have temperatures well into the mid-20s after sunset, which doesn’t come until 18 minutes after nine tonight.”

However, there will be a change of weather in the coming days, Kuss explains.

“There’s a bit of a break as we get toward the middle of the week. Wednesday will be a little bit cooler than today or tomorrow but still upper 20s,” he said.

“The coolest day will be Thursday, not only the daytime highs but also the overnight lows — that’s a lot closer to seasonal with highs of 22 to 27 degrees and a mild or a moderate morning low near 15. Friday it starts to creep back up again and we’re back into warmer air heading into at least the early part of the weekend.”

Environment and Climate Change Canada renewed its Heat Warning for Metro Vancouver and the Fraser Valley Monday morning. It’s comes after the weather service initially issued the warning on Saturday.

“A strong ridge of high pressure over the region has ushered in very high temperatures. Daytime highs will be in the low to mid 30’s inland and in the upper twenties along the coast,” the ECCC said in its warning.

“Watch for the effects of heat illness: heavy sweating, rash, cramps, fainting, high body temperature, and the worsening of some health conditions. Never leave susceptible people, particularly children, or pets inside a parked vehicle.

“If you are in an overheated area, seek a cool place such as a tree-shaded area, splash pad, misting station, or air-conditioned spot like a public building,” the ECCC said.
