There have been at least four deaths due to the storm.

A man shoveling snow in Prince George’s County died of a heart attack as well as another man in Abingdon. Two others also died in Harford County during the storm, but their cause of death has not yet been determined.

Many, not all, of the roads closed overnight Saturday have reopened.

That being said, Gov.Larry Hogan is still asking residents to stay off the roads to allow for crews to clear roadways. He’s also asking for patience.

“This really is a significant storm,” said Hogan.”Sometimes you get the false alarm and people don’t prepare as they should. This is a serious snow event. People are going to have to get home, get supplies up to a week.”

“We want them look out for their neighbors. People that are elderly or they go medical issues. Make sure you got your pets inside,” he said.

We’re urging them to be patient because we’re not magicians — we can’t make it disappear. The local governments will work as hard as they can,” Hogan added.
