1. Recent satellite wind data and conventional satellite imagery
indicate that the area of low pressure located near the west-central
coast of Mexico has become better organized and is producing winds
to near tropical storm strength. Some additional development is
possible and this system has the potential to become a short-lived
tropical depression or storm this morning or later today before
it moves inland by Sunday night. Regardless of whether or not this
system becomes a tropical cyclone, heavy rainfall associated with
this disturbance could produce flash flooding and mudslides across
portions of Michoacan, Colima, and Jalisco, especially in areas of
mountainous terrain, during the next couple of days.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

Almost there but may not have time. This fall steering pattern has robbed the season totals of 3 named systems.

[Astromanía]

This is so unexpected, it seems every storm in EPAC for the rest of the season will stay to close to land to develop in something strong but short lived depressions and storms will be common afecting with heavy rainfall and strong wind guts, a cat 1 hurricane a la lorena is not out of cuestion, dangerous ecnomic damages and lives lost will still occur

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

The government of Mexico has issued a Tropical Storm Warning from
Punta San Telmo westward to Playa Perula.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Punta San Telmo to Playa Perula

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 400 AM CDT (0900 UTC), the center of Tropical Depression
Nineteen-E was located near latitude 17.5 North, longitude 104.0
West. The depression is moving toward the north near 7 mph (11 km/h)
and this motion is expected to continue through tonight. On this
track, the center of the depression is forecast to approach the
southwestern coast of Mexico within the warning area today, and
move inland by tonight.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Some slight strengthening is possible, and the depression could
become a tropical storm before it moves inland. Rapid weakening
and dissipation is expected after landfall.

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


HAZARDS AFFECTING LAND
----------------------
RAINFALL: The tropical depression is expected to produce rainfall
accumulations of 5 to 10 inches, with local amounts to 15 inches,
across portions of Nayarit, Jalisco, Colima, and Michoacan in
southwest Mexico through Tuesday night. This rainfall could produce
flash flooding and mudslides within steep terrain.

WIND: Tropical storm conditions are expected within a portion of
the warning area later today.


NEXT ADVISORY

Next intermediate advisory at 700 AM CDT.

Tropical Depression Nineteen-E Discussion Number 1
NWS National Hurricane Center Miami FL EP192019
400 AM CDT Sun Oct 20 2019

Microwave, geostationary satellite, and scatterometer data indicate
that the small area of low pressure located near the southwestern
coast of Mexico quickly became better defined during the evening
hours, and deep convection has persisted and become better
organized overnight. Multiple ASCAT passes revealed winds of at
least 25-30 kt over the southern portion of the circulation, and
based on these data, the system is being classified as a 30-kt
tropical depression.

The depression is moving northward or 355/6 kt. The global models
indicate that the depression will move generally northward around
the western periphery of a mid-level ridge that extends over the
southeastern Gulf of Mexico and eastern Mexico. This motion should
bring the center of the cyclone inland over southwestern Mexico
later today or early tonight. The NHC track forecast follows a
blend of the GFS and ECMWF model fields.

The depression is currently located over warm waters and within an
area of moderate easterly shear. In fact, the center of the
depression is currently located near the eastern edge of the
convective mass. Due to the shear and the very short time the
system is expected to remain over water, only slight strengthening
is predicted. The depression, however, could become a short-lived
tropical storm later today. Once inland, the cyclone should rapidly
weaken and dissipate over the high terrain of southwestern Mexico.

The primary threat with the cyclone will be heavy rainfall
and the potential for flash flooding and mudslides over portions
of southwestern Mexico during the next day or so.

Tropical Depression Priscilla Discussion Number 3
NWS National Hurricane Center Miami FL EP192019
400 PM CDT Sun Oct 20 2019

Priscilla moved inland along the coast of southwestern Mexico around
1930 UTC just to the east of Manzanillo. The rugged terrain in that
area is expected to cause the cyclone to rapidly weaken and
dissipate by 12 hours, if not sooner. Satellite intensity estimates
at 1800 UTC were T2.5/35 kt from TAFB and SAB, and T2.7/37 kt and
38 kt from UW-CIMSS ADT and SATCON, respectively, which supported an
intensity of 35 kt at that time. However, the intensity has been
decreased to 30 kt at the advisory time since Priscilla is now
located inland, with most of the deep convection having been
displaced well to the north of the low-level center.

The initial motion estimate is 360/08 kt. Tropical Depression
Priscilla will continue to move northward and farther inland over
southwestern Mexico, resulting in rapid weakening and dissipation
during the next 12 hours. A 12-hour forecast position was provided
mainly for continuity purposes.

The primary threat with Priscilla and its remnants will be heavy
rainfall, along with the potential for flash flooding and mudslides,
over portions of southwestern Mexico during the next day or two.

Remnants Of Priscilla Discussion Number 4
NWS National Hurricane Center Miami FL EP192019
1000 PM CDT Sun Oct 20 2019

The rugged terrain of Mexico has taken a toll on Priscilla. Surface
observations indicate that the system no longer has a closed
surface circulation, and therefore this is the last advisory
issued by the National Hurricane Center on this system.

Even though the surface circulation has dissipated, there is
still a fair amount of deep convection associated with the
remnant trough over portions of southwestern and west-central
Mexico. Since the surface trough is expected to linger for another
couple of days over southwestern Mexico, there remains a significant
threat of heavy rains and flash flooding over that region.

This was one of the shortest-lived EP storms I've ever seen.

[Astromanía]

I just hope there will be not deaths from this in Mexico

This was one of the shortest-lived EP storms I've ever seen.
