Heavy rain expected to cause significant snowmelt
It’s going to be wet and mild in much of western Newfoundland this weekend.
Environment Canada updated its weather alerts for the region to a rainfall warning Thursday.
Temperatures for the Corner Brook vicinity are forecast to reach highs of between 7C today and 10 C Saturday, with as much as 70 millimetres of rain to fall during those two days.
The rainfall warning issued Thursday afternoon stretches from the Bay St. George area through the Corner Brook and Gros Morne vicinities all the way northward to the Hawkes Bay area. It stated there could be as much as 100 millimetres of rain in the region’s mountains and that frozen ground will not be able to absorb the rainfall quickly.
Many areas across the island will experience substantial snowmelt, starting today as temperatures rise above freezing. There will be increased risks of flash flooding and water pooling with the thawing snow and rainfall combination.
A special weather statement was issued for the Northern and Baie Verte Peninsulas, where a prolonged period of freezing precipitation appears likely behind the front.
The temperatures are expected to start cooling off Saturday and precipitation ease off Saturday evening. Temperatures will dip back down below freezing Saturday evening.
