You've heard of the calm before the storm, but it's quite evident we are in the storm before the calm in Metro Vancouver Monday, as the region grapples with another day of heavy rains and the addition of possible strong winds.
A rainfall warning remains in effect across the Lower Mainland today (Nov. 15), with rainfall totals of 140 to 180 mm expected in Metro Vancouver, western Fraser Valley, Whistler, Howe Sound and parts of the Sunshine Coast, according to Environment Canada's rainfall warning.
The Fraser Valley, though, is going to get the most significant soaking, with a total rainfall up to 250 mm for central and eastern Fraser Valley by this afternoon.
The national weather agency explains the region is experiencing a continuing "atmospheric river event" which is bringing "copious amounts of rain" to British Columbia's south coast Monday.
Heavy rain will continue this morning and ease this afternoon as the system moves inland.
Additionally, gusty winds are in the forecast, prompting a wind warning from Environment Canada, which indicates the strongest gusts will land nearest the water, and could hit 70 to 80 km per hour, and even up to 90 km per hour closest to the water.
The wind warning is in effect for the following Metro Vancouver areas:
- central including the City of Vancouver Burnaby and New Westminster
- North Shore including West Vancouver and North Vancouver
- southeast including Surrey and Langley
- southwest including Richmond and Delta
The strong northwest winds are expected near noon and through this afternoon.
For areas away from the water, gusty winds are still possible but are not expected to be as strong. Winds will ease early this evening as the frontal system moves further inland.
The combination of rain and wind means Metro Vancouver residents should be aware of the risk of flash floods, washouts, and localized flood in low-lying areas, as well as power outages, downed trees and limbs and changing road conditions caused by high winds.
This week's Metro Vancouver weather forecast
Once this "atmospheric river" flows on by Metro Vancouver, the region can expect a dry couple of days with sunshine, although temps will be lower by a couple of degrees. Tuesday's forecast calls for sunshine and a high of 7 C, which is currently due for a repeat on Friday. In between, some clouds Wednesday, and on Thursday some showers. Right now the weekend is shaping up to feature more of the wet stuff.
