Special Weather Statement

▶

4:49 a.m. PDT Sunday 15 March 2026

Prolonged atmospheric river event.

When:
-Today to Wednesday morning

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 begin to make landfall over the BC coast today and will remain over the region until Wednesday bringing heavy rain. The rain could be mixed with snow today as the freezing levels will be near sea level, but the freezing levels will quickly rise tonight and reach 2500 to 3000 metres on Monday morning. The heaviest rainfall is expected on Monday and Monday night.

Although there is still uncertainty regarding rainfall amounts associated with this atmospheric river, total rainfall amounts could reach 80 to 120 mm for Inland Vancouver Island.

The rain will ease on Wednesday morning.

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.
