The Frederick County Division of Emergency Management urges residents and business to prepare now for heavy rains leading to flash flooding.
According to the National Weather Service, a cold front sliding east will interact with subtropical moisture and bring the potential for three to five inches of rain over the next 24-48 hrs. The heaviest period of rain is expected late Wednesday night through Thursday afternoon. Potential exists for flash flooding of streams, creeks and urban areas.
Urban flash flooding can occur with little or no warning due to the large number of paved surfaces across urban areas. These surfaces do not allow rainwater to be absorbed into the ground and can result in storm drains being overwhelmed during periods of heavy rain, causing localized flooding.
Take steps now to prevent flooding at home or businesses, especially if you have areas susceptible to flooding such as basement doors or below street level entrances.
