WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

The government of the Cayman Islands has discontinued all Tropical 
Storm Warnings.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Warning is in effect for...
* Cuban provinces of Pinar del Rio and Artemisa, and the Isle of
Youth

A Storm Surge Watch is in effect for...
* Sabine Pass to Alabama/Florida border
* Vermilion Bay, Lake Borgne, Lake Pontchartrain, Lake Maurepas, and
Mobile Bay

A Hurricane Watch is in effect for...
* Cameron, Louisiana to the Mississippi/Alabama border
* Lake Pontchartrain, Lake Maurepas, and Metropolitan New Orleans

A Tropical Storm Warning is in effect for...
* Cuban provinces of Matanzas, Mayabeque, and Havana

A Tropical Storm Watch is in effect for...
* Mississippi/Alabama border to the Alabama/Florida border.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline, in the indicated locations during the next 48 hours.
For a depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov.

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 elsewhere in central and western Cuba and elsewhere along
the northern U.S. Gulf coast should monitor the progress of this
system.  Hurricane warnings will likely be required for portions of
the northern Gulf coast later today.  Interests in the Dry Tortugas
should also monitor the progress of Ida.

For storm information specific to your area in the United
States, including possible inland watches and warnings, please
monitor products issued by your local National Weather Service
forecast office. For storm information specific to your area
outside of the United States, please monitor products issued by
your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Hurricane Ida was located 
by Cuban radar and Air Force Reserve Hurricane Hunter aircraft near 
latitude 21.6 North, longitude 82.7 West. Ida is moving toward the 
northwest near 15 mph (24 km/h), and this general motion should 
continue over the next few days.  On the forecast track, the
center of Ida will pass over the Isle of Youth during the next 
hour or so, move over western Cuba later today, and move over the 
southeastern and central Gulf of Mexico tonight and Saturday. Ida 
is forecast to make landfall along the U.S. northern Gulf coast 
within the hurricane watch area on Sunday.

Reports from Air Force Reserve reconnaissance aircraft indicate
that the maximum sustained winds are near 75 mph (120 km/h) with 
higher gusts.  Additional strengthening is forecast before the 
center moves over western Cuba later today.  Steady to rapid 
strengthening is expected when Ida moves over the southeastern and 
central Gulf of Mexico over the weekend, and Ida is expected to be 
a major hurricane when it approaches the northern Gulf coast.

Hurricane-force winds extend outward up to 20 miles (30 km) from the 
center.  Tropical-storm-force winds extend outward up to 90 miles 
(150 km) from the center. Sustained winds of 38 mph (61 km/h) and a 
gust to 55 mph (89 km/h) has recently been observed on Cayo Largo, 
Cuba.

The latest minimum central pressure estimated from Air Force
Reserve reconnaissance aircraft data is 987 mb (29.15 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Ida can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC,
and on the web at hurricanes.gov/graphics_at4.shtml?key_messages.

STORM SURGE:  A dangerous storm surge will raise water levels by
as much as 4 to 6 feet above normal tide levels in areas of onshore
winds along the immediate coast of the Isle of Youth and near and to
the east of where the center crosses the coast of western Cuba.
Near the coast, the surge will be accompanied by large and
destructive waves.

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...

Morgan City, LA to Ocean Springs, MS including Lake Borgne...7-11 ft
Rockefeller Wildlife Refuge, LA to Morgan City, LA including
Vermilion Bay...4-7 ft
Ocean Springs, MS to MS/AL border...4-7 ft
MS/AL border to AL/FL border including Mobile Bay...3-5 ft
Lake Pontchartrain...4-6 ft
Lake Maurepas...3-5 ft
Sabine Pass to Rockefeller Wildlife Refuge, LA...2-4 ft

Overtopping of local levees outside of the Hurricane and Storm
Damage Risk Reduction System is possible where local inundation
values may be higher than those shown above.

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.

WIND:  Hurricane conditions are occuring over the Isle of Youth 
and are expected to spread over portions of western Cuba in the 
hurricane warning area by later this afternoon and evening. 
Tropical storm conditions are already beginning to reach portions
of western Cuba and will continue through early Saturday. 

Hurricane conditions are possible in the hurricane watch area along
the northern Gulf coast late Saturday night or Sunday and tropical
storm conditions are possible in the watch area late Saturday night
or Sunday.

RAINFALL:  Ida is expected to produce total rainfall accumulations
of 6 to 10 inches with maximum totals of 15 inches across Jamaica.
Rainfall totals of 8 to 12 inches with isolated maximum amounts of
20 inches are expected across the Cayman Islands and western Cuba,
including the Isle of Youth.  These rainfall amounts may produce
life-threatening flash floods and mudslides.

As Ida approaches the central Gulf Coast Sunday afternoon, total
rainfall accumulations of 8 to 16 inches with isolated maximum
amounts of 20 inches are possible from southeast Louisiana to
coastal Mississippi and Alabama through Monday morning. Ida is
forecast to turn northeast as it moves inland later Monday with
rainfall totals of 4 to 8 inches possible across southern and
central Mississippi. This is likely to result in considerable flash,
urban, small stream, and riverine flooding.

SURF:  Swells generated by this system will affect the Cayman
Islands and Cuba through tonight. Swells will begin reaching
portions of the northern Gulf coast Saturday night or early Sunday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Steady strengthening is forecast during the next few days.  The
depression is expected to become a tropical storm tonight, and
become a hurricane when it is near western Cuba or over the
southeastern Gulf of Mexico.  Additional strengthening is likely
over the Gulf of Mexico, and the system could be near major
hurricane strength when it approaches the northern Gulf coast.

The estimated minimum central pressure from Air Force Reserve 
reconnaissance data is 1006 mb (29.71 inches).

Key messages for Tropical Depression Nine can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO
header WTNT44 KNHC, and on the web at
hurricanes.gov/graphics_at4.shtml?key_messages.

STORM SURGE:  A dangerous storm surge will raise water levels by
as much as 2 to 4 feet above normal tide levels in areas of onshore
winds along the immediate coast of the Isle of Youth and near and to
the east of where the center crosses the coast of western Cuba.
Near the coast, the surge will be accompanied by large and
destructive waves.

WIND:  Tropical storm conditions are expected in the Cayman
Islands tonight, and are expected to reach the Isle of Youth and
portions of western Cuba in the warning area on Friday.

RAINFALL:  The depression is expected to produce total rainfall
accumulations of 6 to 10 inches with maximum totals of 15 inches
across Jamaica.  Rainfall totals of 8 to 12 inches with isolated
maximum amounts of 20 inches are expected across the Cayman Islands
and western Cuba, including the Isle of Youth. These rainfall
amounts may produce life-threatening flash floods and mudslides.

The depression may begin to bring rainfall and potential flooding
impacts to the central Gulf Coast by early Sunday.

SURF:  Swells generated by this system will begin affect Jamaica,
the Cayman Islands and Cuba tonight and Friday. These swells are
likely to cause life-threatening surf and rip current conditions.

Tropical Weather Outlook...Corrected
NWS National Hurricane Center Miami FL
800 AM EDT Thu Aug 26 2021

Corrected 5-day formation probability for the second system

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

Showers and thunderstorms continue to show signs of organization in 
association with a broad area of low pressure located over the 
west-central Caribbean Sea about 150 miles south-southwest of 
Jamaica.  Environmental conditions remain conducive for additional
development, and a tropical depression or tropical storm is 
expected to form later today or tonight while the system moves 
northwestward over the northwestern Caribbean Sea, reaching the 
Cayman Islands tonight and western Cuba and the Yucatan Channel 
Friday and Friday night.  Given the recent developmental trends, 
Tropical Storm Warnings for the Cayman Islands and western Cuba 
could be required later this morning, and an Air Force Reserve 
reconnaissance aircraft is scheduled to investigate the system 
this afternoon.  Regardless of development, locally heavy rainfall 
and flooding are possible over portions of Jamaica and the Cayman 
Islands today and tonight, and will likely spread across Cuba 
and the Yucatan Peninsula on Friday. 

The system is expected to enter into the Gulf of Mexico Friday night 
and continue moving northwestward toward the central or northwestern 
U.S. Gulf coast, potentially bringing dangerous impacts from storm 
surge, wind, and heavy rainfall to portions of the coasts of Texas, 
Louisiana, Mississippi, Alabama, and the Florida Panhandle by Sunday 
and Monday.  However, uncertainty in the system's exact track and 
intensity remains large since the low is just beginning to form.  
Interests in these areas should closely monitor the progress of this 
system and ensure they have their hurricane plans in place.  
Additional information on this system, including gale warnings, can 
be found in High Seas Forecasts issued by the National Weather 
Service.    
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

A trough of low pressure located over the central Atlantic about 
600 miles east of Bermuda continues to produce disorganized showers 
and thunderstorms.  Environmental conditions are forecast to be 
generally conducive for development, and a tropical depression 
is likely to form late this week or this weekend while the system 
moves slowly eastward at 5 to 10 mph. 
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...70 percent.

A tropical wave located over the central tropical Atlantic about 
1000 miles west-southwest of the Cabo Verde Islands is producing 
disorganized showers and thunderstorms.  Environmental conditions 
appear a little more conducive for development during the next few 
days, and a tropical depression could form by the weekend while the 
system moves toward the west-northwest or northwest at 10 to 15 
mph.  Upper-level winds could become less conducive for development 
by early next week.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

4 on All SECPreseason List

Four Florida Gators were named to the preseason Coaches All-SEC Team on Tuesday. Defensive end Zachary Carter and cornerback Kaiir Elam were selected to the First Team, linebacker Ventrell Millermade the Second Team and receiver Jacob Copeland landed on the Third Team.

Elam’s selection comes as no surprise and just a day after he was named a preseason AP All-American. It’s the latest preseason honor for Carter as well after being named on the media’s preseason All-SEC First Team and the Wuerffel Trophy watchlist. Miller, last year’s team leader in tackles (88), and Copeland earned the same spots on the media’s preseason team.
