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. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers are possible. Area creeks and streams are running high and could flood with more heavy rain. * ADDITIONAL DETAILS... - An additional 3 to 6 inches of rain is expected to fall today through Friday evening.
