Rainfall Warning

Issued at 04:27 Friday 15 October 2021

A long episode of heavy rain is expected.

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

Timespan: Today through Saturday night with a short break this evening.

Threat: 90 to 150 mm of rain with highest amounts expected for Howe Sound and the North Shore.

Remarks: Two successive frontal systems will cross the south coast between today and late Saturday night, with high water content associated with an Atmospheric River flowing off the Pacific Ocean. As freezing levels rise to near 2500 metres, snow melt will also add to the runoff. Swelling of local streams and localised flooding are likely during this time.


Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

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