DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Depression Nine 
was located by Air Force reconnaissance aircraft near latitude 23.5 
North, longitude 77.3 West. The depression is moving toward the 
north near 7 mph (11 km/h). A faster motion to the north-northwest 
or north is expected later today and continuing through Monday. On 
the forecast track, the center of the system is expected to move 
across the central and northwestern Bahamas later today and tonight 
and then turn east-northeastward, moving away from the southeastern 
U.S. by the middle part of this week. 
 
Maximum sustained winds remain 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 tropical storm later today and a 
hurricane by late Monday or Tuesday.
 
The estimated minimum central pressure is 1002 mb (29.59 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Depression Nine can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO
header WTNT44 KNHC.
 
WIND: Tropical storm conditions are expected in the central Bahamas
beginning later today and in the northwestern Bahamas late this
afternoon. Tropical storm conditions are possible in the watch area
along the east coast of Florida on Monday.

RAINFALL: Tropical Depression Nine is expected to produce additional 
rainfall of 2 to 6 inches across eastern Cuba and 6 to 12 inches 
across the northwest Bahamas through Tuesday. This rainfall will 
likely produce flash and urban flooding. Mudslides are also possible 
in areas of higher terrain across eastern Cuba.

Storm total rainfall amounts of 2 to 4 inches with local maxima of 
7 inches are expected into Wednesday morning across portions of the 
coastal Carolinas. This rainfall could result in flash, urban, and 
isolated, minor river flooding. Changes in the forecast track could 
result in further adjustments to these rainfall totals.
 
For a complete depiction of forecast rainfall and flash flooding
associated with this system, 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: A storm surge will raise water levels by as much as 1
to 3 feet above ground level along the immediate coast in areas of
onshore winds in the northwestern Bahamas. Near the coast, the
surge will be accompanied by large waves.

Minor coastal flooding is possible in areas of onshore winds over 
the Southeastern U.S. coastline. The water could reach the 
following heights above ground somewhere in the indicated areas if 
the surge occurs over the next several high tide cycles...

Volusia/Brevard County Line, Florida to the South Santee River, 
South Carolina...1 to 2 ft

SURF: Swells generated by this system and Hurricane Humberto will
affect portions of the Bahamas this weekend, and spread to 
much of the east coast of the U.S. early this week. These swells are 
likely to cause life-threatening surf and rip current conditions. 
Please consult products from your local weather office.

1100 AM EDT Sun Sep 28 2025

Structurally, the depression continues to gradually become better 
organized, with an attempt at more bursting convection closer to the 
estimated center. However, recent observations from the ongoing Air 
Force Reserve Reconnaissance aircraft mission have been rather 
underwhelming, which still shows a broad wind field and a peak 
850-mb wind of only 37 kt. Based on this information, the system 
will remain a depression for this advisory with maximum sustained 
wind of 30 kt, which is a little under the satellite-based 
intensity estimates. 

The depression has not really accelerated much yet this morning, and 
it appears to be moving slowly northward at 350/6 kt. A general 
north-northwest to northward motion is expected to continue for the 
next 24-36 hours as southerly steering persists from both an upper 
trough over the southeastern United States and the subtropical ridge 
centered just east of Bermuda. After that period of time, the 
subtropical ridge's steering influence decreases as Hurricane 
Humberto's larger outer circulation creates a large weakness. Given 
the slow motion of the depression so far, it has also remained 
south of a track bifurcation point that was seen yesterday in the 
ensemble guidance. The tropical cyclone now appears more likely to 
turn sharply east-northeastward starting on Tuesday and continuing 
through the remainder of the forecast. The track guidance this cycle 
has made another south and eastward shift, and the NHC track 
forecast has been moved in that direction. In particular, the 
track guidance continues to show much more east-northeastward 
acceleration at the end of the forecast, requiring large speed 
changes in days 4 and 5, and this still might not be fast enough. 
The latest track forecast is very close to the HCCA consensus aid, 
but blends it with a little more of the Google DeepMind ensemble 
mean (GDMI) by the day 5 forecast. 
 
While the depression has not yet developed an inner core, one is 
expected to form in the next 12-24 hours. Some southerly vertical 
wind shear is expected to persist, though it never gets 
prohibitively strong, remaining under 20 kt for the next 48-72 h in 
the GFS-based SHIPS. Therefore, intensification is expected and the 
latest NHC intensity forecast is roughly in line with the intensity 
guidance consensus aids. In 3-4 days, the cyclone is expected to 
find itself in the right entrance region of an intensifying 
upper-level jet, and the enhanced upper-level divergence in that 
time may help support additional intensification even as the shear 
begins to increase towards the end of the forecast. After the system 
passes Bermuda, a strong baroclinic zone is expected to interact 
with the system, resulting in extratropical transition by day 5 as 
it gets tangled up with a frontal boundary. However, as stressed 
previously, this is a low confidence forecast at long range given 
the recent large track changes, especially since the southward shift 
in track keeps the cyclone over warmer sea-surface temperatures.
 
KEY MESSAGES:

1. The depression is expected to strengthen and bring tropical storm 
conditions to portions of the central and northwestern Bahamas 
through Monday. Tropical storm conditions are also possible
along portions of the east coast of central Florida beginning 
Monday.
 
2. Rainfall associated with the system will continue to impact 
eastern Cuba and the Bahamas through Tuesday, which will likely 
produce flash and urban flooding.  Mudslides are possible in the 
higher terrain.  Heavy rainfall across the coastal Carolinas could 
cause flash, urban, and river flooding into Wednesday morning. 
 
3. The risk of significant wind impacts along the southeastern 
United States coast is decreasing, but interests in that area should 
continue to monitor the latest forecast updates. 

4. Swells and high surf from both Humberto and Tropical Depression 
Nine are expected to produce dangerous marine conditions and rip 
currents along the east coast of Florida and the Georgia coast 
through Monday.  These conditions are expected to spread northward 
along much of the east coast of the United States early this week.
