Prolonged atmospheric river event.
When:
-Sunday morning to Wednesday morning
Impacts:
-Prolonged heavy rain on snow combined with mountain snow melt will lead to very enhanced responses in river systems and potential for flooding.
-Extensive water pooling on roads and wash-outs may occur.
-Enhanced risk of landslides due to saturation of landscapes.
Remarks:
An atmospheric river will begin to make landfall over the BC coast on Sunday and will remain over the region until Wednesday bringing heavy rain. The rain could be mixed with snow on Sunday as the freezing levels will initially lower to near sea level, but the freezing levels will quickly rise on Sunday night and reach 2500 to 3000 metres on Monday morning. The heaviest rainfall is expected on Monday and Tuesday.
Although there is still uncertainty regarding rainfall amounts associated with this atmospheric river, total rainfall amounts could exceed 300 mm for West Vancouver Island and could exceed 150 mm for Inland Vancouver Island, North Vancouver Island and the coastal sections of the Central Coast.
The rain will ease on Wednesday morning.
