Additional rainfall up to 0.75 inches is possible, and flash flooding is ongoing or expected to begin shortly.
Life-threatening flash flooding is expected to affect creeks, streams, urban areas, highways, streets, and underpasses.

The National Weather Service urges residents to avoid flooded roads; most flood deaths occur in vehicles. Exercise caution, especially at night when flood dangers are harder to recognize.
