First summer stretch could see Tri-City temperatures rise to 30 C

Environment Canada has issued an alert as a hotter-than-normal system heads inland to places like Coquitlam, Port Coquitlam and Port Moody.
Tri-City recreation sites, like White Pine Beach in Belcarra, could likely be busy this weekend as temperatures will hover around 30 C, Environment Canada says.

It may not exactly be a heat wave, but stay cool and be prepared if you're planning to head outside this weekend.

Lower Mainland inland communities, like those across the Tri-Cities, could see the mercury rise to a higher-than-normal plateau during what experts are expecting to be summer's first stint of hot weather.

Environment Canada has issued an alert for Coquitlam, Port Coquitlam, Port Moody, Anmore and Belcarra as daily high temperatures are predicted to reach 30 C between Friday (June 24) and Tuesday (June 28).

Overnight lows will hover around the mid-teens, the national service says.

"With elevated temperatures, the risk of heat related illnesses increase," Environment Canada's special weather statement reads, which was officially put in place before 5 a.m. today (June 22).

As of this publication, the warm stretch is expected to peak Sunday afternoon (June 26) between 30 and 35 C.

"Temperatures are expected to return to near-normal values by the middle of next week as a cooler, unsettled air mass pushes onshore," the alert adds.

And great heat may result in great snow melt.

Environment Canada warns snow packs at higher elevations are likely to become more unstable, which leads to an increase in local water levels.

The BC River Forecast Centre still has a high stream flow advisory in effect for the lower Fraser River, which flows through Coquitlam and Port Coquitlam by way of channels and tributaries.
