AWIPS images of Suomi NPP VIIRS 0.64 µm visible channel data (above) and 11.45 µm IR channel data (below) showed a close-up view of the clouds associated with a strong storm (surface analysis) that was crossing the Aleutian Islands and entering the Bering Sea on 03 September – 04 September 2012. Banded convective elements can be seen along the western edge of the high cloud deck, which marked the leading edge of the advancing occluded frontal boundary.

At the time of the images, the winds at Shemya Air Force Base (station identifier PASY) were gusting to 57 knots (66 mph), but during the previous hour the peak winds were 61 knots (70 mph).
