Metro Vancouver - North Shore including West Vancouver and North Vancouver
Metro Vancouver - northeast including Coquitlam and Maple Ridge
Metro Vancouver - southeast including Surrey and Langley

Rainfall up to 100 mm for Metro Vancouver, western Fraser Valley and parts of the Sunshine Coast, and up to 150 mm for Howe Sound and the eastern Fraser Valley for Sunday and Monday. Warm temperatures will accompany the rain.

Timespan: Tonight to Monday.

Locations: Metro Vancouver - Central, Metro Vancouver - North Shore, Metro Vancouver - Northeast, Metro Vancouver - Southeast, Fraser Valley, Howe Sound, Sunshine Coast - Gibsons to Earls Cove.

Hazard: 100 to 150 mm of rain. Rising freezing levels with melting snow giving rise to increased river flows and localised flooding.

Remarks: A significant atmospheric river event will bring copious amounts of rain and near record temperatures to the B.C. south coast beginning this afternoon. As the warm front approaches, steady rain will develop this afternoon.

The rain will be heaviest Sunday afternoon and Sunday night ahead of the cold front. The heavy rain will ease on Monday as the cold front pushes the precipitation out of the region.

The lowlands of Metro Vancouver will see up to 75 mm of rain by Monday while the North Shore, Northeast sector including Coquitlam and Maple Ridge and Fraser Valley - West including Abbotsford could see up to 100 mm. Howe Sound and central and eastern Fraser Valley including Chilliwack and Hope could see upwards of 150 mm.

This could result in possible washouts, debris flow and pooling water as rising freezing levels will also melt snow at higher elevations. Local river levels will rise and river flows will increase as a result of the heavy rain.

Near record temperatures will also accompany this system.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts.

4:07 PM PDT Monday 11 April 2022
Snowfall warning in effect for:

Metro Vancouver - northeast including Coquitlam and Maple Ridge
Highly variable but impactful snowfall expected.

Where: Higher elevations of Coquitlam, Port Coquitlam, Anmore.

When: Tuesday, particularly during the morning commute.

Hazards: Localised areas of 5 cm of snow.

Other hazards: Sudden reduction in visibility due to snow, rapidly accumulating snow over higher terrain.

Remarks: The south coast remains under the influence of a cold and unstable airmass. A low pressure system offshore will draw in moisture resulting in convective flurries similar to Sunday's weather across the Lower Mainland. While snow is possible even down to sea level, the higher elevations are more likely to see accumulating snow.

The snowfall accumulation will be highly variable and dependent on precipitation rate, and surface and air temperature. Current forecast guidance suggests the potential for near 5 cm of snow.

Please allow for extra time for your morning commute as travel delays are possible.

Be prepared to adjust your driving with changing road conditions. Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.

Wintry mix of precipitation followed by strong outflow winds, cold temperatures and wind chill this weekend.

Where: Metro Vancouver, Fraser Valley, Howe Sound, Whistler, and Sea to Sky - Squamish to Whistler.

Hazard: Prepare for potentially challenging travel conditions. Check water pipes during the cold period.

Remarks: A series of weather systems will bring periods of snow to the south coast this weekend.

On Saturday, precipitation will fall as light flurries or showers depending on temperature and elevation. In general, 2 up to 4 cm of snow can be expected across the region. For Metro Vancouver, snowfall accumulations are mainly expected over higher terrain.

Saturday night through Sunday, an arctic front from interior BC will move across the south coast and bring a period of heavy flurries to the region. Currently, there is still large uncertainty associated with the timing of this system. Recent model guidance indicates total snowfall amounts near 10 cm are likely for the Fraser Valley, Howe Sound, Whistler, and the Sea to Sky highway. Near 5 cm of snow are possible over Metro Vancouver.

With the passage of the arctic front on Sunday, strong outflow winds will bring in cold arctic air and temperatures falling 5 to 10 degrees below seasonal average.

Please stay tuned to the updated weather forecast and warnings this weekend, and be prepared for changing road conditions and cold temperatures.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to BCstorm@ec.gc.ca or tweet reports using #BCStorm.
