Environment Canada has issued a couple of weather warnings for Haida Gwaii, the North Coast, and some inland areas.
Kitimat is under a heavy rainfall warning as a significant storm is expected to make its way into the North Coast Sunday with strong wind and heavy downpours.
As the weather system tracks over northwestern Haida Gwaii Sunday afternoon and moves onto the Alaska Panhandle by evening, the associated cold front will likely proceed over the Central Coast tonight.
Rainfall amounts of between 40 to 60 mm are expected in the Kitimat region by Monday morning.
Environment Canada says heavy downpours can cause flash floods and leave water pooling on roads.
Forecasters have also issued a special weather statement for Haida Gwaii, coastal sections of the North and Central Coasts, and inland sections of the North Coast, including Terrace.
Environment Canada says to expect wind of up to 80 km/h over exposed coastal areas ahead of the system and shift to southwest later this afternoon over Haida Gwaii.
Heavy rain will continue on the North Coast until early Sunday evening and reach the Central Coast by nightfall as the cold front arrives.
Rainfall amounts through Monday morning are expected to be near 50 mm except 70 to 100 mm for the Central Coast.
