Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Fri Sep 2 2022
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Danielle, located about 925 miles west of the Azores.
East of the Leeward Islands (AL91):
Satellite imagery indicates there has been little change in the
organization of the area of low pressure located several hundred
miles east of the Leeward Islands during the past several hours.
Although environmental conditions remain only marginally conducive,
any additional development of the system over the next few days
would lead to the formation of a tropical depression. The
disturbance is expected to move slowly west-northwestward, toward
the adjacent waters of the northern Leeward Islands. Regardless of
development, locally heavy rains may occur over portions of the
Leeward Islands during the next couple of days, and interests in
that area should monitor the progress of the system. An Air Force
Reserve Hurricane Hunter aircraft is scheduled to investigate the
system this afternoon, if necessary. Additional information on this
system can be found in High Seas Forecasts issued by the National
Weather Service.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...70 percent.
Eastern Tropical Atlantic:
Shower activity associated with a broad area of low pressure
located just northwest of the Cabo Verde Islands has increased
some over the last several hours, but remains poorly organized.
This system is moving into an area of less favorable environmental
conditions, and significant development is not anticipated.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1150 AM EDT Tue Oct 4 2022
Special Tropical Weather Outlook to update discussion of the
tropical wave east of the Windward Islands
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Eastern Tropical Atlantic (AL91):
A broad low pressure system located a few hundred miles
west-southwest of the Cabo Verde Islands continues to produce a
large area of showers and thunderstorms. Environmental conditions
are currently conducive for development, and a tropical depression
is likely to form during the next day or so while moving
northwestward at about 10 mph over the eastern tropical Atlantic.
Upper-level winds are expected to become less conducive for
development by Wednesday and Thursday.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.
East of the Windward Islands (AL92):
Updated: Visible satellite images and recent satellite-derived
wind data suggest that a broad low-level circulation could be
forming in association with the tropical wave located a few hundred
miles east of the southern Windward Islands. Although the wave
is currently being affected by strong upper-level winds, conditions
could become more conducive for a tropical depression to form while
moving westward at about 15 mph, crossing the Windward Islands
tonight and early Wednesday. Conditions appear to become more
conducive for development later this week when the system reaches
the central and western Caribbean Sea. Regardless of development,
locally heavy rainfall and gusty winds are expected over portions of
the Windward Islands tonight and Wednesday. Interests in the
Windward Islands, the ABC Islands, and the northern coast of
Venezuela should monitor the progress of this system. An Air Force
Reserve Hurricane Hunter aircraft is currently enroute to
investigate this system.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...70 percent.
