- Showers and thunderstorms will continue today. Rain may be
heavy at times, with the strongest storms capable of
torrential rainfall which could drop up to 2 inches of rain
in just an hour's time in the hardest hit areas. Soil
moisture is already quite high and stream flows elevated, so
heavy rainfall could quickly result in flash flooding of
streams, creeks, low lying, and flood prone areas.
