Environment Canada has issued a heat warning for Metro Vancouver for the first hot stretch of the summer.
The warning issued Sunday is in place until Monday for Vancouver, Burnaby, New Westminster, the North Shore, Coquitlam Maple Ridge, Surrey, Langley, Richmond and Delta.
The Fraser Valley is expected to reach “heat warning criteria” with daytime highs close to 34 C and an overnight low in the high teens.
The remaining regions can expect daytime highs in the low 30s C and overnight lows also in the low to mid-teens.
With hotter weather, Environment Canada is reminding residents that the risk of heat-related illness increases.
Environment Canada said there will be some relief next week as temperatures are expected to return to near normal.
Meanwhile, warmer temperatures also mean an increase in snowmelt, snowpack instability and stream flows due to run-off.
Although heat is expected, bodies of water are still cool for this time of year and may pose a risk of hypothermia.
