The National Weather Service called for heavy rainfall as a cold front pushes through the region. Local rain totals could reach 2 to 3 inches.

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations," the National Weather Service said in its flood watch. "You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued."

The National Weather Service also declared a coastal flood advisory in:

  • Charles County (Expires 7 p.m. Monday)
  • Southern Baltimore County (Expires 10 a.m. Monday)
  • Baltimore City (Expires 10 a.m. Monday)
  • St. Mary's County (Expires 6 a.m. Tuesday)

  • Dorchester County (Expires 8 p.m. Monday)
  • Wicomico County (Expires 8 p.m. Monday)
  • Somerset County (Expires 8 p.m. Monday)

Advisories are the least urgent weather announcement. Watches are more pressing, and warnings are the most serious.

The Maryland portion of the Chesapeake Bay and the tidal Potomac River are under a hazardous weather outlook for the rest of the day.

The National Weather Service also said an isolated thunderstorm could produce damaging wind gusts or a brief tornado.

Forecasters at AccuWeather said damaging winds will be one of the hazards from any severe storms in the Mid-Atlantic area, though forecasters note that hail and even a few tornadoes also cannot be ruled out.

"Portions of New York, Pennsylvania and Maryland, all reported steady rain on Sunday morning, with widespread rainfall amounts of a quarter of an inch," AccuWeather Meteorologist Nicole LoBiondo said in a forecast. "These areas could have rounds of rain through Monday night before wet weather starts to wane early Tuesday."
