Tropical Storm Gilma Forecast Discussion Number 2

11 months 2 weeks ago
Issued at 200 PM MST Sun Aug 18 2024 000 WTPZ42 KNHC 182042 TCDEP2 Tropical Storm Gilma Discussion Number 2 NWS National Hurricane Center Miami FL EP072024 200 PM MST Sun Aug 18 2024 Despite continued moderate easterly vertical wind shear, deep convection has been expanding and has now built over the center of the system. Accordingly, the Dvorak estimates have nudged upward and are now between 30 and 35 kt. Based on those classifications and the improving convective pattern, the initial intensity is increased to 35 kt, making the system Tropical Storm Gilma. Moderate easterly vertical wind shear of about 20 kt is expected to continue during the next day or so, which should limit the amount of strengthening in the short term. The shear is expected to lessen some after that, and the somewhat more favorable upper-level wind environment combined with warm waters and a relatively moist atmosphere should allow for gradual strengthening throughout much of the week. The NHC intensity forecast is higher than the previous one and roughly between the HCCA and IVCN guidance. Gilma is moving west-northwestward, or 285 degrees, at 12 kt. A high pressure ridge situated to the system’s north should cause the storm to move westward to west-northwestward at about the same speed during the next couple of days. Later in the week, the models show the ridge weakening as a trough amplifies off the west coast of the U.S., which should cause the system to slow down and turn a bit to the right. There is quite a bit of along-track spread in the models, with the GFS being the slowest model and HWRF/HAFS the fastest. The NHC track forecast is similar to the previous one through 60 h and then is a little to the north of the prior track after that. This forecast is close to the various consensus models.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sun Aug 18 2024

For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Seven-E, located well south of the southern tip
of the Baja California peninsula.

Well Southeast of the Hawaiian Islands:
Another area of low pressure located well southeast of the Hawaiian
Islands is producing some disorganized showers and thunderstorms on
its western side. This disturbance is forecast to interact with the
disturbance located to its east. If this system becomes the dominant
disturbance, some gradual development is possible, and a tropical
depression could form by the middle part of the week while it
initially moves slowly over the western portion of the East Pacific.
A faster west-northwestward motion into the Central Pacific basin is
likely by the latter portion of the week. Information on this
system's development can also be found in the Tropical Weather
Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...50 percent.

Western Portion of the East Pacific:
Disorganized showers and thunderstorms continue in association with
a broad trough of low pressure located well west-southwest of the
southern tip of the Baja California peninsula. This system is
forecast to interact with another disturbance to its west-southwest
over the next few days, which could limit additional development if
this system does not become the dominant disturbance. Regardless, a
tropical depression could still form during the middle part of the
week while the system moves generally west-northwestward before it
possibly merges with the disturbance currently located further west.
Information on this system's development can also be found in the
Tropical Weather Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

Eastern and Central Portion of the East Pacific:
Yet another area of low pressure could form well to the south of the
southwestern coast of Mexico around the middle of the week.
Environmental conditions appear generally conducive for some slow
development of this system thereafter as it moves slowly
west-northwestward into the central portion of the East Pacific
basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

The Tropical Weather Outlook for the Central Pacific basin can be
found under AWIPS header HFOTWOCP and WMO header ACPN50 PHFO and on

Tropical Depression Seven-E Forecast Discussion Number 1

11 months 2 weeks ago
Issued at 800 AM MST Sun Aug 18 2024 000 WTPZ42 KNHC 181433 TCDEP2 Tropical Depression Seven-E Discussion Number 1 NWS National Hurricane Center Miami FL EP072024 800 AM MST Sun Aug 18 2024 The low pressure system well south of the southern tip of the Baja California peninsula has now developed a well-defined center and sufficiently organized deep convection. These criteria indicate a new tropical depression has formed, the seventh one of the 2024 East Pacific hurricane season. The initial intensity is set at 30 kt, based on a Dvorak 2.0 classification from TAFB. Moderate easterly vertical wind shear of 15-20 kt is confining most of the thunderstorm activity to the western half of the circulation, and since the shear is expected to persist through tonight, only a little strengthening seems likely in the short-term. The shear should lessen beginning early Monday, and the more favorable upper-level wind environment combined with warm waters and a relatively moist atmosphere should allow for gradual strengthening throughout much of the week. The NHC intensity forecast is closest to the HCCA guidance. The initial motion is uncertain since the system has just formed, but the best estimate is 290/11 kt. A high pressure ridge situated to the system’s north should cause the cyclone to move westward to west-northwestward at about the same speed during the next few days. Later in the week, the models show the ridge weakening as a trough amplifies off the west coast of the U.S., which could cause the system to slow down. The models are in fair agreement with the exception of the GFS, which shows a much slower motion likely due to the interaction with a disturbance to its west. At this point, that model seems unrealistic so it is being discounted for now. The NHC track forecast is in best agreement with the ECMWF and HCCA aids.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Sun Aug 18 2024

For the eastern North Pacific...east of 140 degrees west longitude:

Well Offshore of Southwestern Mexico (EP99):
An area of low pressure located several hundred miles off the
southwestern coast of Mexico is producing showers and thunderstorms
that continue to show signs of organization. Recently-received
microwave satellite imagery also suggests the system is developing a
well-defined center, and if these trends continue, a tropical
depression is likely to form as soon as later today. The system is
forecast to move west-northwestward at about 10 to 15 mph across the
central portion of the eastern Pacific during the next several
days.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

Western Portion of the East Pacific:
Disorganized showers and thunderstorms are associated with a broad
trough of low pressure located well west-southwest of the southern
tip of the Baja California peninsula. This system is forecast to
interact with another disturbance to its west-southwest over the
next several days, which could limit additional development if this
system does not become the dominant disturbance. Regardless, a
tropical depression could still form during the middle part of the
week while the system moves westward to west-northwestward over the
western portion of the East Pacific basin before it possibly merges
with the disturbance currently located further west. Information on
this system's development can also be found in the Tropical Weather
Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...50 percent.

Well Southeast of the Hawaiian Islands:
Another area of low pressure located well southeast of the Hawaiian
Islands is currently associated with some disorganized showers and
thunderstorms on its western side. This disturbance is forecast to
interact with the disturbance located to its east. If this system
becomes the dominant disturbance, some gradual development is
possible and a tropical depression could form by the middle part of
this week while it initially moves slowly over the western portion
of the East Pacific. A faster west-northwestward motion into the
Central Pacific basin is likely by the latter portion of the week.
Information on this system's development can also be found in the
Tropical Weather Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...40 percent.

Eastern and Central Portion of the East Pacific:
Yet another area of low pressure could form well to the south of the
southwestern coast of Mexico over the next few days. Environmental
conditions appear generally conducive for some slow development of
this system thereafter as it moves slowly west-northwestward
throughout the week into the Central portion of the East Pacific
basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

1100 PM PDT Sat Aug 17 2024

For the eastern North Pacific...east of 140 degrees west longitude:

Well Offshore of Southwestern Mexico (EP99):
A broad area of low pressure located several hundred miles off the
southwestern coast of Mexico is producing showers and thunderstorms
that are becoming better organized. Upper-level winds are forecast
to become more conducive for additional development, and a tropical
depression is likely to form in the next couple of days while the
system moves west-northwestward at about 10 to 15 mph across the
central portion of the eastern Pacific.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...90 percent.

Western Portion of the East Pacific:
Disorganized showers and thunderstorms are associated with a broad
trough of low pressure located well west-southwest of the southern
tip of the Baja California peninsula. While this system may
interact with another disturbance to its west-southwest over the
next several days, some gradual development is forecast assuming it
becomes the dominant disturbance. A tropical depression is likely
to form during the middle part of next week while the system moves
westward to west-northwestward over the western portion of the basin
and into the Central Pacific basin by the end of the week.
Information on this system's development can also be found in the
Tropical Weather Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...high...70 percent.

Well Southeast of the Hawaiian Islands:
A small area of low pressure located well southeast of the Hawaiian
Islands is associated with some disorganized showers and
thunderstorms. Some development of this system is possible early
next week while it moves slowly over the western portion of the East
Pacific or in the Central Pacific basin. By the middle of next week,
this disturbance could merge with an area of low pressure developing
to its east. Information on this system's development can also be
found in the Tropical Weather Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
