IMPACTS…Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks.
ADDITIONAL DETAILS…Current streamflow is near normal, but excessive rain combined with saturated ground will lead to higher-than-normal runoff.
