Heat Warning

Issued at 16:15 Sunday 26 June 2022

Heat Warning for the first hot stretch of summer for the south coast.

Timespan: Today and Monday.

Locations: Lower Mainland.

Hazards: The Fraser Valley will see daytime highs rising to near 34 with an overnight low in the high-teens. Remaining regions such as Metro Vancouver and Howe Sound should continue to expect daytime highs rising into the low 30's with overnight lows down to the mid-teens.

The south coast is experiencing a stretch of much warmer than average temperatures through Monday. Temperatures are forecast to be in the mid to high 20's near the water and into the low 30's inland. However the Fraser Valley is expected to reach heat warning criteria where daytime highs could reach close to 34 today and tomorrow with an overnight low in the high-teens. There will be some respite from the elevated daytime temperatures as overnight lows fall into the mid-teens for the remaining regions.

With elevated temperatures, the risk of heat related illness increases.

Freezing levels rise throughout this event and will lead to an increase in snowmelt and snowpack instability. Increased stream flows due to run-off are probable.

Although heat is expected, bodies of water still remain cool for this time of year and may pose a risk of hypothermia with prolonged exposure.

Temperatures are expected to return to near-normal values by the middle of next week as a cooler, unsettled airmass pushes onshore.
