The latest in a series of storms is bringing more wet weather to the West Coast through Wednesday night.

"Unsettled weather will continue across the West Coast this week as more rain and mountain snow targets Northern California, Oregon and Washington," according to AccuWeather Meteorologist Max Vido.

Following a relatively pleasant Tuesday with just some lingering showers in the Northwest, stormier conditions that began early Wednesday in some areas will linger into Wednesday night.

Rain will pick up over much of the region, mainly over coastal areas of Northern California, southwestern Oregon and in the foothills of the Sierra. Flooding will be possible, as many areas have already exceeded their normal rainfall for the month.

"Rainfall amounts could total close to 6 inches in the coastal ranges and foothills of the Sierras," Vido warned.

Outdoor events will need to be rescheduled or moved indoors, and slowed traffic is likely as water ponds on roadways and visibility decreases in times of heavy rain.

Travel delays are likely as isolated flash flooding and mudslides threaten to block or wash out roadways.

Flight delays can also mount as visibility decreases in times of heavy rain - thunderstorms with lightning and small hail are possible throughout the San Joaquin Valley.

Snow is again expected across the higher terrain, with feet of accumulation possible over the Sierras.

"Throughout this period of storminess, snow levels will average from 4,000-5,000 feet in Oregon to around 5,000-6,000 feet across the central Sierras in California," Vido said. Passes at these levels will face deteriorating conditions as roads become slick and snow covered, and travel restrictions or closures become necessary over Donner Pass.

Ski resorts will need to be ready to dig out from another heavy snowfall event, further ensuring that closing dates will be pushed deeper into the summer months with the incredible available snowpack.
