As Hurricane Sam and Tropical Depression Victor weaken in the Atlantic Ocean, an area off the southeastern coast of the United States is being monitored for tropical development this week.
A large area of disorganized clouds and showers was over the southeastern Bahamas and adjacent southwestern Atlantic waters on Monday morning. This activity is forecast to slowly drift northwestward in the direction of the Southeast coast over the next several days.
However, the National Hurricane Center said strong upper-level winds will likely hinder this system's chance of developing into a tropical depression or tropical storm, placing the odds at just 10% in the next five days.
Regardless of development, this system will interact with a slow-moving cold front over the Southeast, acting to enhance the heavy rainfall that's already occurring over the region.

Elsewhere in the Atlantic: Sam and Victor
The NHC is also tracking Hurricane Sam and Tropical Depression Victor, both of which are weakening and expected to dissipate soon.
Hurricane Sam
As of Monday morning, Sam was a large Category 2 hurricane with winds around 105 mph and a central pressure of 957 millibars.
The center of the storm was located about 465 miles south-southeast of Cape Race, Newfoundland, and it was moving to the northeast at 30 mph.
The NHC said Sam is expected to take a northeastern motion at a faster forward speed over the next few days before slowing down over the far north Atlantic Ocean. The storm is then expected to become post-tropical by Tuesday.

Tropical Depression Victor
As of Monday morning, Victor was a tropical depression with winds around 30 mph and a central pressure of 1009 millibars.
The storm's center was located in the central tropical Atlantic between the Cabo Verde Islands and the Lesser Antilles.
The NHC said Victor will weaken to a remnant low later Monday as it moves west-northwestward through the open waters of the Atlantic. The storm is forecast to dissipate by Tuesday.
