Brisk northeast wind gusts above 60 mph began at the Wasilla Fire Station between 3:15 and 3:30 pm Wednesday. Modified arctic air flowing out of the Copper River Basin...associated with strong high pressure in the Northwest Territories of Canada...was the cause of the winds. Peak gusts reached 70 mph between 5 and 5:30 pm Wednesday, with gusts diminishing below 60 mph by 8:30 pm.
