Rainfall rates elsewhere have been between .25-.50 inch per hour.

Local rates near thunderstorms could be up to one inch per hour.

The heavy rain is anticipated to cause roadway and small stream flooding.

Precautionary/Preparedness Actions include:

  • Be especially cautious at night when it is harder to recognize the

dangers of flooding.

  • Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other drainage areas and low lying spots.
