Potential Tropical Cyclone Four-E Discussion Number 1
NWS National Hurricane Center Miami FL EP042025
300 PM CST Thu Jun 12 2025
Showers and thunderstorms associated with an area of low pressure
located south of Mexico, that the National Hurricane Center has been
monitoring have increased and are showing signs of organization.
While some mid-level rotation is evident in visible satellite images
near the northeast edge of ongoing convection, the low-level
circulation remains broad and elongated. However, the system is
expected to become a tropical storm tonight or tomorrow, and it is
possible that it will bring tropical storm conditions to land areas
within the next 36 to 48 hours. Therefore, the National Hurricane
Center is initiating Potential Tropical Cyclone advisories for this
disturbance.
The initial motion is more uncertain than normal since the system is
still in the formative stage, but the best estimate is
west-northwestward at about 6 kt. A northwestward to
west-northwestward motion is anticipated during the next few days as
the system moves parallel to the coast of southwestern Mexico, being
steered by a mid-level ridge. Model guidance is in fairly good
agreement with the overall track evolution, although minor track
shifts may cause greater impacts to the coast of Mexico. The NHC
forecast lies near the simple consensus aids. Since the disturbance
currently lacks a well-defined center, users are reminded that the
track forecast uncertainty is typically larger in these situations,
and future track adjustments may be required.
The models suggest a more well-defined center should develop
overnight or tomorrow. Once the system becomes better organized and
develops an inner core, the environmental conditions appear
favorable for strengthening during the next couple of days, with
warm sea surface temperatures and abundant moisture. However, the
system will be dealing with some easterly to northeasterly wind
shear. The NHC forecast shows steady strengthening over the next few
days, although there are some guidance aids such as HCCA and the
hurricane regional models that lie above the current NHC forecast.
Given some uncertainty in how quickly the system consolidates and
the limiting wind shear, the NHC forecast lies near the simple
intensity consensus aids. Beyond day 4, environmental conditions
will become hostile which should lead to weakening, and the system
should struggle to produce convection moving into cooler SSTs and a
more stable air mass. The current NHC forecast has the system
becoming a remnant low at that time, and calls for dissipation by
day 5.
Based on the NHC forecast, Tropical Storm Watches have been issued
for portions of southwestern Mexico.
KEY MESSAGES:
1. The outer bands of Potential Tropical Cyclone Four-E may bring
locally heavy rainfall to the Mexican states of Guerrero, Michoacan,
and Colima through this weekend. Isolated flooding and mudslides,
especially in areas of steep terrain, are possible.
2. The disturbance is forecast to be at tropical storm strength when
it moves near the southwestern coast of Mexico on Saturday. Tropical
storm conditions are possible over portions of that area.

For the eastern and central North Pacific east of 180 longitude:
South of Southern Mexico (EP93):
Showers and thunderstorms are gradually becoming better organized in
association with a broad area of low pressure located a few hundred
miles south of southern Mexico. Environmental conditions appear
conducive for continued development of this system, and a tropical
depression is expected to form in the next day or so while it moves
generally west-northwestward. Interests along the coasts of
southern and southwestern Mexico should closely monitor the
progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.
Offshore of Central America and Southern Mexico:
An area of low pressure is forecast to develop late this weekend or
early next week near the coast of Central America. Environmental
conditions appear conducive for some gradual development of this
system as it moves west-northwestward near the coasts of Central
America and southern Mexico.
* Formation chance through 48 hours...low...near 0 percent.

Post-Tropical Cyclone Cosme Discussion Number 13
NWS National Hurricane Center Miami FL EP032025
800 AM MST Wed Jun 11 2025
Drier mid-level air and stable atmospheric conditions have taken
their toll on Cosme. The system has been devoid of deep convection
for more than 12 hours, with only a swirl of low- to mid-level
clouds evident on satellite imagery. The initial intensity has
been lowered to 30 kt. Given the hostile environment and ongoing
lack of convection, Cosme is not expected to redevelop, and this
will be the final advisory.
The low is now moving toward the east-northeast at about 070/6 kt.
Global model guidance indicates a gradual turn toward the
north-northeast later today, followed by a turn to the north on
Thursday, as the system steadily spins down and dissipates over the
next day or so.
For additional information on the remnant low please see High Seas
