Subtropical Storm Karen Discussion Number   1
NWS National Hurricane Center Miami FL       AL112025
300 AM GMT Fri Oct 10 2025

Over the last 12-18 hours, NHC has been monitoring a small area of 
low pressure (AL96) embedded in a much larger upper-level trough, 
located about 400 n mi to the northwest of the northernmost Azores 
Islands. The system was originally a frontal low that quickly became 
occluded early on 8 October. Since that time, the low has been 
gradually shedding its remaining frontal features as shallow to 
moderate convection formed near the center. Earlier today, there was 
a Sentinel-1A Synthetic Aperture Radar (SAR) pass that indicated the 
system no longer was attached to frontal boundaries and had a 
contracted radius of maximum wind of 20 n mi. Since that time, the 
convective cloud tops have cooled to -50 to -55 C around the center, 
with a distinct warm spot seen near the center. A recent WSFM 
microwave pass also indicated a nearly closed cyan ring on the 
37-GHz channel. 00 UTC subjective satellite classifications on the 
system were a ST1.5/25-30 kt from TAFB, and a T3.0/45 kt from SAB. A 
blend of all of these various data points indicate that the system 
has made the transition to Subtropical Storm Karen. The initial 
intensity is set at 40 kt, in agreement with a recently received 
scatterometer pass which had a peak wind of 38 kt. This also matches 
the special 02 UTC fix of ST 2.5/35-40 kt received from TAFB.

The subtropical storm is moving slowly northeastward, estimated at 
050/8 kt. Karen is already well established in the mid-latitude 
westerlies for being at such a high latitude, and is likely to be 
caught up by another mid-latitude trough that is digging in from the 
west. The track guidance in in pretty good agreement on a 
northeastward motion with a gradual acceleration over the next 24-36 
hours, and the NHC track forecast is roughly in the middle of the 
guidance envelope, close to the simple and corrected consensus 
aids. 

While Karen has made the transition to a subtropical storm, it still 
remains fully embedded in a large upper-level low, so large in fact 
that it has helped the shear over the system remain fairly low and 
has enabled the convection to coalesce near the center. Very cold 
upper-level temperatures also appear to be contributing to the 
convective vigor, allowing cloud tops of -50 C to persist near the 
center. However, even colder sea-surface temperatures lie ahead of 
Karen's path, and it seems like the system only has about a day or 
so before it is quickly overtaken by the next mid-latitude trough. 
The global models show the small cyclone opening up into a trough by 
48 h, and it is also possible the system could become post-tropical 
before then if it loses its current organized convection. This 
intensity forecast is in general agreement with the mean of the 
intensity guidance.

Tropical Storm Jerry Discussion Number  11
NWS National Hurricane Center Miami FL       AL102025
1100 PM AST Thu Oct 09 2025

Jerry remains a disheveled tropical storm this evening. Most of the 
deep convection is displaced to the southeast of the low-level 
circulation, which continues to run out ahead due to continued 
northwesterly vertical wind shear. Air Force reconnaissance 
observations indicate a highly asymmetric wind field, with the peak 
850 mb flight level winds of 56 kt in the northeastern quadrant, and 
very little wind on the western side of the circulation. The flight 
level winds support lowering the initial intensity to 50 kt this 
advisory. The surface pressure has been rising as well, with the 
latest dropsonde data supporting a minimum value of 1005 mb.
 
Jerry appears to finally be moving northwestward now, estimated at 
315/15 kt. The track reasoning remains about the same as this 
afternoon, as Jerry's track should gradually bend more poleward as 
it moves along the western side of a subtropical ridge. On the 
forecast track, Jerry is making its closest approach to the Leeward 
Islands currently, and its asymmetric wind field means that the 
majority of the stronger winds will stay east of the island chain. 
Early next week, a faster eastward or east-northeastward motion is 
forecast in the mid-latitude westerlies. Jerry is expected to pass 
east of Bermuda in a few days, and given its expected eastward 
asymmetry, significant impacts still remain unlikely there. The NHC 
track forecast is quite similar to the prior one, and is a rough 
blend between the slower and further west HCCA guidance and the 
faster and further east Google DeepMind Mean (GDMI). 

The tropical storm is struggling mightily against the unfavorable 
northwesterly vertical winds shear, and its current poor structure 
also does not bode well for future short-term intensification. After 
the storm passes the northern Leeward Islands, the vertical wind 
shear does decrease to 10-15 knots, but given the current structure, 
it may take some time for the system to recover. Nonetheless, 
gradual intensification is shown beginning in 36 hours, though the 
intensity forecast is lower than the previous advisory. Shear 
increases towards the end of the forecast and sea-surface 
temperatures decrease as Jerry recurves into the mid-latitude 
westerlies, and some weakening is shown again in 120 h. This remains 
a low confidence intensity forecast, and on the high side of the 
overall guidance envelope. 

The most significant hazard expected from Jerry over the next few 
days is heavy rainfall, even after Jerry passes to the north due to 
its current structure with most of the significant weather to the 
south and east of the tropical cyclone. 
 
 
KEY MESSAGES:
 
1. Tropical storm conditions are expected in the warning area and
are possible in the watch area this evening through Friday morning.
 
2. Heavy rainfall will impact portions of the Leeward Islands,
British Virgin Islands, U.S. Virgin Islands, and Puerto Rico through
Friday, which could result in flash flooding, particularly in urban
areas and in steep terrain.

tonight through Friday.  A turn toward the northeast is expected 
Friday night.  On the forecast track, the center of Priscilla is 
expected to remain offshore of the coast of Baja California Sur, and 
dissipate by Saturday.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. 
Weakening is forecast, with Priscilla expected to become a 
post-tropical remnant low on Friday and dissipate by Saturday.
 
Tropical-storm-force winds extend outward up to 105 miles (165 km)
from the center.
 
The estimated minimum central pressure is 995 mb (29.39 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
RAINFALL:  As Priscilla moves offshore of the west coast of Baja
California, up to an inch of rain is expected across the Baja
California peninsula.  For the southwestern United States, 2 to 4
inches of rain, with local storm total maxima to 6 inches, are
expected across portions of central and northern Arizona, southern
Utah, and southwest Colorado through Saturday.  Flash flooding is
likely in  portions of central Arizona, with scattered areas of
flash flooding expected across the remainder of Arizona, southern
Utah, southwest Colorado, and far northwest New Mexico.
 
For a complete depiction of forecast rainfall and flash flooding
associated with Priscilla, please see the National Weather Service
Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_ep1.shtml?rainqpf
 
SURF: Large swells generated by Priscilla are affecting the Pacific
coast of Baja California Sur.  These swells are likely to cause
life-threatening surf and rip current conditions, in addition to
some coastal flooding. Please consult products from your local
weather office.

Tropical Storm Priscilla Discussion Number  22
NWS National Hurricane Center Miami FL       EP162025
800 PM PDT Thu Oct 09 2025
 
Priscilla has proven to be a resilient tropical cyclone this 
evening, despite moving over cool waters near 24C.  Since the 
previous advisory, the system has maintained a well-defined curved 
band that wraps more than halfway around the center.  The latest 
subjective Dvorak intensity estimates from TAFB and SAB are 2.5/35 
kt and 3.5/55 kt, respectively.  Based on a blend of these data, 
along with the large area of 40-kt winds noted in a scatterometer 
pass earlier today and some improvement in the cyclone’s structure, 
the initial intensity has been increased to 45 kt.

Priscilla is moving north-northwest, or 345 degrees, at 7 kt.  A 
turn toward the north and a decrease in forward speed are expected 
tonight through Friday as the cyclone moves between a longwave 
trough to its northwest and a mid- to upper-level ridge over Texas 
and northern Mexico.  A turn toward the northeast is forecast after 
24 hours as the system becomes shallower and increasingly steered by 
the low-level flow.  The updated NHC track forecast lies close to a 
blend of the previous advisory and the multi-model consensus aids.

Priscilla will be moving over progressively cooler waters and into a 
drier mid-level environment during the next day or so, while also 
encountering increasing southwesterly vertical wind shear.  These 
factors should result in steady weakening.  Simulated satellite 
imagery from the GFS and ECMWF indicates that Priscilla will lose 
its deep convection within about 12 hours, with both models showing 
the system degenerating into a trough by 48 hours, if not sooner. 
The NHC intensity forecast calls for Priscilla to become a 
post-tropical remnant low within 24 hours, with dissipation expected 
by 48 hours.
 
Remnant moisture associated with Priscilla remains the primary 
hazard across portions of southwestern United States.  Heavy 
rainfall and flash flooding are likely into the weekend over parts 
of central Arizona, with scattered areas of flash flooding possible 
across the remainder of Arizona, southern Utah, southwestern 
Colorado, and far northwestern New Mexico.  Please monitor forecasts 
and updates from local National Weather Service offices in the 
southwest U.S. at weather.gov and from the Weather Prediction Center 
at wpc.ncep.gov.

HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Raymond can be found in the Tropical 
Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header 
WTPZ42 KNHC. 

WIND: Tropical storm conditions are expected within the warning
area through today.
 
RAINFALL: Outer bands from Raymond will bring heavy rain to portions
of southwestern Mexico through Saturday.  Across coastal portions
of Guerrero and Michoacán, rainfall amounts of 2 to 4 inches are 
expected, with local amounts of 6 inches or more in Michoacán. This 
rainfall will bring a risk of flash flooding, especially in areas of 
higher terrain.  Across coastal portions of Oaxaca, Colima, and 
Jalisco, rainfall amounts of 1 to 2 inches are expected.  Moisture 
from Raymond will also bring the potential for additional heavy 
rainfall over portions of the Southwest U.S. early next week.
 
For a complete depiction of forecast rainfall and flash flooding 
associated with Raymond, please see the National Weather Service 
Storm Total Rainfall Graphic, available at

Tropical Storm Raymond Forecast Discussion Number 3

Issued at 900 PM CST Thu Oct 09 2025 000

Tropical Storm Raymond Discussion Number   3
NWS National Hurricane Center Miami FL       EP172025
900 PM CST Thu Oct 09 2025
 
A couple of recent microwave overpasses indicate that Raymond's
cloud pattern has changed little during the past several hours.
Images show fragmented curved bands surrounding the elongated (SE
to NW) surface circulation.  The cyclone may be struggling a bit
due to the large deep convective complex (-82C cloud tops) located
to the northwest of the center, which could be disrupting the
cyclone's low-level flow.  The subjective and objective technique
intensity estimates range from 30 to 45 kt, and a recent UW-CIMSS
SATCON analysis estimated the intensity to be 35 kt.  Using a blend
of these data, the initial intensity is held at 40 kt.
 
The statistical-dynamical Decay-SHIPS intensity guidance and the 
global models indicate that Raymond will be battling stiff easterly 
vertical shear during the next couple of days, which should hamper 
significant development.  Subsequently, only modest strengthening is 
forecast through Friday.  Afterward, an increasingly hostile 
thermodynamic environment should result in a weakening trend through 
the period.  Accordingly, Raymond is expected to degenerate to a 
remnant low on Sunday while emerging over the Gulf of California, 
and ultimately opening up into a trough by early next week.  The NHC 
intensity forecast is based on a close agreement of the FSSE, HCCA, 
and IVCN intensity aids.
 
Raymond's center has been difficult to find this evening, and the 
initial motion is an estimated west-northwestward heading, or 290/13 
kt.  A mid-tropospheric high, anchored over northern Mexico, should 
steer Raymond toward the west-northwest to northwest, while 
paralleling and remaining just offshore of the coast of southwestern 
Mexico, through Friday evening.  Afterward, Raymond is forecast to 
turn north-northwestward, then northward in response to an 
amplifying mid-latitude trough moving over the southwestern United 
States.  The various consensus models and the Google DeepMind 
ensemble mean were used as a basis for the official track forecast. 
 
 
KEY MESSAGES:
 
1.  Tropical storm conditions are expected along portions of the
coast of southwestern Mexico through late Friday.  Interests in
southern Baja California Sur should monitor the progress of the
system.
 
2.  Heavy rainfall associated with Raymond will impact coastal 
sections of southwestern Mexico through Saturday, which could result 
in flash flooding, particularly in areas of higher terrain.
