yellow warning - rainfall - in effect
Rain, at times heavy, is expected.
Prolonged atmospheric river event.
When:
This afternoon to Wednesday morning.
Where:
Sunshine Coast, Howe Sound, Metro Vancouver - North Shore and northeast including Coquiltam and Maple Ridge.
Impacts:
-Prolonged heavy rain on snow combined with mountain snow melt will lead to very enhanced responses in river systems and potential for flooding.
-Extensive water pooling on roads and wash-outs may occur.
-Enhanced risk of landslides due to saturation of landscapes.
Remarks:
An atmospheric river will push into the B.C. South Coast beginning later today and remaining over the region until Wednesday morning bringing prolonged periods of heavy rain. Rainfall totals will vary, but between 100 to 150 mm can be expected by Wednesday morning.
Additionally, the rain could be mixed with snow tonight as freezing levels will initially lower to near sea level. Freezing levels will quickly rise to between 2000 and 2500 metres by Monday morning. Snowmelt from higher elevations will increase the risks from this rainfall event.
###
Water will likely pool on roads and in low-lying areas. Some travel delays are possible. Landslides may occur in vulnerable areas such as steep slopes, deforested areas or recent burn scars.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to BCstorm@ec.gc.ca or post reports on X using #BCStorm.
Don't drive through flooded roadways.
