Rainfall warning issued for Lower Mainland as BC communities grapple with flooding

Vancouver –

According to a new weather warning from Environment and Climate Change Canada, parts of the Lower Continent could be flooded with up to 120 mm of rain by Sunday afternoon.

That rainfall would be accompanied by snow melt in the mountains which could increase the risk of flooding and potentially affect “vulnerable landscape and infrastructure”, the weather agency said early in the morning. Saturday.

The heaviest rain is forecast to come on Saturday night, as another front approaches BC’s South Coast. The Canadian environment is expected to be around 60 mm in Vancouver, 80 mm in the Fraser Valley and 100 mm or more closer to the mountains. According to forecasts, Squamish can see up to 120 mm.

“Downpours can cause flash flooding and standing water on roads. Local flooding in low-lying areas is possible. Watch out for possible washout near rivers, creeks and sewers.” Environment and Climate Change Canada said in a 4:23 a.m. warning.

The BC government announced Friday that it is proactively closing some major motorways on Saturday because of concerns about an upcoming storm.

The Department of Transportation and Infrastructure said the closures would affect Highway 3 between Hope and Princeton, Highway 99 between Pemberton and Lillooet, and Highway 1 in Fraser Canyon.

The department did not confirm when the highways would close, but asked motorists to check DriveBC for updates.

Transport Secretary Rob Fleming urged British Columbians to avoid non-essential travel, noting the “increased risk of landslides” this weekend.

Last week’s historic storm is estimated to have damaged or destroyed about 200 different points along the province’s highways.

Communities that suffered severe flooding during that weather event have endured several days of rainfall this weekend. Abbotsford Mayor Henry Braun, whose city is estimated to have suffered $1 billion in damage, said officials “remain very concerned” even though work has been completed to keep the Barrowtown Pumping Station running.

The main part of the levee that broke last week, which carries water from the Sumas River into the Sumas grasslands, has been repaired and crews are working to raise another seven kilometers of the dyke along the river.
