An arctic outflow warning has been issued for the North Coast. Strong outflow winds and cold windchill values are expected or occurring.
Very cold windchill values near -20 are expected over inland sections of the north coast through Tuesday, as cold arctic air flows out from the interior through the mainland coastal inlets.
The very cold windchill values will probably persist into Wednesday. Limit outdoor activities. Minimize exposed skin with hats, scarves and mittens or gloves.
Adding to the arctic outflow warning, there’s also a wind warning for the Central Coast.
Wind speeds between 80 and 100 km/h near mainland inlets will ease gradually from this afternoon through Tuesday morning.
An Arctic ridge of high pressure over the northern B.C. Interior combined with an area of low pressure west of Vancouver Island is producing very strong northeasterly outflow winds through the mainland valleys and inlets of the Central Coast.
Winds will begin to ease this afternoon as the low weakens. High winds may toss loose objects or cause tree branches to break.
Wind warnings are issued when there is a significant risk of damaging winds.
