Photo of A screen shot of FireBuster 1-km run results showing surface wind speed (in color) and wind vector forecast for the area around Berardo Fire on Aug. 13, 2014 (lower-left of the map), about 5 miles south of Escondido, CA. The map shows 38th hour forecasted weather validated at 7 p.m. Pacific Standard Time, August 14, 2014. Signature Santa Ana wind was from the east and modified by the terrain. The forecasted weather and wind were validated well against those corresponding Remote Automatic Weather Stations of San Pasqual (near center of the map) and Goose Valley (right), respectively, at this particular hour, as well as during the entire 72-hour forecast.
