Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Tue Sep 25 2018

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

The National Hurricane Center has issued the final advisory on
Post-Tropical Cyclone Leslie, located a little more than 1000 miles
west-southwest of the Azores.

1. A broad area of low pressure located about 200 miles south of Cape
Hatteras, North Carolina, continues to produce disorganized showers
and a few thunderstorms.  Satellite and surface data indicate that
the circulation of the low remains elongated and not well defined.
However, this system could still become a tropical depression this
afternoon or tonight while it moves slowly northwestward to
northward.  By Wednesday, additional development appears unlikely
due to strong upper-level winds while the system moves northward and
north-northeastward near the eastern United States coast.  An Air
Force Reserve reconnaissance aircraft is scheduled to investigate
the system later this afternoon.  Regardless of development, this
system is likely to bring scattered showers and thunderstorms across
portions of northeastern South Carolina and eastern North Carolina
this afternoon and tonight.  In addition, dangerous surf conditions
and rip currents are expected along portions of the North Carolina
coast today.  For more information, please see products from your
local National Weather Service office.

* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.....
