For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical
Depression Kirk, located about 1000 miles west-southwest of the
Cabo Verde Islands, and on Subtropical Storm Leslie located more
than 1000 miles west of the Azores.
1. A broad area of low pressure located about midway between Bermuda
and the Bahamas continues to produce a limited amount of shower and
thunderstorm activity. Environmental conditions are forecast to
become slightly more conducive for development during the next
day or so while the system moves west-northwestward to
northwestward. By Tuesday night and Wednesday, upper-level winds
are expected to increase, limiting the chances for additional
development, while the system moves northward near the southeastern
United States coast.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
2. A non-tropical low pressure system is expected to form north of
Subtropical Storm Leslie along a cold front over the central
Atlantic by Wednesday. Leslie and the non-tropical low are expected
to merge over the central Atlantic, where conditions appear
conducive for the low to acquire tropical or subtropical
characteristics by the end of the week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
Public Advisories on Leslie are issued under WMO header WTNT33
