The State Highway Administration is warning drivers to be cautious in the afternoon rush hour. SHA crews will not be able to apply salt brine to the roads before any snow because the storm will likely start as rain.
“Many commuters, especially south of Baltimore, should get into work with little difficulty, but may experience wintry conditions by Thursday afternoon’s rush hour. Each of us needs to assume the worst and have a plan,” SHA administrator Melinda B. Peters said in a press release. “Storms during afternoon rush hours pose certain challenges because SHA snow plows are driving in rush hour traffic, making snow clearing more difficult. If the forecast calls for snow during any commute and you want to avoid hours of traffic congestion, it is best to leave early, telecommute or stay late until the snow stops.”
