FREDERICK, Md. -- Frederick County officials warned residents to remain on high alert as heavy rain and flooding continues to impact the area.

The county is in a state of emergency after 9-10 inches of rain have fallen within the past two days. Officials said the flooding and heavy rain has caused damage and closures throughout the area and remind residents that "this is a serious issue and everybody needs to be mindful." Residents are being urged to minimize water usage because of the state of emergency.

LIVE RADAR

Frederick emergency crews have responded to 37 water rescues as of Thursday afternoon. Two of those rescues happened in close proximity early Thursday morning when two people got trapped inside of their cars in high water in the area of Willowbrook Rd. and Willow Rd. In one of the cases crews had to use a boat to rescue the person. Both people were successfully brought to safety with no injuries within 30 minutes.

" We are very fortunate to not have experienced any loss of life," a Frederick County executive said during a Thursday afternoon press conference.

In addition to water rescues, emergency crews have been dealing with several closures triggered by the water damage and flooding. For the second day straight, MARC trains on the Brunswick line have not been operating due to track damage. This will continue to be an issue for commuters until Monday, officials confirmed.
