At the request of Howard County government, the National Weather Service Baltimore/Washington Weather Forecast Office will issue a TEST Flash Flood Warning for Ellicott City around 9:30am. This will allow Howard County MD government to test their alerting systems in Ellicott City. There is no flooding in the area.


Since this is a test warning, it should NOT alert cell phones or NOAA weather radios.


Further information from the county is available on the Ellicott City Safe and Sound page here.
