Rainfall warning in effect for:

Fraser Valley - central including Chilliwack

Fraser Valley - east including Hope

Rain, at times heavy, is expected.



Heavy rainfall will continue over Howe Sound and Metro Vancouver today, and will spread to the Fraser Valley tonight. This moisture-laden system will deliver 40-70 mm of rain by Thursday morning.



Rainfall rates will lessen on Thursday but persistent moist, onshore flow will cause showers, heavy at times, to continue Thursday. The heaviest rain amounts are expected near the mountains and eastern sections of the Fraser Valley.

Heavy downpours can cause flash floods and water pooling on roads. Watch for possible washouts near rivers, creeks and culverts.



Rainfall warnings are issued when significant rainfall is expected.

Statements

12:09 PM PDT Wednesday 23 September 2020

Special weather statement in effect for:

Fraser Valley - central including Chilliwack

Fraser Valley - east including Hope

Fraser Valley - west including Abbotsford

Today's heavy rainfall is the first storm in a week-long series that brings a major pattern change to the province of BC, in particular the south coast. Periods of rain, heavy at times, will continue through Saturday. Embedded thunderstorms and gusty winds are possible.



This sudden change to a prolonged wet pattern combined with local gusty winds and trees shedding their leaves may lead to localized flooding. Strong winds may also lead to power outages.



Late this week the pattern is intensified once again by a strong low pressure system crossing Vancouver Island Thursday night or Friday. Strong winds, and where they materialize, will depend on the exact storm track. Stay tuned to your local forecast throughout the week as we follow the evolution of this feature.
