Torrential Rain to Cause Flooding From California to Washington

Extreme rainfall forecast for Northern California and the southwest corner of Oregon the rest of the week and into early next week. High winds accompanying the storm may cause power outages.

Here is a detailed map where flooding is most likely.

On some of the higher peaks, as much as 20 inches of rain is forecast to occur. 

In San Francisco, amounts will be substantial, generally in the 3 to 4 inches range. However, Mount Tam may have more than seven inches by early next week. 

Seattle may have 4 inches or more. And, for the first time this season, Los Angeles will be affected by an atmospheric river but the amounts will only be around a quarter inch with as much as a half-inch in the higher elevations. 

This forecast could be more definitive if the Hurricane Hunter aircraft were available to survey the developing atmospheric river over the eastern Pacific. But, even though zero hurricanes are forecast to occur the rest of hurricane season! See below:

NCEP = NWS's National Center for Environmental Prediction. NOAA controls the airplanes and while I do not know the specifics of this situation, NOAA isn't much interested in day-to-day weather prediction when they can be writing $10 million checks for "environmental education" to unaccountable non-profits. 

If you haven't seen it, please see my plan for the future of the National Weather Service and forward it to your newly elected representatives.
