First Fall-like Pacific Storm To Bring Biggest West Coast Rains In Months!

Written by on September 23, 2014 in United States of America with 0 Comments

For the best part of a year, high pressure has dominated much of the eastern Pacific and Western North America thanks to warmer than normal SST’s and it’s been one of, if not thee driest year’s on record for California. The abnormally dry conditions stretch all the way into Oregon and Washington as well as British Columbia.

We have finally, the first signs of fall on the weather charts as a deep Pacific low has spun up and will drive the first big rains since last spring into the Pacific Northwest reaching down into Northern California over the next 2-4 days.

Beautiful visible satellite view.

ECMWF sea level pressure is down to 974mb within the center of this storm. Pretty impressive for September!

So too are winds. 50 kts to the SE of the center. Should kick up some impressive waves.

Some isolated gusts may top 40 to 50 kts up against the coast and over exposed mountain ridges.

This will be great for all of the Pacific Northwest but especially points further south. Notice the big rains skirting the East Coast too. Will discuss that tomorrow.
