The tranquil weather along the West Coast is coming to an abrupt end Wednesday, leading to a stretch of drenching and powerful storms.
As the first storm in a series pushes eastward, residents from Los Angeles to Portland will need the umbrella on Wednesday.
After a brief break on Wednesday night, a soaker of a day is in store for Thursday, especially along the coast.
Enough rain will fall into the weekend to bring flash, urban and small stream flooding.
It has been a rather wet and stormy month of November in many places from San Francisco to Seattle. Most locations are at or above their normal precipitation for the month and more rain is on the way.
High pressure in control of the weather over the past several days has led to a return of dry, sunnier weather, but a potent storm system lurks off the coast.
The persistent flow of storms is expected to continue into the weekend with the heaviest precipitation focused in northern California.
According to Western Weather Expert Ken Clark, "Some of the mountains in northern California can receive over a foot of rain."
Rainfall of this magnitude can lead to serious problems including mudslides and debris flows in recent burn areas to flooding along some small rivers.
With the flow off the Pacific and a lack of cold air to the north, snow levels will remain above pass level. While snowfall will be lacking in many places, the rainfall will not. Flooding can occur in places, especially the Sacramento Valley.
As with most strong storms from the Pacific Ocean, wind will be an issue along the immediate coast from northern California to Washington and British Columbia. Wind gusts can peak over 75 mph (hurricane force) by Wednesday night and Thursday.
The weather pattern will not become less stormy until early next week, however less intense storms will still move ashore in the Northwest.
