DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the eye of Hurricane Melissa was located  
near latitude 16.6 North, longitude 78.6 West. Melissa is moving 
slowly toward the northwest near 2 mph (4 km/h).  A slow turn toward 
the north is expected tonight, followed by a turn toward the 
northeast at a slightly faster forward speed on Tuesday.  A 
northeastward motion with a faster forward speed is expected on 
Wednesday and Thursday.  On the forecast track, the core of Melissa 
is expected to move near or over Jamaica by early Tuesday, across 
southeastern Cuba Tuesday night, and across the southeastern or 
central Bahamas on Wednesday.
 
Maximum sustained winds are near 175 mph (280 km/h) with higher
gusts.  Melissa is a category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Some fluctuations in intensity are likely 
before Melissa makes landfall on Jamaica.  However, Melissa is 
expected to reach Jamaica and southeastern Cuba as an extremely 
powerful major hurricane, and will still be at hurricane strength 
when it moves across the southeastern Bahamas.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km).
 
The minimum central pressure estimated by aircraft dropsonde data is 
909 mb (26.85 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Melissa can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.
 
WIND: Tropical storm conditions are occurring in Jamaica, and
catastrophic and life-threatening hurricane-force wind conditions
are expected to begin late tonight and continue into Tuesday. 
Within the eyewall, total structural failure is likely, especially 
in higher elevation areas where wind speeds atop and on the 
windward sides of hills and mountains could be up to 30 percent 
stronger.
 
Tropical storm conditions are expected to begin in eastern Cuba on 
Tuesday, with hurricane conditions expected to begin in the 
hurricane warning area starting Tuesday evening into Wednesday 
morning. Tropical storm conditions are expected in Haiti late 
Tuesday and Wednesday.
 
Hurricane conditions are expected in the southeastern and central
Bahamas on Wednesday.  Tropical Storm conditions are expected in the
Turks and Caicos Islands on Wednesday with hurricane conditions 
also possible on Wednesday. 
 
RAINFALL: Melissa is expected to bring rainfall of 15 to 30 inches
to portions of Jamaica and additional rainfall of 6 to 12 inches for
southern Hispaniola through Wednesday, with storm total local maxima
of 40 inches possible.  Catastrophic flash flooding and numerous
landslides are likely.
 
For eastern Cuba, storm total rainfall of 10 to 20 inches, with
local amounts to 25 inches, is expected by Monday into Wednesday
resulting in life-threatening and potentially catastrophic flash
flooding with numerous landslides.
 
Over the Southeast Bahamas, total rainfall of 5 to 10 inches is
expected Tuesday into Wednesday resulting in areas of flash
flooding.
 
For a complete depiction of forecast rainfall associated with
Melissa, please see the National Weather Service Storm Total
Rainfall Graphic, available at
hurricanes.gov/graphics_at3.shtml?rainqpf
 
STORM SURGE: A life-threatening storm surge is likely along the
south coast of Jamaica late tonight and on Tuesday.  Peak storm 
surge heights could reach 9 to 13 feet above ground level, near and 
to the east of where the center of Melissa makes landfall. This 
storm surge will be accompanied by large and destructive waves. On 
the northwest coast of Jamaica, near Montego Bay, there is the 
possibility of 1 to 3 feet of storm surge above ground level.
 
There is a potential for significant storm surge along the southeast
coast of Cuba late Tuesday or Wednesday. Peak storm surge heights
could reach 7 to 11 feet above normal tide levels, near and to the
east of where the center of Melissa makes landfall. This storm surge
will be accompanied by large and destructive waves.
 
Storm surge of 4 to 6 ft above normally dry ground is possible in
the southeastern Bahamas and Turks and Caicos Islands on Wednesday.
 
SURF: Swells generated by Melissa are expected to affect portions of
Hispaniola, Jamaica, eastern Cuba, and the Cayman Islands during the
next several days, and the Bahamas, the Turks and Caicos Islands,
and Bermuda later this week. These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.

500 PM EDT Mon Oct 27 2025

A few hours ago, data from an Air Force Reserve Hurricane Hunter 
aircraft showed that the central pressure in Melissa had fallen to 
near 906 mb. The aircraft measured maximum 700-mb flight-level 
winds of 161 kt, which supports surface winds of near 145 kt. In 
addition, low-level winds measured by a dropwindsonde in the 
northeastern eyewall support surface winds of 155 kt. During the 
time since the aircraft departed the hurricane, there has been 
little change in organization and no obvious signs that Melissa has 
weakened. Thus, the initial intensity is set at 150 kt as a blend 
of the surface wind estimates mentioned above. NOAA and Air Force 
Reserve Hurricane Hunter aircraft will again investigate Melissa 
during the next few hours.

Melissa is starting its northward turn, and the initial motion is 
now northwestward or 315/3 kt. The mid-level ridge north of Melissa 
continues to weaken as a deep-layer mid-latitude trough moves 
eastward through the southeastern United States into the 
southwestern Atlantic.  This should cause the hurricane to turn 
northward during the next 6-12 h or so at a continued slow forward 
speed.  After 18 h or so, Melissa should turn northeastward with 
a slight increase in forward speed as the mid-latitude westerly 
flow becomes the dominant steering mechanism. A continued 
northeastward motion with a significant increase in forward speed 
is expected from 36 h through the end of the forecast period. On 
the forecast track, the center of Melissa will be near or over 
Jamaica late tonight and on Tuesday, cross eastern Cuba Tuesday 
night or early Wednesday, and then move near or over the Bahamas 
and the Turks and Caicos on Wednesday.  After that, the cyclone 
could reach the vicinity of Bermuda on Thursday night. The track 
guidance envelope has nudged a little to the west and north since 
the previous advisory, and the new forecast track is also a little 
to the west and north of the previous track.

Some fluctuations in intensity are likely during the next 12-24 h
due to the possibility that Melissa will start an eyewall 
replacement cycle (ERC). However, the previous aircraft data showed 
no evidence that an ERC had started, and it is possible that the 
upcoming aircraft may find Melissa is stronger than 150 kt. 
Regardless, even with an ERC it is unlikely that Melissa will 
weaken significantly before reaching Jamaica, and there is no 
practical difference in Melissa making landfall at category 4 or 5 
intensity, since both categories produce catastrophic wind damage. 
After reaching Jamaica, a combination of land interaction and 
increasing southwesterly shear should cause weakening, although 
Melissa is still forecast to be a major hurricane when it reaches 
Cuba.  Once over the Atlantic, stronger shear should cause more 
substantial weakening, and Melissa is expected to become 
extratropical by the end of the forecast period as it interacts 
with a large baroclinic low over the north Atlantic.  The new 
intensity forecast has minor adjustments from the previous and 
again follows the trend of the intensity consensus.
 
 
Key Messages:
 
1. Jamaica:  Remain in your safe shelter and do not venture 
outside. Catastrophic, life-threatening flash flooding and numerous 
landslides are expected through Tuesday. The eyewall’s destructive 
winds may cause total structural failure, particularly in higher 
elevations, leading to widespread infrastructural damage, prolonged 
power and communication outages, and isolated communities. Along the 
southern coast, life-threatening storm surge and damaging waves are 
anticipated through Tuesday. 
 
2. Haiti and the Dominican Republic:  Catastrophic and 
life-threatening flash flooding and landslides are expected across 
southwestern Haiti and southern portions of the Dominican Republic 
through midweek.  In Haiti, extensive infrastructural damage and 
isolation of communities is likely. Tropical storm conditions are 
expected late Tuesday and Wednesday.
 
3. Eastern Cuba:  Heavy rainfall with life-threatening and 
potentially catastrophic flash flooding and landslides is expected 
to begin tonight.  Life-threatening storm surge and damaging winds 
are expected late Tuesday and Tuesday night.   Preparations should 
be rushed to completion.
 
4. Southeast and Central Bahamas and the Turks and Caicos: Hurricane 
conditions, life-threatening storm surge, and heavy rainfall are 
expected across portions of the southeast and central Bahamas on 
Wednesday. Residents should follow advice given by local officials 
and be sure to have preparations complete by Tuesday night.  
Tropical storm conditions, heavy rains, and a significant storm 
surge is expected in the Turks and Caicos Islands on Wednesday.

741 PM EDT Mon Oct 27 2025

.SYNOPSIS...
An upper level trough will remain across the region early week
while surface high pressure gradually builds south across Quebec
through midweek. A large low pressure system will cross the
region Friday and move north of Maine into the weekend.

&&....

.......LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Moisture from Hurricane Melissa will likely be entrained into
occluding surface low heading up into the northeast U.S. Vertically
stacked low looks to be located over wrn NY/PA at 00z Friday.
Pressure gradient tightens between deepening sfc low and strong high
pres off of the Maritime. Depending on how strong ridge axis over
ern areas is will determine how quickly rain can move in over entire
region. Given latest operational models and ensemble guidance, have
gone with 90-100% chance of stratiform rain late Thursday night
through the day on Friday. Elevated instability looks to be possible
over the Downeast coast on Friday, resulting in a slgt chc of
tstms in the afternoon.

PW values with the system will rise toward the 95th percentile late
Thursday night into Friday. Total rainfall amounts look to be
between 1-2 inches with this system, with isolated higher amounts
possible. Southeasterly low-level jet between 35-50kts looks to move
twd the coast on Friday morning, depending on track of sfc low. Have
not made adjustments to wind fcst as still some variations in the
track of low, thus low-level jet but expect winds will need to be
tweaked in the coming days. It/s looking more and more likely that
Halloween will end up being a bagful of tricks.

Wrap-around showers will exist thru the weekend over the north thru
the end of the period. Temperatures will slowly diminish below
normal values into early next week.....
