Nome peak wind was 43 knots (49 mph).Zone 216 - Koyukuk Remote Automated Weather Station (RAWS) peak gust 56 knots (65 mph); Huslia AWOS peak gust 54 knots(62 mph). Also Kaltag ASOS Peak Wind 48 knots (55 mph) and Galena highest gust 34 knots (39 mph). In the village of Nulato, onthe night of the 20th a tree fell onto a power line which pushed the line onto the city building which started a fire, destroying thecity building. The building contained most of the administrative and financial records of the village, along with archives ofirreplaceable documents and photos. Estimated loss is $150,00Zone 220 - Hodzana Remote Automated Weather Station (RAWS) peak gust 54 knots (62 mph). Also Seven Mile RAWS peak gust50 knots (58 mph). Strong winds producing heavy blowing snow over Eagle Summit and Twelvemile Summit of the SteeseHighway forced the Alaska Department of Transportation to close the highway. In addition strong winds and blowing snow werealso reported on portions of the Dalton Highway with Travel Advisories issued.Zone 221 - Pilot on ground at West Twin Lakes estimated wind gusts near 60 mph. The State of Alaska Department ofTransportation posted travel Advisory for the Elliot Highway over the summits due to strong winds and low visibility in blowingsnow.Zone 222 - Caribou Peak Remote Automated Weather Station (RAWS) peak gust 50 knots (58 mph). Also Fairbanks ASOS peakwind 33 knots (38 mph). Winds toppled trees most notably in the North Pole area, where a chain link fence was damaged (estimated$500) from a falling tree, and a minivan was totaled when an 80-foot spruce tree fell onto it (estimated $6500).AKZ207-213AKZ213ALASKA, SoutheastAKZ017Blizzard conditions:Like occurred at Cape Romanzof (Zone 214).

Highest wind gust 46 mph at Point Hope.Zone 213: likely at Tin City.High Winds occurred in zone 213 at Tin City: peak gust 62 knots (71 mph).Cape Fairweather To Cape Suckling Coastal Area10 0500AST0700AST0 0High Wind (G52)High easterly winds along the Northern Gulf Coast from Cape Suckling to Icy Bay. The winds developed out ahead of the frontassociated with a 955 MB Low in the western Gulf of Alaska. No damage nor injuries were reported in this largely uninhabitedstretch of coastline.1620

The offshore, downslope flow and extremely dryatmosphere (dewpoints near zero) combined with sufficiently dry flashy fuels (grasses) near sea level to heighten the wildfiredanger throughout Southeast Alaska. A total of five small grass fires (1 acre or less) were reported in the Haines, Juneau andWrangell areas. No damage nor injuries occurred though our fire departments were called into action for grass fires about monthearlier than normal.Wrn P.W. Snd & Kenai Mtns10110625AST2155AST0 0 20KHigh Wind (G95)An intense low in the Gulf of Alaska pushed a front into the north gulf coast Thursday morning, March 10th. The intense gradientin advance of this front funneled strong wind through Portage Pass and in the Bear Valley area. The wind peaked at a measured 109mph in Bear Valley at the staging area for the Whittier Tunnel. The wind peaked at 81 mph at the Portage ASOS at 11:43 AM AST.Anchorage Muni To Bird Creek12 1300AST0 0High Wind (G74)1630ASTA strong low moved into the Bering Sea Saturday. High pressure over eastern Alaska resulted in a tight pressure gradient acrosssouth central Alaska. The typical channeled gap winds occurred across the Chugach Mountains. The usual observation sites forthese high winds were non-operational. The wind speeds are estimated from the nearby observations and from the surface analysis.Nern P.W. Snd20 0830AST0 0High Wind (G71)21 1122ASTStrong high pressure building over northern and eastern Alaska combined with low pressure in the northern Gulf of Alaska resultedin strong gap outflow wind in northern Prince William Sound. The north wind peaked at 82 mph at the Valdez Airport at 940 am.Matanuska Valley20 1500AST0 0 3KHigh Wind (G70)21 1300ASTStrong high pressure over interior Alaska coupled with an intensifying low in the Gulf of Alaska resulted in strong gap outflowwind through the Chugach Mountains. The wind peaked at 81 mph at the Wasilla airport. The strong wind blew the McDonaldssign down and also knocked trees down in the Palmer-Wasilla area causing localized damage.1721
