Stay alert to rapidly changing conditions and provide a safe place to quickly take shelter if your location falls under an alert. More on what to expect Tuesday and into the long weekend, below.

THIS WEEK: COOL TEMPERATURES AS STORM RISK RISES
British Columbia’s first heat event of 2022 announced it would begin in the last week of June. Although the readings were a long way from the historic heat we saw a year ago, temperatures climbed into the low to mid-30s in many places in the region.
Cooler air pushing inland on Tuesday will wipe out the first heat event of the season on the south coast.
Tuesday’s maximum temperatures will be up to 10 degrees cooler than Monday’s warm temperatures along the coast, while temperatures inland will drop about five degrees.
Despite the cooler temperatures, cold air in the air will create enough instability to trigger a series of thunderstorms for some people inland.
Environment and Climate Change Canada (ECCC) issued early thunderstorm forecasts Tuesday morning for the Okanagan Valley, North Thompson, Cariboo, Shuswap, Arrow Lakes, Slocan Lake and 100 Mile.
The strongest thunderstorms that form over inland can cause heavy rainfall, strong wind gusts and large hail.
Lightning poses a significant risk to your safety, even if a thunderstorm does not reach serious limits. ECCC added in its severe thunderstorm: “Lightning kills and injures Canadians every year. Remember, if the thunder roars, get inside!”
