Tropical moisture may put outdoor Memorial Day plans in jeopardy from Washington D.C., to Boston on Monday.
The interaction between an approaching storm from the west and Tropical Depression Two will bring a widespread threat for showers and thunderstorms to the eastern U.S.
"It does appear a system moving across the Northeast on Memorial Day will tap into some tropical moisture and pull it northward," AccuWeather Meteorologist Dan Pydynowski said.

Areas from Washington, D.C, to Boston could get rain and thunderstorms on Memorial Day. Those with outdoor plans should be prepared for wet conditions at any outdoor holiday celebrations.
For areas farther west, any shower and thunderstorm activity will be more spotty in nature, including Harrisburg, Pennsylvania.
Those heading outdoors should have an umbrella and rain jacket handy and seek shelter should a thunderstorm approach the area. Use AccuWeather MinuteCast® to know exactly when a shower or thunderstorm will approach your area.
However, dry conditions are expected in western Pennsylvania and New York. Those celebrating the holiday in Pittsburgh will see dry, sunny conditions.

High temperatures will remain seasonable despite the wet weather and clouds, reaching the 70s and 80s F across the region.
Whether the tropical system will track up the East Coast early next week or stall and weaken across the Carolinas is not yet set in stone.
A track up the East Coast could bring enhanced shower and thunderstorm activity and perhaps a flash flood threat, mainly in low-lying and poor drainage areas.
"Though it is likely not enough to cause flooding issues after Memorial Day, a soaking half an inch to an inch of rain can put a damper on any outdoor plans," Pydynowski said. "The heaviest of the rain and the main flood threat with this tropical system should remain over the eastern Carolinas and perhaps into Virginia."
