Maryland will seek disaster relief from FEMA as the state continues to emerge from its heaviest ever snowfall, Gov. Larry Hogan said Sunday morning.

Hogan thanked people for mostly staying home but urged residents to continue to be patient as state and local road crews continue to try and clear snow.

"Roads are still extremely treacherous," he said.

State Highways Director Gregory C. Johnson said he expects to have interstates and other primary routes cleared by Monday morning, but said secondary and local roads will still be covered by snow for the most part.

Officials gave a sense of the scope of the damage and recovery effort after the state received what Hogan called an entire season's worth of snow in just two days. Every corner of the state was affected by the storm, from Ocean City, which was battered by high waves, to the mountains were deep snows fell. Several roofs collapsed, Hogan said. Officials reported no traffic fatalities.

3,000 pieces of road-clearing equipment and 365,000 tons of salt are being put to use as well as 700 National Guard troops and 212 vehicles.

Hogan's team did not commit to a timeline for having things back to normal, but the governor said it will take "a considerable amount of time."

"Recovery efforts from this historic storm will be extensive, they will take time and patience," he said.
