All Howard County Public School System after-school events scheduled for Tuesday, including high school athletic practices, games and Back to School Night, have been canceled due to inclement weather, according to a news release.
Activities have been canceled out of concern for the safety of students, staff and community, the release from the school system said.
The National Weather Service had placed a severe thunderstorm warning and tornado watch in affect for much of the mid-Atlantic, including Howard County.
Both the tornado watch and thunderstorm warning have been canceled.
The release added all childcare programs sponsored by the Columbia Association and the Department of Recreation & Parks in Howard County public schools will remain open.
County spokeswoman Karen Spicer said county officials are "monitoring the situation and are prepared to deploy county resources if they are needed."
