Not a time to be in Alaska. From Cliff Mass:
A Superstorm of Tropical Origin Will Develop Off the Northwest Coast on Thursday
I have been watching this storm for a while, and I am now certain enough to tell you about it.
A powerful, unusually deep storm will develop off the Northwest coast on Thursday.
A mid-latitude cyclone that began as a tropical storm (Namtheun), now over the western Pacific.
Below is the 96-hour forecast valid at 5 AM Thursday (PDT) of sea level pressure from the U.S. NOAA/GFS model. The solid lines are isobars (lines of constant sea level pressure).
Amazing...the storm, located due west of our coast, has a central pressure is 952 hPa, which is very, very low for a mid-latitude cyclones at our latitude.
This storm is deeper (lower pressure) than the extreme Columbus Day storm of October 12, 1962--the greatest storm to hit the Northwest in 100 years or more.
Lots more at the site. Fortunately for us, it will hit further North - Alaska and Northern Vancouver Island and British Columbia. Still... Something to keep a weather-eye out for.
