Wet West Coast

Wet times are ahead for California, Oregon, and Washington. A potent low will interact with more-than-adequate moisture to create heavy precipitation across parts of California late Thursday into the weekend. The rich moisture is ‘streaming’ off of the central-Pacific, which is sometimes coined the “Pineapple Express” in meteorology. The heavy precipitation may cause flash flooding and mudslides in California with more moderate amounts further north into Oregon and Washington.

Much of northern and central California is under Flood Watches from the National Weather Service from late this week into the weekend.

Latest From The National Weather Service
This area can expect widespread 2-4″ amounts of rain with areas in the middle and higher terrain seeing 4-8″ amounts. Isolated 8-14″ rainfall totals are possible. Most of the precipitation will remain liquid; however, above 9,500′ will likely see very heavy wet snow.

Oregon and Washington will get in on the action, too. As a strong low approaches the coast, surface winds may exceed 50mph at times.
