Precipitation Fire Hose to Aim Rain, Snow at British Columbia, Northwestern US

A fire hose of precipitation will take aim late this week at British Columbia and the northwestern United States.

It will be the finale of a two-round event that brought snow and rain to the region earlier in the week.

A vigorous jet stream will pull moisture from the western Pacific into the region, starting Thursday through Saturday.

Heavy snow, flooding downpours and strong winds are all possible as a result of the second storm. Up to 300 mm (12 inches) of rain are possible from the central British Columbia coast down into parts of western Washington.

"It is the beginning of the rainy season but rainfall for much of western Washington has been above average over the past two weeks," AccuWeather Meteorologist Mike Doll said. "This next series of storms will raise the risk for not only street flooding but flooding on area streams and rivers. Snow levels will be high enough that snow melt will add to water runoff."

Southerly winds could gust to 90-100 km/h (56-62 mph) along the British Columbia coast and in the coastal mountains Thursday into early Friday, AccuWeather Canadian Weather Expert Brett Anderson said.
