The special weather statement about heat has been issued for the majority of the province.

It says although daytime highs could well exceed seasonal averages, overnight temperatures are expected to drop into the teens for most regions.

Environment Canada is asking people to watch out for heat-related illness.

As temperatures in the low to mid-30 C arrive, the River Forecast Centre saysit's uncertain how the conditions could affect snowmelt and raiseriver levels, but warns unsettled weather and thunderstorms areforecast next week, bringing additional flood risks.

Environment Canada says increased stream flows due to run-off are "probable."

Severe thunderstorm warning
