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

The National Hurricane Center is issuing advisories on Hurricane 
Teddy, located over the central tropical Atlantic, and has issued 
the last advisory on Vicky, which has become a remnant low over the 
eastern tropical Atlantic.  The National Hurricane Center has begun 
issuing advisories on newly formed Tropical Depression Twenty-Two, 
located over the southwestern Gulf of Mexico.

1. An elongated area of low pressure located a few hundred miles 
south-southwest of the Cabo Verde Islands is producing disorganized 
shower and thunderstorm activity.  Environmental conditions are 
expected to be conducive for development during the next few days, 
and a tropical depression could form before upper-level winds become 
less favorable by late this weekend.  The system is forecast to move 
west-northwestward at 10 to 15 mph during the next several days.
* Formation chance through 48 hours...medium...40 percent. 
* Formation chance through 5 days...medium...50 percent.

2. Showers and thunderstorms have change little since this morning in 
association with a non-tropical area of low pressure located over 
the far northeastern Atlantic Ocean several hundred miles east of 
the Azores.  This system is forecast to move eastward and then 
northeastward at about 10 mph, and its opportunity for subtropical 
development will soon be decreasing since it is expected to reach 
the coast of Portugal on Friday.  For more information on this 
system, see High Seas Forecasts issued by Meteo France. 
* Formation chance through 48 hours...low...30 percent.
