    - POTENTIAL IMPACTS: Significant
        - Moderate rainfall flooding may prompt several evacuations
          and rescues.
        - Rivers and streams may quickly become swollen with swifter
          currents and may overspill their banks in a few places,
          especially in usually vulnerable spots. Small streams,
          creeks, canals, and ditches may overflow.
        - Flood waters can enter some structures or weaken
          foundations. Several places may experience expanded areas
          of rapid inundation at underpasses, low lying spots, and
          poor drainage areas. Some streets and parking lots take on
          moving water as storm drains and retention ponds overflow.
          Driving conditions become hazardous. Some road and bridge
          closures.

* TORNADO
