Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sun Oct 18 2026

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

Off the East Coast of the United States:
A storm-force non-tropical low pressure area is developing along a
frontal boundary tonight off the southeast coast of the United
States. This low is likely to move slowly and erratically over the
next couple of days while it initially remains non-tropical. Later
this week, if the system stays over the Gulf Stream, environmental
conditions could become more conducive for the low to develop some
subtropical characteristics. A subtropical cyclone could form over
the second half of this week as the system begins moving generally
northeastward, offshore of the eastern United States. Regardless of
development, this system will cause high winds, coastal flooding,
and dangerous surf along portions of the U.S. East Coast. Please
consult statements and warnings from local National Weather Service
offices and the Weather Prediction Center for more information,
along with High Seas Forecasts and Storm Warnings issued by the
National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.
