1. Showers and thunderstorms associated with a low pressure area
located about 250 miles south of Acapulco, Mexico, continue to show
signs of organization, but recent satellite wind data indicate that
the low does not yet have a closed surface wind circulation.  
Environmental conditions are expected to be conducive for additional
development, and a tropical depression or tropical storm is expected
to form over the next day or so while moving slowly
west-northwestward or northwestward just offshore the southern coast
of Mexico.  Interests along the southern and southwestern coast of
Mexico should monitor the progress of this system during the next
few days, and additional information, including gale warnings, can
be found in High Seas Forecasts issued by the National Weather
Service.

Tropical Depression Seventeen-E Discussion Number   1
NWS National Hurricane Center Miami FL       EP172021
1000 AM CDT Fri Oct 22 2021

Over the past 24 h, the convective organization has steadily
increased in association with the area of low pressure to the
southwest of southern Mexico. Overnight, an ASCAT overpass showed
that the system still lacked a well-defined low-level center.
However, since that time visible satellite imagery reveals that the
disturbance has become much better organized and that a tropical
cyclone has formed. The most recent subjective Dvorak intensity
estimates from both TAFB and SAB were T-2.0/30 kt, and therefore
30 kt is the initial advisory intensity.

The tropical depression is moving 280/9 kt to the south of a
mid-tropospheric ridge. A deep-layer trough is forecast to dig
southeastward toward the western United States this weekend and
early next week, which should create a weakness in the ridge to the
north of the cyclone. This would cause the depression to slow its
forward motion and turn northwest or north-northwest towards this
weakness. There is a fair amount of spread in the model guidance
beyond 24 h, as the various models have different solutions as to
how abrupt of a turn to the right the cyclone will make in response
to the change in the steering flow. The NHC track forecast is near
the HFIP corrected consensus, HCCA, and the TVCE guidance. Based on
the current NHC forecast track, the cyclone would be nearing the
coast of southwestern Mexico in 72 h, and inland by 96 h. However,
due to the larger-than-normal model spread beyond 24 h, that
portion of the forecast track is not particularly of high
confidence.

The cyclone is expected to be within an ideal environment for
strengthening over the next couple of days, with very little
vertical wind shear, a moist airmass, and sea surface temperatures
near 30 degrees C. Therefore, steady intensification is indicated by
all of the model guidance through 60 h. There is some weakening
indicated by the models at 72 h, around the time the system would be
nearing the coast of Mexico,  which could be due to some dry air
entraining into the cyclone's circulation. The NHC intensity
forecast is near the IVCN consensus solution through 72 h but below
HCCA. Beyond landfall, the intensity forecast is near the
Decay-SHIPS prediction. It should be noted that the SHIPS Rapid
Intensification guidance indicates a greater than 60 percent chance
of a 55-kt increase in strength over the next 60 h and 65 kt over
the next 72 h.

Based on the forecast track, intensity, and wind radii, Tropical
Storm or Hurricane Watches may be issued for a portion of the
southwestern Mexico coast as early as tonight.

Tropical Storm Rick Discussion Number   2
NWS National Hurricane Center Miami FL       EP172021
400 PM CDT Fri Oct 22 2021

A curved band of deep convection has wrapped roughly halfway around
and over the estimated center of the cyclone over the past several
hours, and a central dense overcast may be trying to form. Outflow
has been expanding in all directions, indicative of a low-shear
environment. Although there were two recent ASCAT overpasses over
the cyclone, the higher magnitude vectors were likely rain
inflated. Thus, the initial intensity of the system is based on the
latest Dvorak intensity estimates of 35 kt from both TAFB and the
UW-CIMSS ADT, making Rick the seventeenth named storm of the 2021
eastern Pacific basin hurricane season.

Rick has slowed its forward motion and is now moving
west-northwestward at 6 kt. A ridge to the north of the storm is
forecast to weaken tonight as a deep-layer trough digs southeastward
toward the western United States. Rick is expected to turn
northwestward tonight then north-northwestward by Saturday night
towards this weakness. The model guidance is still having a
difficult time agreeing upon how abrupt of a right turn that the
cyclone will make this weekend, with the GFS consistently showing a
northward motion by tonight, and much of the other guidance
indicating the northwest then north-northwest motion over the next
few days. The NHC track forecast was nudged a little to the right of
the previous one due to an overall slight shift to the right in the
guidance, and lies in between the NOAA corrected consensus HCCA,
and FSU Superensemble solutions. It should be noted that the model
spread between the right-outlier GFS and left-outlier ECMWF models
is about 175 n mi at 48 h. Therefore, the track forecast remains of
low confidence.

There is little change to the intensity forecast reasoning. The
storm is expected to be within an ideal environment for
strengthening over the next couple of days, with very little
vertical wind shear, a moist airmass, and sea surface temperatures
near 30 degrees C. Therefore, steady intensification is indicated by
all of the model guidance through 48 h. There is some weakening
indicated by the models just before the time the system would be
nearing the coast of Mexico,  which could be due to some dry air
entraining into the cyclone's circulation. The NHC intensity remains
near the IVCN consensus solution through 72 h and below HCCA. Beyond
landfall, the intensity forecast is near the Decay-SHIPS prediction.
The NHC intensity forecast also calls for a 24-h period of rapid
intensification, which seems reasonable given the environment, the
model agreement, and the SHIPS Rapid Intensification guidance that
now indicates a greater than 60 percent chance of a 45-kt increase
in strength over the next 36 h, and 55 kt over the next 48 h.

Key Messages:

1. Rick is forecast to be a hurricane when it reaches the southwest
coast of Mexico by Sunday night or Monday, and life-threatening
storm surge and hurricane-force winds are possible within the
Hurricane Watch area from Zihuatanejo to Punta San Telmo.  There is
larger-than-normal uncertainty in the track forecast of Rick, and
the arrival time of hazardous conditions within the watch area could
change significantly with future forecasts. Residents in this area
should follow any advice given by local officials and check updates
to the forecast.

2. Rick could bring tropical storm conditions to portions of the
southwestern coast of Mexico as early as Sunday from east of
Zihuatanejo to Tecpan de Galeana, and by Monday morning from west of
Punta San Telmo to Manzanillo, where a Tropical Storm Watch is in
effect.

3. Heavy rains associated with Rick are expected to move into the
Mexican states of Guerrero, Michoacan, and Colima starting Saturday
Night, and could persist through Monday night.  This rainfall will
likely produce flash flooding and mudslides.

Hurricane Rick Discussion Number   6
NWS National Hurricane Center Miami FL       EP172021
400 PM CDT Sat Oct 23 2021

Rick continued to strengthen through the late morning, with a brief
appearance of an eye in visible satellite images.  Over the past few
hours the eye has become less apparent, and the Central Dense
Overcast (CDO) has become a bit elongated.  An Air Force Reserve
Hurricane Hunter Aircraft investigated the hurricane late this
afternoon and was able to provide beneficial data regarding Rick's
structure and intensity.  During the flight, the aircraft measured
peak 700-mb flight-level winds of 80 kt (which reduce to 72 kt at
the surface), and SFMR surface winds of 81 kt a little earlier in
the flight.  A blend of these values suggests the initial advisory
intensity is 75 kt, which agrees well with unanimous 77-kt Dvorak
intensity estimates from TAFB, SAB, and the UW-CIMSS ADT. The
aircraft also confirmed that the core of Rick is compact, with
tropical-storm-force winds extending only about 50 n mi from the
center.  However, earlier scatterometer data sampled winds to near
tropical storm force in the large curved band that wraps around much
of the hurricane's center at a distance of 100 to 150 n mi.

Rick has jogged west-northwest over the past couple hours, but the
12 h motion is about 335/05 kt.  There is no change to the forecast
track reasoning.  Rick is expected to resume a motion between
north-northwest and north, through a weakness in the
mid-tropospheric subtropical ridge, during the next couple of days.
The track model guidance has come into better agreement, and the
only notable change to the NHC forecast track was during the first
12 h to adjust for the recent left-of-track motion.

The environment of sea-surface temperatures near 30 degrees C and
very low shear should support a fast pace of strengthening over the
next day or so.  The only factor that could inhibit the pace of
intensification is the presence of a dry moat between the CDO and
outer band, and some of this dry air could get drawn into the core
of Rick.  However, based on the other favorable factors, the NHC
intensity forecast calls for continued strengthening through Sunday
morning.  As the hurricane nears the coast in 36 h, dry air and
increasing southwesterly vertical wind shear may weaken the cyclone.
The latest NHC intensity forecast still calls for Rick to reach
major hurricane intensity on Sunday, despite the recent pause in
strengthening. This forecast remains on the high end of the
guidance.  

Key Messages:

1. Rick is forecast to be at or near major hurricane strength when
it reaches the coast of southern Mexico by Sunday night or Monday,
and life-threatening storm surge and dangerous hurricane-force
winds are expected within the Hurricane Warning area from Tecpan de
Galeana to Punta San Telmo.  Residents in this area should
follow any advice given by local officials and check updates
to the forecast.

2. Rick is expected to bring tropical storm conditions to
portions of the southern and southwestern coasts of Mexico as early
as Sunday from east of Tecpan de Galeana to Acapulco, and by Monday
morning from west of Punta San Telmo to Manzanillo, where a Tropical
Storm Warning is in effect.

3. Heavy rains associated with Rick are expected to move into the
Mexican states of Guerrero and Michoacan starting later today, and
could persist through Monday night.  This rainfall will likely
produce flash flooding and mudslides.
