The River Forecast Centre has issued a flood watch for Howe Sound, including tributaries around Squamish. Flood watch means that river levels are rising and will approach or may exceed bank full.
It is also in effect for North Shore Mountains, Sunshine Coast, Central Vancouver Island, East Vancouver Island, and south Vancouver Island. River levels are rising and will approach or may exceed bankfull, cautions the River Forecast Centre, and flooding of areas close to rivers may occur.
A rainfall warning remains is in effect for Squamish, with rainfall total of up to 100 mm.
Rivers are expected to rise through Thursday, with current peak levels expected on Friday and Saturday. Weather forecasts currently have the heaviest rainfall in forecast for North Shore Mountains and Howe Sound area.
Higher rainfall amounts are forecast over higher terrain. Temperatures are also rising, which will also contribute to additional runoff from snowmelt at mid-elevations. Overbank flooding is possible in some areas, the centre adds.
