Barrage of storms to aim for US West Coast next week

Topic driven playlist

Several storms will bring periods of rain and gusty winds to the west coast of the United States next week with the potential for one of these to reach Southern California.

"Several storms will spin off the northwestern United States coast bringing rounds of rain, heavy at times, from northern California to Washington," AccuWeather Senior Meteorologist Mike LeSeney said.

While a weak storm will bring some rain to western portions of Washington and Oregon this weekend, the stronger storms won't arrive until early next week.

The first storm will spin off the Pacific Northwest Coast from Sunday night through Monday. A second, weaker storm will track up the coast during Tuesday night and Wednesday.

Occasional rain will slow travel from Seattle to Portland, Oregon and Crescent City, California.

The heaviest rain is expected to fall across northwestern California. Rainfall may total up to 6 inches by the middle of the week.

A general 1-3 inches of rain will fall across locations west of the Interstate-5 corridor in Washington and Oregon.

Some of this rain will reach portions of central California, including San Francisco, though amounts will be much lower compared to locations farther north.

Little to no rain will reach Southern California through Wednesday.

Windy conditions will stretch across the Washington and Oregon coasts at times.

"Winds will occasionally gust between 40 and 50 mph along the Washington and Oregon coasts as well as in the coastal mountains of southern Oregon and northern California," LeSeney said.

The combination of a saturated ground and strong wind gusts could topple trees and knock down power lines resulting in sporadic power outages.

The higher elevations of the Cascades will be cold enough for some accumulating snow. Snow levels will dip to 7,000 feet on Monday, but rise to near 8,000 feet during Tuesday and Wednesday.

The snow will give a boost to ski resorts prior to the start of the winter season.

None of these storms are predicted to impact the area as severely as the powerful storm on Oct. 13-14.

Motorists should be on alert for ponding of water on roadways and flash flooding in low-lying areas.

The multiple rounds of rain will continue to increase monthly rainfall surpluses throughout the Pacific Northwest.

Drought concerns throughout the region have been virtually erased as some locations have already picked up nearly four times their normal monthly October rainfall totals.

By the end of the week, drier weather may build across the Pacific Northwest as a new storm may dive far enough south to bring locally heavy rainfall to much of central and Southern California.
