Queensborough Middle School, BC

First hot stretch of the summer for the south coast.

Timespan: Now through Monday.

Locations: Lower Mainland and Sea to Sky.

Hazards: Daytime highs rising into the low 30's with overnight lows down to the mid-teens.

The south coast will experience a stretch of warmer than average temperatures. Inland temperatures will reach into the upper 20's. Through the weekend and into early next week, temperatures in the low 30's are forecast. There will be some respite from the elevated daytime temperatures as overnight lows fall into the mid-teens.

With elevated temperatures, the risk of heat related illnesses increase.

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.
