ISSUED: 1:00 PM February 1, 2020
The River Forecast Centre is issuing a Flood Watch for Central Vancouver Island including:
- The Ash River, Sproat River and Somass River
- Port Alberni
An atmospheric river event has causing heavy precipitation for Vancouver Island and about 100mm of total rainfall for Central Vancouver Island on Friday. The Ash River, Sproat River and Somass River have risen rapidly last night and are currently running at flows between the 2 and 5-year return periods.
Based on the latest updated hydrologic modeling, the flows in the Ash River and Sproat River are expected to rise to the 5-year return period flows. The estimated flow for the location of the inactive Water Survey of Canada’s station, the SOMASS RIVER NEAR ALBERNI (08HB017), is expected to peak at about 900 m3/s, which is a flow about the 5-year return period, tonight or tomorrow morning.
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-river-level period.
The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.
