Howard County public schools are closed Tuesday for the second day in a row because of an expected snowstorm.

All evening activities in schools are canceled, both school- and community-sponsored. That includes high school sports practices and games, according to a 4:56 a.m. email from the school system.

A National Weather Service winter storm warning remains in effect until 2 p.m., with predictions of snow, sometimes heavy and sometimes mixed with sleet, starting at daybreak.  NWS estimates an accumulation of 4 to 6 inches. 

Because the heaviest snowfall is likely to coincide with the morning rush hour, State Highway Administration officials urged drivers to delay travel to work until the storm is over. 

The Howard County government is on liberal leave. 

The Howard County Economic Development Authority will be closed. 

Howard County parks and facilities are closed today. All programs are cancelled. 

The Circuit and District courts will be closed. 

Trash and recycling collection is cancelled. All collections will slide and be made one day later this week, officials said. The Alpha Ridge landfill will remain open from 8 a.m. to 4 p.m. 

All Howard County Library System branches are closed. 

The Columbia Association has also announced that its inclement weather policy is in effect, and programs before 10:45 a.m. are canceled, though facilities at this time are opening as normal, according to a 5:35 a.m. tweet.

Howard Community College will be opening at 10 a.m., per an announcement on the school's website.

Because the school system has used two inclement weather days this academic year, the last day of school is expected to be Friday, June 13, 2014.
