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 remains attached
to an occluded frontal boundary a few hundred miles off the North
Carolina coast. This low could develop some organized deep
convection and gradually lose its frontal features over the next
couple of days while it moves slowly north-northeastward over the
Gulf Stream. 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 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...low...30 percent.
* Formation chance through 7 days...medium...40 percent.
