Impact Level: Moderate
Forecast Confidence: High
Rain, at times heavy, is expected.
Prolonged atmospheric river event.
When:
-Now until 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 make landfall over Vancouver Island tonight and will remain over the region until Wednesday bringing heavy rain. The rain could be mixed with snow this evening as the freezing levels will be near sea level, but the freezing levels will quickly rise tonight and reach 2500 to 3000 metres on Monday morning. The heaviest rainfall is expected on Monday and Monday night.
Total rainfall amounts will vary, but between 100 to 150 mm can be expected by Wednesday morning, with the highest amounts forecast over northern sections.
The rain will ease on Wednesday morning.
Water will likely pool on roads and in low-lying areas. Some travel delays are possible. Landslides may occur in vulnerable areas such as steep slopes, deforested areas or recent burn scars. Fast-moving and rapidly rising water can sweep vehicles away and damage infrastructure.
Watch for washouts near rivers, creeks and culverts.
