DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Hurricane Isaias was
located near latitude 23.7 North, longitude 90.2 West. Isaias is
moving toward the east-northeast near 10 mph (17 km/h). A turn
toward the northeast is expected later today followed by a turn
northward on Friday. On the forecast track, Isaias is expected to
pass to the north of the Yucatan Peninsula later today and make
landfall along the U.S. northern Gulf Coast within the warning area
late Friday or early Saturday.
Maximum sustained winds have increased to near 85 mph (140 km/h)
with higher gusts. Additional strengthening is expected through
early Friday, and Isaias should remain a dangerous hurricane as it
approaches the northern Gulf Coast Friday night.
Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 90 miles
(150 km).
The estimated minimum central pressure is 975 mb (28.80 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Isaias can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.
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...
Ocean Springs, MS to Indian Pass, FL...5-7 ft
Mobile Bay...5-7 ft
Indian Pass, FL to Steinhatchee River, FL...4-6 ft
Mouth of the Mississippi River, LA to Ocean Springs, MS...3-5 ft
Steinhatchee River, FL to Suwannee River, FL...3-5 ft
Suwannee River, FL to Yankeetown, FL...2-4 ft
The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.
For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.
WIND: Hurricane conditions are expected within the Hurricane Warning
area Friday night into early Saturday, with tropical storm
conditions beginning on Friday. Tropical storm conditions are
expected in the warning areas on Friday and Friday night.
Gusty winds are possible in portions of the Yucatan Peninsula today.
RAINFALL: Isaias is expected to produce rainfall amounts of 1 to 3
inches through Thursday across coastal portions of the eastern Bay
of Campeche with isolated higher amounts possible in the states of
Campeche and western Yucatan.
From Friday through the weekend, Isaias is expected to produce
rainfall amounts of 3 to 7 inches across the central U.S. Gulf Coast
extending from far southeastern Louisiana to the Florida Big Bend
region. Localized totals up to 15 inches are possible, particularly
within banding across the Florida Panhandle and Big Bend. Rainfall
amounts of 1 to 3 inches, with localized amounts up to 5 inches, are
possible across much of the Southeast as far north as the Tennessee
Valley and the Carolinas. Flash and urban flooding is possible
across the region, with considerable impacts possible across much of
southern Alabama and the Florida Panhandle into southwestern
Georgia. River flooding is also expected, some of which could be
significant.
For a complete depiction of forecast rainfall associated with
Tropical Storm Isaias, 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.
TORNADOES: Isolated tornadoes will be possible Friday night in
coastal areas of Alabama and the Florida Panhandle and far
southwestern Georgia. The tornado threat will continue Saturday for
eastern Alabama, Georgia and northern Florida.
SURF: Swells will affect the western and northern portions of the
Yucatan Peninsula beginning later today and spread northward toward
the Gulf Coast on Friday. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Hurricane Isaias Discussion Number 8
NWS National Hurricane Center Miami FL AL092026
1000 AM CDT Thu Oct 08 2026
Isaias is strengthening in an environment of moderate vertical wind
shear. Observations from an Air Force Hurricane Hunter aircraft
indicate that the central pressure continues to fall and the
maximum winds are now near 75 kt. The center of the hurricane is
near the southwestern side of a Central Dense Overcast feature, and
some convective banding features are evident over the eastern
portion of the circulation. Additional aircraft reconnaissance
missions are scheduled for today, tonight, and Friday, so we will
have close monitoring of the intensity of the system up until
landfall.
Center fixes from the Hurricane Hunters indicate that Isais
continues on a generally east-northward track with an initial
motion of about 060/9 kt. During the next 36 hours, the hurricane
should gradually turn toward the northeast and north as it moves
between a ridge extending from the Bahamas across the Florida
Peninsula and a zonally-oriented mid-level trough near the
northwestern Gulf coast. On the forecast track, the center of the
hurricane is forecast to move across the east-central to
northeastern Gulf coast in 36-42 hours. Thereafter, the weakening
cyclone should move over the southeastern United States bringing
strong winds well inland. The track guidance has not changed much
for this advisory cycle and the official forecast is similar to that
of the previous advisory.
The intensity forecast up to landfall is somewhat challenging.
On the one hand, the hurricane should move over waters of high
oceanic heat content and within a fairly moist air mass through
tomorrow. On the other hand, the SHIPS model input parameters show
a significant increase in vertical wind shear, particularly when
Isais nears the coast. Regarding, the shorter-term intensity
forecast, a recent WSFM microwave satellite image at 37 GHz
frequency shows a closed ring around the eye. This is typically a
harbinger of rapid intensification. The 12-hour forecast does show
a relatively large increase in strength, but in view of the
expected stronger shear in 24-36 hours, some decrease in intensity
is indicated as Isaias approaches the coast. Regardless, Isaias is
expected to remain a dangerous hurricane through landfall, and
gusty winds are expected well inland after landfall given the
anticipated expansion of the wind field and accelerating forward
speed of the storm.
Key Messages:
1. A life-threatening storm surge is expected from the Mouth of the
Mississippi River to Suwannee, Florida. Residents in the warning
area should follow advice given by local officials and evacuate
immediately if told to do so.
2. Damaging hurricane force-winds are expected over portions of the
Florida Panhandle, southern Alabama, and southern Mississippi where
a Hurricane Warning is in effect. Residents in these areas should
prepare for the possibility of long-duration power outages.
3. Damaging wind gusts are possible over much of central and
northern Alabama and portions of western and northern Georgia,
especially in areas of higher terrain. Additional Tropical Storm
and High Wind Watches and Warnings will likely be required for
portions of that area later today. Residents should secure loose
outdoor items, avoid driving high-profile vehicles, and prepare for
power outages.
4. Isaias will bring areas of heavy rainfall to the central U.S.
Gulf coast and much of the Southeast Friday into the weekend.
Considerable flash and urban flooding, along with significant river
flooding, will be possible.
5. Isaias could bring gusty winds and areas of heavy rain to the
western portion of the Yucatan Peninsula today.
