Tropical Storm Pilar Discussion Number 6
NWS National Hurricane Center Miami FL EP192023
1000 PM CDT Sun Oct 29 2023
A small but concentrated convective burst has been persisting near
the estimated center of the tropical cyclone tonight. After the
prior advisory, we received a fortuitous GPM microwave pass valid
at 2252 UTC that suggested the low-level circulation may have
tightened up some but was located just south of the deepest
convection. Subjective Dvorak intensity estimates were up to T2.5/35
kt form TAFB and T2.0/30 kt from SAB. The objective estimates from
ADT, SATCON, and D-PRINT/MINT are all between 34-36 kt, and thus the
latest advisory is set at 35 kt this advisory, upgrading TD19-E to
Tropical Storm Pilar.
A more pronounced east-northeastward motion appears to be starting,
estimated at 060/4 kt. A continued motion to the east-northwest is
anticipated over the next 24-48 hours as Pilar's primary steering
influences are an equatorial ridge south of the storm providing
deep-layer westerlies in addition to a mid- to upper-level cutoff
low over the northwestern Caribbean that is interrupting the more
typical ridging that would be present to the north over Mexico. The
guidance is in general agreement on this scenario, but how far east
the tropical storm gets in the next 48 h remains uncertain, with the
latest HWRF and HAFS-B runs far enough east to affect the Gulf of
Fonseca with tropical storm conditions. For this reason, the
tropical storm watch has been extended eastward to portions of the
Pacific coast of Honduras and Nicaragua this advisory. On Tuesday,
Pilar is expected to stall and move very slowly as low to mid-level
ridging attempts to build back in to the north of the tropical
cyclone and a strong cold front induces a significant gap wind flow
event in the Gulf of Tehuantepec. By the middle of this week, the
enhanced low-level flow associated with the ridge and gap winds are
forecast to push Pilar away from Central America to the
west-southwest as a weakening tropical storm. As discussed
previously, the confidence of when or how sharp this turn away from
Central America will be is low given the inconsistent model guidance
over the past day. The NHC track this cycle is just a bit closer to
the coast and a touch east of the prior track, but is roughly in
between the TVCE and HCCA consensus aids.
A small core may be starting to take shape given the earlier
microwave imagery, and the persistent area of convection that Pilar
has been maintaining over the last 3-6 hours near the estimated
center. Most of the guidance maintains this small core structure
with intensification while the storm remains embedded in moderate
(15-20 kt) easterly vertical wind shear but is over warm 28-29 C
sea-surface temperatures in a moist mid-level air environment. The
latest NHC intensity forecast still takes Pilar to near hurricane
intensity in 36 h, on the higher end of the intensity guidance but
not far off the hurricane-regional guidance solutions. Afterwards,
it seems likely a combination of the dry mid-latitude gap-wind flow
in addition to possible cool upwelling of the shallow warm waters
due to slow motion near the coast of Central America could begin a
weakening trend. If the latest HWRF and HAFS-B runs end up being
correct, land interaction could also result in weakening. The
intensity forecast beyond 48 h is a little lower than the prior
advisory, as it is looking more likely that a combination of
moderate shear and additional dry stable air could prevent the storm
from re-intensifying even after it begins to move back over warmer
ocean waters away from its own cold wake.
Key Messages:
1. Heavy rains from the tropical depression will produce flash and
urban flooding, along with mudslides in areas of higher terrain
along the Pacific coast of Central America, including El Salvador,
through Wednesday.
2. Tropical storm conditions are possible by early Tuesday into
Wednesday along portions of the Pacific coast of El Salvador,
Honduras, and Nicaragua where a Tropical Storm Watch is now in
effect. Interests elsewhere along the Pacific coast of Guatemala,
and Nicaragua should monitor the progress of this system as
additional watches or warnings could be needed tomorrow.
3. Swells generated by the depression will begin to affect portions
of the Pacific coast of Central America, including El Salvador,
beginning on Monday. These swells are likely to cause
life-threatening surf and rip current conditions.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sun Oct 29 2023
For the eastern North Pacific...east of 140 degrees west longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Nineteen-E, located a few hundred miles southwest of the
coast of El Salvador.
Southwestern East Pacific (EP93):
An area of low pressure located more than 1000 miles south-southwest
of the southern tip of the Baja California peninsula is producing
disorganized showers and thunderstorms. Environmental conditions
are marginally conducive for slow development of this system
during the next couple of days while the low drifts generally
northeastward. By the middle of the week, upper-level winds are
forecast to become less conducive for additional development.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...low...30 percent.

Tropical Depression Nineteen-E Discussion Number 2
NWS National Hurricane Center Miami FL EP192023
1000 PM CDT Sat Oct 28 2023
The organization of the depression has not improved this evening.
The shower and thunderstorm activity has diminished and is mostly
confined to the northern and western portions of the circulation.
Recent satellite-derived wind data and microwave images suggest the
depression has not moved much since earlier today. Based on the
earlier scatterometer data, current structure, and a T2.0 subjective
Dvorak estimate from TAFB, the initial intensity is held at 30 kt.
The depression is currently within weak steering currents, and
little net motion is expected through Sunday while the system
meanders offshore of Central America. By early next week, the flow
associated with a mid- to upper-level trough over the northwestern
Caribbean Sea should steer the system generally northeastward
towards Central America. While the track models agree in principle
on this scenario, it remains unclear how close the cyclone will get
to the coast in 60-72 h and whether or not it will move inland.
Given this uncertainty, interests in Guatemala and El Salvador
should closely monitor the latest forecast updates, as only small
track changes could result in greater land impacts. By the middle of
next week, the flow behind a cold frontal passage to the north
should push the cyclone southwestward and away from land. The
updated NHC track forecast lies between the previous prediction and
the latest multi-model consensus aids.
Given the current structure of the depression, only modest
strengthening is forecast in the near term. Once the system becomes
better organized, the 28-29 deg C waters and abundant mid-level
moisture should allow for more intensification in 24-48 h within a
weak to moderate shear environment. This is shown by most of the
intensity models, and the NHC forecast remains on the higher end of
the guidance envelope, closest to the GFS and HFIP corrected
consensus (HCCA). Later in the period, increasing deep-layer shear
and potential land interaction should result in some weakening,
although this portion of the forecast is more dependent on the
future track of the system.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Fri Oct 27 2023
For the eastern North Pacific...east of 140 degrees west longitude:
South of Central America and Mexico (EP92):
A broad area of low pressure is located a couple of hundred miles
south of the coast of Guatemala. Most of the shower and thunderstorm
activity in the vicinity of the low appears to be located well to
the west of its broad surface center. Environmental conditions are
expected to be conducive for development during the next few days,
and a tropical depression is likely to form this weekend or early
next week. Regardless of development, the low is forecast to meander
over the far eastern portion of the Eastern Pacific basin for the
next several days.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.
Southwestern East Pacific:
A weak area of low pressure located well to the south-southwest of
the southern tip of the Baja California peninsula is producing
limited and disorganized shower activity. Environmental conditions
are forecast to be marginally conducive for slow development of the
low through early next week while it drifts slowly northeastward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
