| The big picture Monday morning |
Be prepared for a very wet next 72 hrs, a series of powerful pacific frontal systems are set to approach the coast with up to 200mm of precipitation. A strong upper level jet stream will help pull in some very warm air from the south southwest. Freezing levels are expected to be above 2000m for the first 3 systems and gradually drop in behind the 3rd system on Thursday night when a 4th slightly cooler system arrives. The wind will also be out in force as the systems are expected to generate high southerly winds at ridge top exceeding 100km/ph

Rainfall warning in effect for:
Howe Sound
Heavy rain is expected.
An incredible series of storms are set to cross the BC Coast this week. An intense jet stream over the Pacific is gathering very warm moist air from southern latitudes. A subtropically-influenced airstream will bombard the mountains of Vancouver Island and the Lower Mainland from today through Thursday morning.
The first two storms will boost rainfall totals well above the warning criteria for a 24-hour period. Following systems will add to the week's rainfall and the initial warnings will likely be extended for successive 24-hour periods though mid-week. The inflooding warm air will drive the freezing level to nearly 2500 metres. In some areas, additional water from snow-melt will add even more water to drainage basins, creeks, and rivers.
The West Coast of Vancouver Island, Inland areas including Port Alberni and Howe Sound will absorb the brunt of the saturated airstream. Rainfall totals in the range of 100 to 200 millimetres are expected through Tuesday morning, And that will be just the beginning...
Heavy downpours are likely to cause flash floods and water pooling on roads. Don't approach washouts near rivers, creeks and culverts.
