TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT MON AUG 22 2016

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


A low pressure area associated with a tropical wave is centered
about 300 miles southwest of the southern Cabo Verde Islands. The
associated showers and thunderstorms are well organized. However,
recent microwave satellite data suggests the system has not yet
developed a well-defined circulation. A tropical depression could
form at any time tonight or on Tuesday as the system moves westward
to west-northwestward at 15 to 20 mph over the eastern tropical
Atlantic Ocean.
* Formation chance through 48 hours...high...near 100 percent
* Formation chance through 5 days...high...near 100 percent

TROPICAL DEPRESSION SEVEN DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072016
500 PM AST MON AUG 22 2016

The low pressure area located west-southwest of the Cabo Verde
Islands has developed a well-defined circulation and sufficient
organized convection to be considered a tropical depression.
Microwave imagery suggests that the system is likely still
consolidating, with two or more vorticity centers rotating around
a mean center. The initial intensity is set to 30 kt in agreement
with a satellite intensity estimate from TAFB.

The initial motion is 275/16. The cyclone is on the south side of
a deep-layer ridge over the eastern Atlantic, and as a result it
should move generally west-northwestward for the next 36-48 hours.
Beyond that time, the cyclone is forecast to turn northwestward
toward a weakness in the ridge over the central Atlantic. The
track guidance is in good agreement with this scenario, and the
forecast track lies near the consensus models.

The depression is currently in an environment of light to moderate
easterly vertical shear. This, combined with warm sea surface
temperatures, should allow strengthening. One possible negative
factor, however, is a tongue of African dust/dry air wrapping
around the west side of the circulation. On that basis that the
dry air will not stop development, the intensity forecast calls for
steady strengthening through 72 hours. After that time, arrested
development is likely due to the cyclone encountering moderate to
strong westerly vertical shear.

TROPICAL STORM GASTON ADVISORY NUMBER 2
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072016
1100 PM AST MON AUG 22 2016

...TROPICAL DEPRESSION STRENGTHENS INTO THE SEVENTH TROPICAL
STORM OF THE SEASON...


SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION
-----------------------------------------------
LOCATION...12.6N 30.7W
ABOUT 450 MI...725 KM WSW OF THE SOUTHERNMOST CABO VERDE ISLANDS
MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
PRESENT MOVEMENT...WNW OR 285 DEGREES AT 18 MPH...30 KM/H
MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM AST (0300 UTC), the center of Tropical Storm Gaston was
located near latitude 12.6 North, longitude 30.7 West. Gaston is
moving toward the west-northwest near 18 mph (30 km/h) and this
general motion with a slight decrease in forward speed is
expected during the next couple of days.

Maximum sustained winds have increased to near 40 mph (65 km/h)
with higher gusts. Additional strengthening is expected, and Gaston
is forecast to become a hurricane Tuesday night or Wednesday.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
None.


NEXT ADVISORY

Next complete advisory at 500 AM AST.

TROPICAL STORM GASTON DISCUSSION NUMBER 2
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072016
1100 PM AST MON AUG 22 2016

The convective organization of the tropical cyclone has continued
to increase this evening. A couple of well-defined curved bands of
convection now wrap more than halfway around the center and some
cold cloud tops have recently developed near the center. As a
result, subjective Dvorak T-numbers have increased to T2.5 and
support upgrading the system to a 35-kt tropical storm. Gaston
becomes the seventh tropical storm of the 2016 Atlantic hurricane
season.

Gaston is forecast to move over warm water and remain in a low wind
shear environment during the next couple of days. These favorable
conditions should allow for steady strengthening, and Gaston is
forecast to become a hurricane in about 36 hours, which agrees with
the majority of the intensity guidance. In about 3 days, the
global models suggest that Gaston will be nearing an upper-level
low over the central Atlantic that could cause an increase in
southwesterly shear over the system. This should halt
intensification, and the NHC forecast calls for little change in
strength after 72 hours.

The tropical storm is being steered west-northwestward to the south
of deep-layer ridge over the eastern Atlantic. A west-northwestward
motion with some decrease in forward speed is expected during the
next day or so. After that time, a weakness in the subtropical
ridge over the central Atlantic should cause Gaston to turn
northwestward. The track guidance remains in very good agreement,
and the NHC forecast is close to the various consensus models.
