40-Foot Waves, Cat 3 Pressure in Gulf of Alaska
Here are buoy graphs of the high waves, winds, and low pressure over the Gulf of Alaska. The large low pressure system there has been basically stationary for the last day, causing extended periods of terrifying waves and winds.
Looking at the data from buoys in the Gulf, station 46082 recorded the highest winds that I could find with the storm (60 knots)...
...and also had waves of nearly 30 feet for 5 hours yesterday, above 10 feet for 48 hours...
Station 46036 reported the highest waves so far from any buoy that I could find, at 32 feet overnight. Station 46085 had the lowest pressure reading at 27.91" Hg (only 0.03" away from the Category 4 Hurricane classification on the old SS Scale!)
The WaveWatch computer forecast model says that waves over 42 feet could build over the Gulf, with 30-foot waves near the shore of British Columbia today, but high waves will fade from north to south over the weekend.
For the storm's affect on land, consult our Canadian Blog (which says that as much as half a foot of rain and over 3 feet of snow could fall) or this news story about how it will affect the Pacific Northwest U.S.
