An abbreviated flash flood/flood climatology (1994-2007) for the WFO Blacksburg, Virginia County warning area
Filetype[PDF-1.93 MB]

  • Description:
    WFO Blacksburg first opened in 1994 as part of the National Weather Service modernization. With modernization, there was an increased emphasis on verification for Storm Data, published by the National Climatic Data Center (NCDC). Fourteen years of flood event data from 1994 to 2007 for the WFO Blacksburg County Warning Area (CWA) were studied. Each flood event listed in a county with a unique time and date was counted as a separate event. The data consisted of 1168 events, which were categorized as a flash flood, areal flood or river flood. The impact description in Storm Data for each event was used to stratify all of the events by the severity of flooding. The date, time, location and severity of each event was then used to develop a short term climatology of the flooding in the WFO Blacksburg CWA during the 14 year period. The purpose of the study is to provide forecasters with an improved understanding of the frequency, severity and geographical distribution of seasonal and diurnal flood events across the CWA.
