May 2013 Oklahoma tornadoes and flash flooding

Filetype[PDF-1.22 MB]


  • NOAA Program & Office:
  • Description:
    "From May 19 to May 31, 2013, a series of devastating weather events affected the area in and around Oklahoma City. Although this report focuses on three specific days, May 19, 20, and 31, the entire period was characterized by an active weather pattern and multiple tornadoes across several National Weather Service (NWS) Weather Forecast Offices' (WFO) areas of responsibility. The historic flash flooding that occurred in Oklahoma City on May 31 is also of note. This flash flooding caused more fatalities than the tornadoes on that day. In all, there were 47 direct weather fatalities in the WFO Norman County Warning Area during these 13 days in May. NWS formed a Service Assessment Team to evaluate NWS performance and to undertake a detailed social science review to examine the effectiveness of messaging and the behavior of the public in each severe weather event. The team concentrated its efforts primarily on counties and cities affected by the strongest tornadoes during this period. NWS also conducted a complete review of the operations of WFO Norman and the Storm Prediction Center. After the events on May 20 and May 31, NWS Southern Region Operational Services Division conducted a Rapid Evaluation of Service Activities and Performance (RESAP). Several of the RESAP findings were incorporated into this report."--Executive summary.
