Special weather statement in effect for:
- Southern Gulf Islands
The cold outbreak over the South Coast will finally end as mild Pacific air and rain start to move in Monday...
Many south coastal communities have had snow on the ground since December 5 but this is about to change. The persistent blocking ridge over Western Canada that allowed cold Arctic air to settle along the coast will finally start to weaken on Monday. This will allow a series of moist and increasingly mild Pacific storms to move onshore.
Satellite imagery shows a plume of moisture originating near the Philippines streaming towards the BC coast. Rain associated with this plume is expected to begin on Monday and to become heavy at times Monday night. Strong southeast winds will accompany the storms. There is potential for the moderate to heavy rain to continue until Wednesday morning.
Areas along the immediate coast are expected to warm sufficiently so that precipitation begins as cold rain. Inland areas such as Port Alberni, Hope and Squamish could see a period of snow or freezing rain to begin with as mild air moves over the entrenched cold air. Further inland in Whistler and along the Sea to Sky highway, precipitation will start as snow and slowly transition to rain Monday night or early Tuesday.
Stay tuned to the weather as warnings for many areas are likely to be issued.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to firstname.lastname@example.org or tweet reports to #BCStorm.
