Deep Arctic Storm
1200 UTC Aug 06 2012 Analysis Courtesy of Environment Canada
A remarkably deep storm for the high Arctic brushed Alaska's North Slope Sunday and early Monday. To the right is the Monday 4am ADT (Aug 06 1200 UTC) analysis from Environment Canada, with a minimum sea level pressure of 964mb. Part of the reason for the extraordinarily low pressure was that very warm, moist air from Siberia, yes Siberia, was feed into the system as it developed over the East Siberian Sea on Saturday. The storm was too far north to do much for sea ice transport close to Alaska.
