The bam models are very close to the coast of Mexico and some even go inland but GFS and Euro move paralell to the coast.

Was surprised by the classification although is close to the coast. I thought they would do it of Friday as the TWO's mentioned.

Potential Tropical Cyclone Two-E Discussion Number 1
NWS National Hurricane Center Miami FL EP022023
1000 PM CDT Wed Jun 28 2023

The system the NHC has been monitoring off of Mexico is starting to
show signs of organization based on geostationary satellite imagery.
An elongated area of low pressure has formed with convection
gradually building over the past several hours. The current
subjective satellite estimate from TAFB give the disturbance a
T-number of 1.5, suggesting that it is close to becoming a tropical
cyclone, but it has not quite become one yet. The initial intensity
is estimated to 25 kt for this advisory.

The disturbance is moving northwestward at about 10 kt. This
general motion is expected to continue as the system moves along the
southwest periphery of a mid-level trough centered over the
southern United States. At the end of the forecast period, the
system is expected to turn west-northwestward in the low-level flow.
There is increased uncertainty in this track forecast due to the
uncertainty in the location of where the storm will ultimately
form. A more northern position will likely bring the potential
cyclone closer to Mexican coast. The NHC track forecast is closest
to the simple consensus aid.

The potential tropical cyclone is embedded in an environment
conducive for intensification, with low vertical wind shear and high
mid-level moisture. The system is also over warm sea surface
temperatures of more than 30 degrees C. Model guidance is in fairly
good agreement that the disturbance will become a tropical cyclone
in the next day or so and steadily strengthen over the next few
days. Atmospheric and ocean conditions are expected to become more
hostile day 4 and beyond, likely leading to weakening. The official
intensity forecast is closest to the LGEM model.


KEY MESSAGES:

1. A Tropical Storm Warning is in effect along the southwestern
coast of Mexico from Punta Maldonado to Lazaro Cardenas, and
tropical storm conditions should begin within this area by Thursday
afternoon.

2. Locally heavy rainfall of 3 to 5 inches with maximum amounts of
7 inches, is expected across southern Mexico from the state of
Oaxaca westward to the state of Jalisco. These rains could lead to
localized flash flooding.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

Tropical Depression Two-E Discussion Number 2
NWS National Hurricane Center Miami FL EP022023
400 AM CDT Thu Jun 29 2023

Satellite imagery indicates that convection associated with the low
pressure area off the coast of southern Mexico has become better
organized during the past several hours, with convective bands
forming near the center and an outer band in the northern
semicircle near the coast. Based on this, the system is being
designated a tropical depression. The initial intensity is 30 kt in
agreement with a satellite intensity estimate from TAFB.

The initial motion is 310/12 kt. This general motion is expected
to continue for the next 3-4 days as the cyclone moves between a
mid-level ridge over the southwestern United States and Hurricane
Adrian to its west and southwest. After that time, a more westward
motion is expected as the weakening system is steered by Adrian
and a low-level ridge to its northwest. The new NHC forecast track
is similar to the previous track and in good agreement with
the consensus models. However, there is some uncertainty in both
the track and the forward speed, and it is possible the center
could come closer to the coast of Mexico than currently forecast.

Conditions appear favorable for strengthening, as the cyclone
should be in an environment of light- to moderate easterly shear
and high mid-level moisture for the next few days. In addition,
the sea surface temperatures are at or above 30C along much of the
forecast track during that time. The various rapid intensification
indices of the SHIPS model show a significant chance of rapid
development during the next 2-3 days, although the system may be too
close to the coast of Mexico to fully take advantage of the
favorable environment. After 72 h, decreasing sea surface
temperatures along the forecast track should cause a quick
weakening. The official intensity forecast follows the trend of the
guidance and is near the intensity consensus.


KEY MESSAGES:

1. A Tropical Storm Warning is in effect along the southwestern
coast of Mexico from Punta Maldonado to Punta San Telmo, and
tropical storm conditions should begin within this area by Thursday
afternoon.

2. Locally heavy rainfall of 3 to 5 inches with maximum amounts of
7 inches, is expected across southern Mexico from the state of
Oaxaca westward to the state of Jalisco. These rains could lead to
localized flash flooding.

Southerly monsoonal flow + easterly ML flow is not a good combination for maintaining vertical tilt. I would expect a marginal hurricane here.

Tropical Depression Two-E Discussion Number 3
NWS National Hurricane Center Miami FL EP022023
1000 AM CDT Thu Jun 29 2023

The depression is producing a large area of deep convection off the
southern coast of Mexico, however microwave imagery indicates that
the banding features are still in the process of taking shape.
Dvorak intensity estimates are T2.5/35 kt from TAFB and T1.5/25 kt
from SAB, therefore the initial intensity remains 30 kt for this
advisory.

There is still a lot of uncertainty in the location of the
depression's center, and the estimated motion (west-northwestward,
or 300/11 kt) is primarily based on extrapolation from the previous
advisory. A west-northwestward to northwestward motion at a fairly
constant speed is expected during the next 2 days or so while the
system moves between a mid-level ridge over northern Mexico and
Hurricane Adrian to its west. During this period, all of the track
guidance moves the system parallel to and within 100 n mi of the
southwestern coast of Mexico, with the typically reliable ECMWF and
HCCA aids, as well as the new HAFS models, leaning on the right
side of the envelope. The NHC track forecast is closest to those
solutions and is very similar to the previous forecast, although it
has been sped up a bit to account for recent model trends. After
48 hours, the cyclone is expected to gradually bend toward the left
and slow down as Adrian weakens and a stronger ridge develops over
the southwestern United States. However, it is not yet clear how
sharp that bend will be, and the system could approach the southern
part of the Baja California peninsula in 3 to 4 days.

The depression appears poised to strengthen in a low-shear and
moist environment and over very warm sea surface temperatures of
30-31 degrees Celsius. In fact, the intensity guidance has become
much more aggressive on this forecast cycle, including an increase
in the chance for rapid intensification. Most of the guidance
shows the cyclone reaching a peak in intensity in 36-48 hours when
it's very close to the southwestern coast of Mexico, and the new
NHC intensity forecast has been increased rather significantly
to hurricane strength during that period compared to the previous
forecast. Even this forecast could be conservative, as several of
the regional hurricane models, as well as the IVCN and HCCA
consensus aids, are 5-25 kt higher than the official forecast at 36
hours. A combination of shear, a drier atmosphere, and cooler
waters are expected to lead to weakening after 48 hours, and the
system could be a remnant low by day 5.


KEY MESSAGES:

1. The depression is forecast to strengthen quickly and could
become a hurricane by Friday evening, bringing a risk of strong
winds to portions of the southwestern coast of Mexico during the
next couple of days. A Hurricane Watch is now in effect for the
coasts of Michoacan, Colima, and Jalisco, and hurricane conditions
are possible in those areas late Friday through Saturday.

2. Locally heavy rainfall of 3 to 5 inches with maximum amounts of
7 inches, is expected across southern Mexico from the state of
Oaxaca westward to the state of Jalisco. These rains could lead to
localized flash flooding.

It's not a true eye, just a hole in the clouds. Good chance of an upgrade to Beatriz coming soon, though.
