4 flash flood. Local standard time, as filed.
General 1 to 2 inch rainfall, with isolated totals to 3 inches, combined with soils that were already saturated, resulted in brief flash flooding from the late afternoon into the early evening.
Numerous roads closed as a general 2 inch rain fell over the county, with up to 5 inches in some parts of the county. County soils had remained very saturated through the past several weeks and that contributed significantly to the flooding.
Brief flash flooding was reported over the county as a result of 1 to 2 inch rainfall over soils that were already soaked. The flooding ended in the early evening.
Several county roads were closed briefly due to flash flooding that resulted from a general 1 to 2 inch rainfall over the already saturated soils.
