For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on recently
upgraded Tropical Storm Lee, located over the central tropical
1. Eastern Tropical Atlantic (AL96):
A broad low pressure system located several hundred miles southeast
of the Cabo Verde Islands and a nearby tropical wave are producing a
large area of disorganized showers and thunderstorms. Environmental
conditions appear conducive for some gradual development of this
system, and a tropical depression could form later this week or this
weekend while the system moves west-northwestward at 10 to 15 mph
over the eastern tropical Atlantic. This system is expected to move
across the Cabo Verde Islands Wednesday night and Thursday, and
interests there should monitor its progress.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...60 percent.
2. Northeastern Atlantic (ex-Franklin):
Post-Tropical Cyclone Franklin, located a few hundred miles
east-northeast of the Azores, is producing limited shower activity
to the south and east of its center. This system could briefly
acquire some subtropical or tropical characteristics during the next
couple of days while it makes a counterclockwise loop over the
northeastern Atlantic. By late this week, further development is not
expected as the system is forecast to become increasingly elongated
and weaken. For additional information on this system, including
gale warnings, see High Seas Forecasts issued by Meteo France.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
