A 974 mb low moved southward across the Alaska Peninsula and into the Gulf of Alaska. Behind this low, a 1039 high was centered over the Western Aleutians. This caused a strong gradient with northerly flow over the Pribilof Islands, the eastern Aleutians, and the Alaska Peninsula. This storm strengthened in the Gulf of Alaska and moved onshore in the northern Panhandle. As a result, northerly gap winds intensified over the Prince William Sound.
