...A POTENTIAL HURRICANE FORCE LOW PRESSURE SYSTEM TO AFFECT THE
BERING SEA THURSDAY/FRIDAY...

A major low will continue northeastward today and move into the
Bering Sea tonight into Thursday. The storm will rapidly deepen
as it approaches the Pribilof Islands. The models suggest that
this low will deepen 30 mb to 27 mb in 24 hours. This will
support widespread storm force winds around the system, with an
opportunity for hurricane force winds, especially on the backside
of the system where arctic air is wrapping southward. Seas could
rapidly build into the 35-50 ft range where the strongest winds
develop. Expect the strongest winds and highest seas to develop
Thursday afternoon and continue into Friday morning.
