This will be the biggest threat for Mexico, the massive flooding.

Well convection is warming. New hot tower going off near the center. We'll see if this follows the first 4 systems. Looking promising before falling off. Regardless it'll be a dangerous system because of the rain threat.

Fresh SSMIS pass shows a great low level structure. However it is less defined at the mid levels.

In general, the 00z runs are less bullish.

BULLETIN
Tropical Storm Erick Advisory Number 6
NWS National Hurricane Center Miami FL EP052025
900 PM CST Tue Jun 17 2025

...ERICK FORECAST TO BRING HURRICANE CONDITIONS AND LIFE-THREATENING
FLASH FLOODS TO PORTIONS OF SOUTHERN MEXICO WEDNESDAY NIGHT AND
THURSDAY...


SUMMARY OF 900 PM CST...0300 UTC...INFORMATION
----------------------------------------------
LOCATION...13.1N 94.9W
ABOUT 210 MI...335 KM SSE OF PUERTO ANGEL MEXICO
ABOUT 330 MI...535 KM SE OF PUNTA MALDONADO MEXICO
MAXIMUM SUSTAINED WINDS...60 MPH...95 KM/H
PRESENT MOVEMENT...NW OR 310 DEGREES AT 7 MPH...11 KM/H
MINIMUM CENTRAL PRESSURE...998 MB...29.47 INCHES


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

The government of Mexico has issued a Hurricane Warning from
Puerto Angel to Acapulco. A Hurricane Watch has been issued from
west of Acapulco to Tecpan de Galeana.




Tropical Storm Erick Discussion Number 6
NWS National Hurricane Center Miami FL EP052025
900 PM CST Tue Jun 17 2025

Satellite imagery shows that Erick is becoming increasingly
well-organized. Deep convection has expanded and cooled, with
enhanced infrared imagery indicating cloud tops as cold as -85 C
near the center. A recent SSMIS microwave pass revealed an improved
inner-core structure, including a developing curved band. The latest
Dvorak estimates from TAFB and SAB were T3.0 and T4.0, respectively,
and objective ADT values are approaching T3.5. In addition,
just-received synthetic aperture radar data indicate winds near
50 kt. The initial intensity is increased to 50 kt for this
advisory to represent a blend of these estimates.

Erick is moving northwestward at about 310/6 kt. This slowing in
forward speed is consistent with a weakening of the mid-level ridge
to the north, caused by a mid- to upper-level trough progressing
eastward across the central United States. This general motion is
expected to continue through landfall, with only a gradual increase
in forward speed. The track guidance remains in good agreement and
continues to show the center of Erick approaching the coast of
southern Mexico within the next 24 to 36 hours. Although confidence
in the overall track is relatively high, small deviations could lead
to significant changes in where and when the strongest winds and
coastal impacts occur. The official forecast lies near the consensus
of the HCCA and TVCE aids and is very close to the previous NHC
track.

The environment ahead of Erick remains highly conducive for
additional strengthening, with sea surface temperatures near 29 C,
low vertical wind shear, and abundant mid-level moisture. Several
dynamic regional models bring Erick to major hurricane strength
before landfall, and the Rapid Intensification (RI) guidance
continues to indicate a significant chance for rapid strengthening
in the next 24 to 36 hours. The NHC forecast remains near the upper
end of the guidance envelope but could still be somewhat
conservative, especially if the current trend of improved structure
continues overnight.


KEY MESSAGES:

1. Erick is expected to rapidly intensify before reaching the coast
of southern Mexico on Thursday, and a hurricane warning is in effect
for portions of the coast of Oaxaca and Guerrero coast.

2. Erick will produce heavy rainfall across portions of Central
America and Southwest Mexico through this week. Life-threatening
flooding and mudslides are possible, especially in areas of steep
terrain.

3. A dangerous storm surge is expected to produce coastal flooding
near and to the east of where the center crosses the coast, in
areas of onshore winds.


FORECAST POSITIONS AND MAX WINDS

INIT 18/0300Z 13.1N 94.9W 50 KT 60 MPH
12H 18/1200Z 13.7N 95.7W 65 KT 75 MPH

CB has quickly wrapped around what appears to be an eyewall. Erick is likely to be deepening quicker now.

Btw, the number of June major hurricane landfalls for Mexico is zero.

Not sure why this is still at 50 knots officially to be blunt with the low level structure and ADT estimates as well as SAB estimates supporting near or at hurricane strength.

Quite extreme CDO cooling over the last 3 hours from -55C to -70.5C (so a rate of about -5C/hr). Combined with the IR imagery a very strong indicator that RI has started. The dramatic cooling might even indicate ERI.
