Deep Storm in the Gulf of Alaska

A fairly deep storm for August is churning through the northern Gulf of Alaska. The 330pm ADT GOES infrared image shows a classic cloud structure to the system, with well defined warm, cold and occluded fronts. Unlike most Gulf storms, this one is forecast by all the numerical models to maintain fairly deep pressures as it crosses the Alaska Range on Saturday. In fact, Fairbanks will approach its lowest August sea-level pressure of record on Saturday of 980.9 mb (28.97 inches) set August 5, 1984.
