Showers and thunderstorms have become more concentrated during the
past several hours near an elongated area of low pressure located
about 100 miles south-southwest of the coast of Guatemala.
Environmental conditions are conducive for development of this
system, and a tropical depression or tropical storm is expected to
form tonight or on Wednesday while the system moves
west-northwestward at about 10 mph, toward the coast of southeastern
Mexico. Regardless of development, heavy rainfall currently
occurring across Costa Rica, Nicaragua, Honduras and El Salvador is
forecast to spread westward over Guatemala tonight, and across
southern Mexico on Wednesday. These rains could cause flooding and
mudslides, especially in mountainous areas. Interests in
southeastern Mexico should monitor the progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

The track of this future storm could be a disaster for those who lives in Chiapas, Oaxaca, Guerrero and Michoacan states on Mexico. This could be the deadliest storm this season on EPAC by far but I hope is not!

Potential Tropical Cyclone Seventeen-E Discussion Number 1
NWS National Hurricane Center Miami FL EP172019
1000 PM CDT Tue Oct 15 2019

Although deep convection associated with the area of low pressure
near the southeastern coast of Mexico has increased since this
afternoon, the overall organization of the system has not increased
enough for it to be considered a tropical cyclone. The system,
however, is predicted to become a tropical storm before it reaches
the southeastern coast of Mexico on Wednesday, and NHC has initiated
advisories on this system as a potential tropical cyclone. The
government of Mexico has elected to issued a tropical storm watch
for a portion of the coast of southeastern Mexico. The initial
intensity of the system is estimated to be 30 kt based on earlier
scatterometer data. The disturbance is located over very warm
waters and within an area of light to moderate northeasterly shear,
which should allow for some strengthening before the system moves
inland. The NHC intensity forecast calls for the disturbance to
become a tropical storm in 12 hours, and it is in good agreement
with the statistical guidance and the global models which show some
slight deepening. The system should quickly weaken and dissipate
over the mountainous terrain of southern Mexico after landfall.

The initial motion estimate is a somewhat uncertain 300/9 kt. A
mid-level ridge over the southeastern Gulf of Mexico is expected to
steer the disturbance west-northwestward during the next day or so,
and this motion should bring the center on the coast within 24
hours. The track guidance is in good agreement and the official
forecast is near the center of the guidance envelope.

The primary threat with this system will be heavy rainfall and the
potential for flash flooding and mudslides in southern Mexico during
the next day or two.

Potential Tropical Cyclone Seventeen-E Discussion Number 3
NWS National Hurricane Center Miami FL EP172019
1000 AM CDT Wed Oct 16 2019

Satellite imagery this morning shows that the disturbance continues
to lack a well-defined center, and there is evidence of multiple
low-level cloud swirls near the mean center. One swirl came
onshore a few hours ago just southwest of Salina Cruz, Mexico,
accompanied by wind gusts to tropical-storm force. Another swirl is
currently near or just offshore of Puerto Angel close to a strong
cluster of convection. The mean position between these swirls used
in this advisory is inland over the Mexican state of Oaxaca. The
initial intensity remains 30 kt based partly on surface observations
and partly from continuity with the previous advisory.

The chances that the system will become a tropical cyclone are
diminishing. However, advisories will continue and the tropical
storm watch will remain in effect until it becomes clear that the
center will not try to re-form offshore. If this does not happen,
the disturbance should dissipate over the mountains of central
Mexico between 12-24 h.

The initial motion is a somewhat uncertain 315/12. A general
northwestward motion should continue until the system dissipates.

The primary threat from this disturbance remains heavy rainfall and
the potential for flash flooding and mudslides in southern Mexico
during the next day or two.


FORECAST POSITIONS AND MAX WINDS

INIT 16/1500Z 16.2N 96.2W 30 KT 35 MPH...POTENTIAL TROP CYCLONE
12H 17/0000Z 17.3N 97.6W 20 KT 25 MPH...INLAND
24H 17/1200Z...DISSIPATED
