There is a rainfall warning in effect for West Vancouver Island, with heavy rain expected through to Thursday morning.
- Rainfall amounts: 125 to 150 mm of rain.
- Timespan: Late this morning to Thursday morning.
- Locations: West Vancouver Island.
- Hazard: Rising freezing levels with melting snow giving rise to high stream flows and localized flooding.
A strong southwest flow will develop today and result in an atmospheric river embedded with a series of systems aimed towards the south coast. Heavy rain will develop late this morning as the first system arrives and continue until Thursday morning as additional systems impact the coast.
Snow levels will rise from 1500 to 2000 metres today and then up to 2500 metres on Wednesday. Some snowmelt over more inland sections will contribute to runoff which may result in high stream levels and localized flooding.
Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.
