For the North Atlantic...Caribbean Sea and the Gulf of America:

Off the East Coast of the United States (AL93):
A storm-force non-tropical low pressure area located a few hundred
miles off the North Carolina coast is producing some shower and
thunderstorm activity primarily west of its center. However,
overnight satellite wind data indicated the low was still attached
to an occluded front. Over the next couple of days, the low could
develop some organized deep convection and gradually lose its
frontal features while it moves slowly north-northeastward over the
Gulf Stream, allowing the system to briefly develop subtropical
characteristics. By the end of the week, the system is expected to
accelerate northeastward away from the the eastern United States,
where environmental conditions are expected to become unfavorable
for additional subtropical or tropical development.

Regardless of the status of the system, high winds, coastal
flooding, and dangerous surf are expected along portions of the U.S.
East Coast during the next few days. For more information, please
consult statements and warnings from local National Weather Service
offices and the Weather Prediction Center, along with High Seas
Forecasts and Storm Warnings issued by the National Weather Service.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.
