Above is a graph of the average and peak wind speed at the NASA Radarsat building just north of town, provided by Jordan Dickens (here is the original spreadsheet). The peak gust recorded here was about 160 mph. This is not the official weather data...but the wind bird at Mac Center blew away at 96 mph, and the one on the lab gave up at 116 mph. Elsewhere around, the peak wind at Arrival Heights was 188.4 mph, and one of the walls developed a crack. Cosray survived except for the wind birds--one blew away at a mere 72 mph while the other lasted up to 170. And at Black Island, the official wind gauge blew away, but the one attached to the comms equipment recorded 157 mph sustained. In any case this may have been the most severe storm in the last 30 years. Similar wind speeds were recorded at Scott Base. Temperatures ranged from +14°F to -9°F during the storm period. The system also affected weather at Pole, bringing peak gusts of 40 mph which is rather significant considering that the peak wind ever recorded at Pole was 55 mph...
Okay, so what did this storm do? Briefly, it blew a lot of snow around, blew in many doors and windows, ripped off roofs and siding, knocked a lot of loose stuff around, and generally made an expensive mess:
