Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sat Aug 24 2019

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

The National Hurricane Center is issuing advisories on newly-formed
Tropical Depression Five, located about 800 miles east-southeast of
Barbados.

A broad and elongated area of low pressure extending from the
southern Florida peninsula northeastward into the Atlantic is
producing a large area of disorganized showers and thunderstorms,
primarily over the Atlantic north of the Bahamas and east of the
central Florida peninsula. Environmental conditions appear
conducive for gradual development during the next few days, and a
tropical or subtropical depression is likely to form early next week
while the system moves northeastward over the Atlantic offshore of
the southeastern United States coast.

Regardless of development, locally heavy rains are possible over the
northwestern Bahamas and the southern and central Florida peninsula
through the weekend. Interests in the northwestern Bahamas, the
Florida peninsula, and the southeastern coast of the United States
should monitor the progress of this system. An Air Force Reserve
Hurricane Hunter aircraft is scheduled to investigate the system on
Sunday, if necessary.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Surface observations along with satellite imagery and radar data
indicate that a low pressure area is located near the upper
Texas and southwestern Louisiana coasts. The associated shower and
thunderstorm activity shows signs of organization. However, the
system is likely to move inland over eastern Texas and western
Louisiana before tropical cyclone formation can occur. Regardless
of development, this system is expected to bring locally heavy rains
to portions of Louisiana and eastern Texas during the next day or
two.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1120 AM EDT Sat Aug 24 2019

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

Special Tropical Weather Outlook issued to discuss the low pressure
area in the northwestern Gulf of Mexico, the formation of Tropical
Depression Five, and the aircraft for the Florida low.

The National Hurricane Center is issuing advisories on newly-formed
Tropical Depression Five, located about 800 miles east-southeast of
Barbados.

A broad area of low pressure located inland over South Florida
is producing a large area of disorganized showers and thunderstorms
that extends eastward over the northwestern Bahamas and the adjacent
Atlantic waters. Significant development of the low is unlikely
today while it drifts northward over the southern or central Florida
peninsula. However, environmental conditions appear conducive for
gradual development once the low moves off the east-central coast of
Florida over the western Atlantic by Sunday, and a tropical or
subtropical depression is likely to form early next week while the
system moves northeastward offshore of the southeastern United
States coast.

Regardless of development, locally heavy rains are possible over the
northwestern Bahamas and the southern and central Florida peninsula
through the weekend. Interests in the northwestern Bahamas, the
Florida peninsula, and the southeastern coast of the United States
should monitor the progress of this system. The Air Force Reserve
Hurricane Hunter aircraft scheduled to investigate the system this
afternoon has been canceled. Another aircraft is scheduled to
investigate the system on Sunday.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Surface observations and satellite imagery indicate that a low
pressure area has formed just off the upper Texas and southwestern
Louisiana coasts. The associated shower and thunderstorm activity
shows signs of organization. However, the system is likely to move
inland over eastern Texas and western Louisiana before significant
development can occur. Regardless of development, this system is
expected to bring locally heavy rains to portions of Louisiana and
eastern Texas during the next day or two.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

Issued at 1100 AM AST Sat Aug 24 2019 000 WTNT45 KNHC 241457 TCDAT5 Tropical Depression Five Discussion Number 1 NWS National Hurricane Center Miami FL AL052019 1100 AM AST Sat Aug 24 2019 The small low pressure system that the NHC has been tracking the past several days across the tropical Atlantic Ocean has acquired enough deep convection to be classified as a tropical depression, the fifth tropical cyclone of the 2019 hurricane season. Two ASCAT passes between 1200-1300Z this morning indicated that the system had a closed circulation and surface winds of at least 30 kt, and that is the intensity set for this advisory. Upper-level outflow is fair to the northwest and restricted to the southeast due to moderate easterly vertical wind shear. The initial motion estimate is 280/10 kt. The NHC model guidance is in very good agreement that the cyclone will move in a general west-northwestward direction along the southern periphery of a deep-layer ridge for the next 5 days, bring the system through the central or northern Lesser Antilles on Tuesday, and into the northeastern Caribbean Sea on Wednesday and Thursday. The official forecast track is close to the consensus model TVCN, which is a little north of the NOAA HCCA corrected-consensus model. The small cyclone is currently experiencing easterly to southeasterly shear of about 15 kt. The shear is forecast to steadily decrease over the next 24 h and be around 5 kt in the 24-to-72-hour time period. Although the depression is expected to remain embedded in a fairly dry mid-level environment, the small overall circulation, small radius of maximum winds, low shear regime, and warm SSTs of 28.0-28.5 deg C should allow for slow but steady intensification through the 5-day period despite occasional intrusions of dry air. The NHC intensity forecast is a blend of the statistical-dynamical SHIPS and LGEM models, and the more robust HWRF model.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sat Aug 24 2019

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

A broad area of low pressure located inland over South Florida
is producing a large area of disorganized showers and thunderstorms
that extends eastward over the northwestern Bahamas and the adjacent
Atlantic waters. Significant development of the low is unlikely
today while it drifts northward over the southern or central Florida
peninsula. However, environmental conditions appear conducive for
gradual development once the low moves off the east-central coast of
Florida over the western Atlantic by Sunday, and a tropical or
subtropical depression is likely to form early next week while the
system moves northeastward offshore of the southeastern United
States coast.

Regardless of development, locally heavy rains are possible over the
northwestern Bahamas and the southern and central Florida peninsula
through the weekend. Interests in the northwestern Bahamas, the
Florida peninsula, and the southeastern coast of the United States
should monitor the progress of this system. The Air Force Reserve
Hurricane Hunter aircraft scheduled to investigate the system this
afternoon could be postponed if the center of the low remains
inland. Another aircraft is scheduled to investigate the system on
Sunday.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Showers and thunderstorms associated with a small area of low
pressure located about 950 miles east of the Windward Islands are
showing some signs of organization. Environmental conditions appear
conducive for additional development, and a tropical depression is
likely to form during the next day or two while the low moves
westward to west-northwestward at 10 to 15 mph. Conditions appear
less favorable for development when the low reaches the Lesser
Antilles and eastern Caribbean Sea by the middle of next week.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sat Aug 24 2019

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

The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Chantal, located several hundred miles west of
the Azores.

A broad area of low pressure located inland over South Florida
continues to produce a large area of disorganized showers and
thunderstorms that extend eastward over the northwestern Bahamas
and the adjacent Atlantic waters. Significant development of the
low is unlikely today while it drifts northward over the southern
Florida peninsula. Environmental conditions appear conducive to
support gradual development once the low moves off the east-central
coast of Florida over the western Atlantic by Sunday, and a tropical
or subtropical depression is likely to form early next week while
the system moves northeastward offshore of the southeastern United
States coast.

Regardless of development, locally heavy rains are possible over the
northwestern Bahamas and the southern and central Florida peninsula
through the weekend. Interests in the northwestern Bahamas, the
Florida peninsula, and the southeastern coast of the United States
should monitor the progress of this system. The Air Force Reserve
Hurricane Hunter aircraft scheduled to investigate the system later
today could be postponed if the center of the low remains inland
over Florida. Another aircraft is scheduled to investigate the
system on Sunday.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Showers and thunderstorms associated with a small area of low
pressure located about 1050 miles east of the Windward Islands are
showing some signs of organization. Environmental conditions appear
conducive for additional development, and a tropical depression is
likely to form over the weekend or early next week while the low
moves westward to west-northwestward at 10 to 15 mph. Conditions
appear less favorable for development when the low reaches the
Lesser Antilles and eastern Caribbean Sea by the middle of next
week.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.
