There are no coastal watches or warnings in effect.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone Gamma
was located near latitude 21.6 North, longitude 88.4 West. The
post-tropical cyclone is moving toward the southwest near 6 mph (9
km/h), and this general motion is expected to continue for the next 
day or so. The post-tropical cyclone is currently centered along 
the northern coast of the Yucatan peninsula and will move inland 
through Monday.
 
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Gradual weakening is anticipated and Gamma is forecast to dissipate 
by Wednesday.
 
The estimated minimum central pressure is 1005 mb (29.68 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Through midweek, the remnants of Gamma are expected to 
produce an additional 2 to 4 inches of rainfall with isolated 
maximum amounts of 8 inches across portions of the Mexican states of 
Yucatan, Campeche, and Tabasco. This rainfall may produce areas of 
flash flooding.
 
 
NEXT ADVISORY

Center on this system. Additional information on this system can be

Gamma was entirely devoid of convection for most of the day. Shortly
before sunset, a few disorganized thunderstorms developed to the
southeast of the cyclone's center, however these appear to be forced
at least in part by a sea breeze boundary and are not exclusively
associated with Gamma. A few other small cells of convection have
developed to the west of Gamma's center during the past hour or so,
but not nearly enough to be considered sufficiently organized to
meet the requirement for a tropical cyclone. Gamma is therefore now
considered to be post-tropical and this will be the last NHC
advisory.
 
The cyclone could still produce some additional disorganized 
convection and periods of heavy rain overnight as it moves inland 
over the Yucatan peninsula, but this is not expected to result in 
significant regeneration. Some of this rain could impact areas that 
are preparing for the much more significant approach of Hurricane 
Delta in a day or so. The cyclone is moving southwestward near 
5 kt, and this should continue for another day or so until it 
dissipates. The winds associated with Gamma's remnants should 
gradually weaken through that time, though the system could still 
produce a few areas of heavy rain over southeastern Mexico.
 
It is worth noting that several model trackers, and consequently
the consensus aids, depict that Gamma will move northward over the
Gulf of Mexico and strengthen significantly in a couple of days.
This is because the trackers lose track of Gamma when it dissipates
and start following nearby Hurricane Delta instead. In reality, no 
models forecast that Gamma will remain a well-defined cyclone for 
more than another day or two.
