DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the disturbance was centered near latitude
18.6 North, longitude 82.8 West. The system is moving toward the
northwest near 6 mph (9 km/h). This general motion is expected
later today and tonight, followed by a faster northward to
north-northeastward motion on Wednesday and Thursday. On the
forecast track, the center of the system is forecast to move
across the northwestern Caribbean Sea through tonight, and
then over the eastern Gulf of Mexico on Wednesday and Thursday.
Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Strengthening is expected during the next few days, and the
system is forecast to become a hurricane on Wednesday and continue
strengthening on Thursday as it moves across the eastern Gulf of
Mexico.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 7 days...high...near 100 percent.
The estimated minimum central pressure is 1002 mb (29.59 inches).
HAZARDS AFFECTING LAND
----------------------
Key Messages for Potential Tropical Cyclone Nine can be found in
the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and
WMO header WTNT44 KNHC and on the web at
hurricanes.gov/text/MIATCDAT4.shtml
RAINFALL: Potential Tropical Cyclone Nine is expected to produce
total rain accumulations of 4 to 8 inches over western Cuba and the
Cayman Islands with isolated totals around 12 inches. Over the
eastern Yucatan Peninsula, 2 to 4 inches of rain is expected with
isolated totals over 6 inches. This rainfall brings a risk of
considerable flooding.
Over the Southeastern U.S., Potential Tropical Cyclone Nine is
expected to produce total rain accumulations of 3 to 6 inches with
isolated totals around 10 inches. This rainfall will likely result
in areas of locally considerable flash and urban flooding, with
minor to isolated moderate river flooding also possible.
For a complete depiction of forecast rainfall associated with
Potential Tropical Cyclone Nine, please see the National Weather
Service Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Bonita Beach to Flamingo...2-4 ft
Dry Tortugas...1-3 ft
Florida Keys...1-3 ft
Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the southern
coast of Pinar del Rio, Cuba, including the Isle of Youth.
Storm surge could raise water levels by as much as 2 to 4 feet above
ground level in areas of onshore winds within the warning area along
the east coast of the Yucatan Peninsula.
WIND: Hurricane conditions are possible within the watch areas in
Cuba and Mexico by early Wednesday. Tropical storm conditions are
expected in the warning areas in Cuba and Mexico beginning later
today. Tropical storm conditions are possible in the watch area
beginning on Wednesday.
SURF: Swells generated by the system will affect the southern coast
of Cuba and the Yucatan Peninsula of Mexico during the next couple
of days. Swells will spread northward toward the west coast of
Florida and the northeastern Gulf Coast on Wednesday and Thursday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Potential Tropical Cyclone Nine Discussion Number 3
NWS National Hurricane Center Miami FL AL092024
1100 PM EDT Mon Sep 23 2024
Satellite imagery indicates that there has been little change in
the organization of the system since earlier today. Most of the
deep convection is over the eastern part of the broad circulation.
Animation of proxy-vis GOES images, and radar observations from
Grand Cayman Weather Service suggest that the disturbance still
does not have a well-defined center of circulation, so the system is
kept as a potential tropical cyclone for the time being. The
advisory intensity is held at 30 kt which is in agreement with a
Dvorak estimate from TAFB. An Air Force reconnaissance aircraft is
scheduled to investigate the area in a few hours to provide a
better description of the system's structure along with an updated
intensity estimate.
The initial motion estimate is a rather uncertain 330/5 kt. During
the next day or so, the disturbance is expected to turn
northwestward along the southern and southwestern side of a
mid-level high pressure area. Then, the high is expected to shift
eastward while a mid-level trough drops into the central United
States. This evolution of the steering pattern should cause the
system to accelerate northward to north-northeastward over the
eastern Gulf of Mexico and toward the northeastern Gulf Coast
through Thursday. There is good agreement in the track guidance, and
the official forecast is close to the corrected dynamical consensus
model, HCCA, prediction. This is also very similar to the previous
NHC forecast.
An upper-level low over the northeastern Yucatan Peninsula has been
imparting some southwesterly vertical wind shear over the
disturbance. This has probably caused a temporary disruption in
development. Dynamical guidance shows this low weakening with time,
resulting in a reduction of shear in an environment that is
otherwise very conducive for intensification. The system is
projected to move over waters of very high ocean heat content,
which should lead to considerable strengthening during the forecast
period. The official intensity forecast is similar to the previous
one and lies between the statistical-dynamical model guidance and
the purely dynamical model predictions. It should be noted that
the 72-hour forecast allows for a little weakening after moving
inland, so the cyclone is still expected to be at major hurricane
strength at landfall.
It should also be noted that the cyclone is expected to grow in
size while it traverses the Gulf. Thus, the storm surge, wind, and
rainfall impacts will extend well away from the center, particularly
to the east of the system. In addition, the fast forward speed
while it crosses the coast will likely result in farther inland
penetration of strong winds over parts of the southeastern United
States after landfall.
KEY MESSAGES:
1. The disturbance is forecast to intensify and be near hurricane
strength when it reaches the far northwestern Caribbean Sea Tuesday
night. Tropical storm conditions are expected over portions of
western Cuba and the northeastern coast of the Yucatan Peninsula
with hurricane conditions possible.
2. The system is expected to intensify into a major hurricane
before it approaches the northeastern Gulf Coast on Thursday. While
it is too soon to pinpoint the exact location and magnitude of
impacts, the potential for life-threatening storm surge and
damaging hurricane-force winds along the coast of the Florida
Panhandle and the Florida west coast is increasing. Hurricane
Watches and additional Storm Surge watches will likely be issued
for a portion of that area Tuesday morning, and residents should
ensure they have their hurricane plan in place.
3. Potential Tropical Cyclone Nine will bring heavy rain to portions
of the western Caribbean, which will cause considerable flooding
and mudslides across western Cuba. Heavy rainfall will likely
result in locally considerable flash and urban flooding across
portions of Florida, with isolated flash and urban flooding
possible across the Southeast, Southern Appalachians, and the
Tennessee Valley Wednesday through Friday. Minor to isolated
moderate river flooding will be possible.

expected somewhere within the warning area, in this case within
the next 24 to 36 hours.
A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.
A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.
Interests along the northeastern Gulf Coast, including the Florida
Panhandle and the Florida west coast, should monitor the progress of
this system. Additional watches or warnings will likely be
required on Tuesday.
For storm information specific to your area in the United
States, including possible inland watches and warnings, please

latitude 18.4 North, longitude 82.4 West. The system is moving
toward the north-northwest near 6 mph (9 km/h). A northwestward
motion is expected on Tuesday and Tuesday night, followed by a
faster northward to north-northeastward motion on Wednesday and
Thursday. On the forecast track, the center of the system is
forecast to move across the northwestern Caribbean Sea through
Tuesday night, and then over the eastern Gulf of Mexico on Wednesday
and Thursday.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Strengthening is expected during the next few days, and the system
is forecast to become a hurricane on Wednesday and continue
strengthening on Thursday as it moves across the eastern Gulf of
Mexico.
* Formation chance through 48 hours...high ...90 percent.
* Formation chance through 7 days...high...90 percent.
The estimated minimum central pressure is 1002 mb (29.59 inches).
HAZARDS AFFECTING LAND
----------------------
Key Messages for Potential Tropical Cyclone Nine can be found in
the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and
WMO header WTNT44 KNHC and on the web at
hurricanes.gov/text/MIATCDAT4.shtml
RAINFALL: Potential Tropical Cyclone Nine is expected to produce
total rain accumulations of 4 to 8 inches over western Cuba and the
Cayman Islands with isolated totals around 12 inches. Over the
eastern Yucatan Peninsula, 2 to 4 inches of rain is expected with
isolated totals over 6 inches. This rainfall brings a risk of
considerable flooding.
Over the Southeastern U.S., Potential Tropical Cyclone Nine is
expected to produce total rain accumulations of 3 to 6 inches with
isolated totals around 10 inches. This rainfall will likely result
in areas of locally considerable flash and urban flooding, with
minor to isolated moderate river flooding also possible.
For a complete depiction of forecast rainfall associated with
Potential Tropical Cyclone Nine, please see the National Weather
Service Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Bonita Beach to Flamingo...2-4 ft
Dry Tortugas...1-3 ft
Florida Keys...1-3 ft
Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the southern
coast of Pinar del Rio, Cuba, including the Isle of Youth.
Storm surge could raise water levels by as much as 2 to 4 feet above
ground level in areas of onshore winds within the warning area along
the east coast of the Yucatan Peninsula.
WIND: Hurricane conditions are possible within the watch areas in
Cuba and Mexico by early Wednesday. Tropical storm conditions are
expected in the warning areas in Cuba and Mexico beginning on
Tuesday. Tropical storm conditions are possible in the watch area
beginning on Wednesday.
SURF: Swells generated by the system will affect the southern coast
of Cuba and the Yucatan Peninsula of Mexico during the next couple
of days. Swells will spread northward toward the west coast of
Florida and the northeastern Gulf Coast on Wednesday and Thursday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Potential Tropical Cyclone Nine Discussion Number 2
NWS National Hurricane Center Miami FL AL092024
500 PM EDT Mon Sep 23 2024
Showers and thunderstorms associated with the disturbance are
gradually becoming better organized this afternoon, although the
convection is mostly confined to the eastern portion of the
circulation. Scatterometer winds and aircraft data indicate the
disturbance still lacks a well-defined center, with very light winds
noted on the west side of the broad, elongated circulation. The
scatterometer data did show stronger winds near the convection on
the east side, and based on this along with the aircraft winds, the
initial intensity is raised to 30 kt for this advisory.
The estimated initial motion is north-northwestward (345/6 kt), but
the disturbance should turn more northwestward during the next day
or so. The NHC forecast shows the center of the system passing
between the Yucatan Peninsula and the western tip of Cuba late
Tuesday night, then moving into the southern Gulf of Mexico on
Wednesday. From there, the flow between a deep-layer trough over the
central United States and a ridge over the western Atlantic should
cause the system to accelerate northward to north-northeastward
across the eastern Gulf of Mexico and toward the northeastern Gulf
Coast and Florida Panhandle through Thursday. The track guidance is
very tightly clustered on this solution, and the official NHC
forecast is essentially an update of the previous one.
The moderate southwesterly shear over the disturbance is expected to
diminish over the next day or two, which should allow the system to
become better organized and consolidate over deep, warm waters in a
very moist environment. Once the system develops an inner core,
these conditions should allow it to significantly strengthen. The
NHC forecast still calls for the system to become a hurricane on
Wednesday, with continued intensification thereafter while it moves
over the eastern Gulf of Mexico. Once again, the statistical RI
guidance (SHIPS and DTOPS) show a 65-kt increase in 72 h is very
likely, and the updated NHC forecast now explicitly shows the system
reaching major hurricane intensity on Thursday. This intensity
forecast still lies below the consensus aids, with the regional
hurricane models and the GFS showing even more deepening.
Note that the system is expected to grow in size while it traverses
the Gulf. Thus, the storm surge, wind, and rainfall impacts will
extend well away from the center, particularly to the east of the
system. In addition, the fast forward speed as it approaches the
coast will likely result in farther inland penetration of gusty
winds over parts of the southeastern United States after landfall.
KEY MESSAGES:
1. The disturbance is forecast to intensify and be near hurricane
strength when it reaches the far northwestern Caribbean Sea Tuesday
night. Tropical storm conditions are expected over portions of
western Cuba and the northeastern coast of the Yucatan Peninsula
with hurricane conditions possible.
2. The system is expected to intensify into a major hurricane
before it approaches the northeastern Gulf Coast on Thursday. While
it is too soon to pinpoint the exact location and magnitude of
impacts, the potential for life-threatening storm surge and
damaging hurricane-force winds along the coast of the Florida
Panhandle and the Florida west coast is increasing. Storm Surge
and Hurricane Watches will likely be issued for a portion of that
area tonight or Tuesday morning, and residents should ensure they
have their hurricane plan in place.
3. Potential Tropical Cyclone Nine will bring heavy rain to portions
of the western Caribbean which may lead to flooding and possible
mudslides in western Cuba.
