200 PM EDT Sun Sep 23 2018

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

The National Hurricane Center has issued the last advisory
on Tropical Depression Eleven, and is issuing advisories on Tropical
Storm Kirk, located several hundred miles south-southwest of the
Cabo Verde Islands, and on newly formed Subtropical Storm Leslie
located a little more than 1000 miles west-southwest of the Azores.

A broad area of low pressure located between Bermuda and the Bahamas
continues to produce limited shower and thunderstorm activity.
The strong upper-level winds currently affecting the system are
expected to diminish, and this could favor some development during
the next couple of days.  The low is forecast to move westward and
west-northwestward at about 10 mph over the southwestern Atlantic
Ocean and by Tuesday or Wednesday, upper-level winds are forecast
to strengthen again, likely limiting the development.  By then,
the system is expected to be moving by the southeastern coast of
the United States.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

A non-tropical low pressure system is expected to form north of
Subtropical Storm Leslie along a central Atlantic cold front by
Wednesday.  Conditions appear conducive for this system to acquire
subtropical or tropical characteristics by the latter part of this
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
