Snow has begun to accumulate across Maryland and Carroll County this evening, with road conditions already reported hazardous in some areas.

The National Weather Service's latest guidance is that somewhere between 9-13 inches of new snow is expected to fall overnight in the South Carroll area, with another 10-16 inches of snow expected during the day on Saturday.

In addition, winds will pick up in intensity as the storm moves in, creating visibility issues for drivers.

The winds may also cause power outages. To report a power outage to BGE, call 877-778-2222. If you see downed or sparking electric lines, stay as far away as possible and please call 911.

Here is the latest information from the Maryland Emergency Management Agency:

Governor Larry Hogan has signed an executive order declaring a state of emergency in order to activate and coordinate all available State resources. A state of emergency is also an indicator to residents that this will be a significant winter storm and that they should take precautions.

“Now is the time for Marylanders to stay at home and off the roads,” said Governor Larry Hogan. “This is the safe choice. It will also allow emergency services vehicles to maneuver and road crews to begin the long process of clearing highways and streets.”

The Maryland Emergency Management Agency has been coordinating resources in order to manage incidents that could arise due to the storm. This includes working with local officials to mobilize high-clearance vehicles, emergency supplies, and personnel in areas and communities that could be affected most by the storm.

“This heavy, wet snow coupled with windy conditions could create additional problems, such as towering snow banks and power outages,” said MEMA Executive Director Russell Strickland. “The public also has a part to play in storm preparedness and safety. It is essential that residents be prepared to shelter in their homes, charge all communications devices now, and check on family and friends throughout this snowstorm.”

In addition to staying off the roads and monitoring the weather and power outages, residents should take the following actions:

• Keep devices charged so you will have a way to follow weather forecasts and local emergency information and be able to contact family and friends.

• Be cautious shoveling snow or ice to avoid overexertion. Take frequent breaks and keep hydrated. If snow is accumulating on your rooftop, consider removing snow if it is safe to do so.

• Avoid travel after the snow starts. If you must travel, make sure to have car chargers, kitty litter, or sand for traction, and extra drinks and snacks in case you get stuck in traffic. Let friends or family know of your travel route and expected arrival time.

• Check on friends, neighbors, and relatives, especially the elderly or vulnerable residents who may have trouble staying warm or maneuvering on icy surfaces.
