.SYNOPSIS...
Surface high pressure will remain north of the region through
mid week, while an upper trough remains across the region. Low
pressure will approach Thursday, cross the region Friday, then
move north of Maine through the weekend.

&&......

........SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Thursday through Friday, a low pressure system developing over
the mid-Atlantic will move northward and cross the state of
Maine. Model forecasts are beginning to come to a consensus on
the track, with the low center moving from south to north across
the state. This will bring a band of precipitation across the
area beginning Thursday night, although showers will develop
ahead of the main front on Thursday afternoon. This system will
tap into the same moisture feed currently fueling Hurricane
Melissa. Although Melissa will be far enough to the east to have
minimal impacts on Northern Maine, the tropical moisture will
increase rain rates with this particular storm. QPF values are
ranging from 1.0 to 2.5", with around 1.5" the most likely for
northern counties and 2.0" more likely towards Bangor and the
Downeast Coast. Some question remains as to the strength of the
winds in the warm sector ahead of the front. CAMs are indicating
a strengthening low level jet; however currently thinking that
mixing down these winds is slightly less likely than in a cold
air advection environment. Therefore, expect gusty southeasterly
winds, in particular along the coast, but right now winds
should remain below advisory level (<40 mph).

As the low moves through on Friday, the first band of precip
will move northeastward, but then be followed by more convective
activity Friday afternoon and evening. Winds during this period
will also switch to a more westerly direction behind the low.
Although the LLJ associated with the warm front will have moved
eastward, the convective nature behind the low should pull more
gusty winds to the surface, and winds/wind gusts will increase
Friday night.

Temperatures during this period will be warm with the front on
Thursday night and Friday, then cooling behind the front Friday
night. Gusty winds will make for brisk conditions on Friday
night, mainly across the north and west. Trick or treaters, and
their chaperones, should plan accordingly.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
The center of low pressure will have moved off to the northeast
by Saturday morning after having considerably deepened.
Ensemble solutions show the low reaching somewhere between 960
and 980 mb. A strong pressure gradient is expected to develop
on the backside of the departing system which should result in
strong westerly winds during the day. Moisture wrapping around
the low in combination with some shortwave energy behind the
departing upper-trough is likely to contribute to the
development of some lingering showers throughout Saturday,
especially in the north, and may continue through Sunday. Some
snow showers may mix in Saturday night depending on how much
cold air is brought in behind the system.

Weak high pressure will likely develop over the area Monday in
response to an approaching upper-level shortwave ridge. This
should lead to mostly dry conditions. Some signal in the
ensemble solutions for another storm sometime mid next week but
too much uncertainty to be more definitive at this time.

DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Melissa was 
located near latitude 18.8 North, longitude 77.2 West. Melissa is 
moving toward the north-northeast near 8 mph (13 km/h).  A turn 
toward the northeast is expected later this evening, and a faster 
motion in that direction is expected on Wednesday and Thursday.  On 
the forecast track, the core of Melissa is expected to move over 
eastern Cuba later tonight and early Wednesday morning, move across 
the southeastern or central Bahamas later on Wednesday, and approach 
Bermuda Thursday and Thursday night.
 
Maximum sustained winds are near 125 mph (205 km/h) with higher
gusts.  Melissa is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Melissa is expected to remain a powerful 
hurricane when it moves across Cuba, the Bahamas, and near 
Bermuda. 
 
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 estimated minimum central pressure based on data from a 
NOAA Hurricane Hunter aircraft is 950 mb (28.06 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: The damaging winds are expected to gradually subside across 
Jamaica, but it is advised to remain in a safe shelter until 
sunrise.
 
Hurricane conditions are expected in the warning area in Cuba 
later tonight through Wednesday morning. Tropical storm conditions 
are expected in Haiti tonight and Wednesday.
 
Hurricane conditions are expected in the southeastern and central
Bahamas on Wednesday. Tropical storm conditions are expected and
hurricane conditions are possible in the Turks and Caicos Islands on
Wednesday.
 
Hurricane conditions are possible on Bermuda Thursday and Thursday
night.
 
RAINFALL: Melissa is expected to bring an additional 6 to 12 inches
across Jamaica, where storm total amounts will be between 12 to 24
inches. Isolated areas near 30 inches will be possible over
mountainous terrain. Ongoing catastrophic flash flooding and
numerous landslides will continue through Tuesday night.
 
For eastern Cuba, storm total rainfall of 10 to 20 inches is
expected through Wednesday, with local amounts to 25 inches expected
over mountainous terrain. This will cause life-threatening and
potentially catastrophic flash flooding with numerous landslides.
 
Over the Southeast Bahamas, storm total rainfall of 5 to 10 inches
is expected through Wednesday, which will result in areas of flash
flooding. For the Turks and Caicos, rainfall totals of 1 to 3
inches are expected. Heavy rain may begin to affect Bermuda Thursday
night.
 
Over southern Hispaniola, additional rainfall of 2 to 6 inches is
expected through Wednesday, with storm total local maxima of 40
inches possible.
 
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: On the northwest coast of Jamaica, near Montego Bay,
there is the possibility of 2 to 4 feet of storm surge above ground
level. Storm surge flooding on the southern coast of Jamaica should
subside later tonight.
 
There is a potential for significant storm surge along the southeast
coast of Cuba through early Wednesday. Peak storm surge heights
could reach 8 to 12 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. Minor coastal
flooding is possible in bays and inlets along the north coast of
eastern Cuba.
 
Storm surge of 5 to 8 ft above normally dry ground is possible in
the southeastern Bahamas on Wednesday, and 2 to 4 ft above normally
dry ground in the Turks and Caicos Islands on Wednesday.
 
Minor coastal flooding is expected along the coast of Haiti.
 
SURF: Swells generated by Melissa are expected to affect portions of 
Hispaniola, Jamaica, eastern Cuba, and the Cayman Islands during the 
next day or so, causing life-threatening surf and rip current 
conditions. These swells will reach the Bahamas and the Turks and 
Caicos Islands overnight, and Bermuda later this week. Please 
consult products from your local weather office.

Hurricane Melissa Discussion Number  30
NWS National Hurricane Center Miami FL       AL132025
500 PM EDT Tue Oct 28 2025
 
The eye of Melissa made landfall in western Jamaica near 17Z with
maximum sustained winds estimated at 160 kt and a central pressure
near 892 mb. Since that time, the hurricane has been weakening over
the mountains of western Jamaica with the eye disappearing and some
warming of the convective cloud tops. Based on these changes, the
initial intensity has been reduced to a highly uncertain 125 kt.
NOAA and Air Force Reserve Hurricane Hunter aircraft are scheduled
to investigate Melissa this evening to provide better information
on how much it has weakened. It should be noted that while
Melissa's landfall intensity is among the strongest ever recorded
in the Atlantic basin, it will take extensive post-analysis to
determine exactly where it ranks among landfalling Atlantic
hurricanes.
 
The initial motion is now 025/7. A turn toward the northeast with
an increase in forward speed is expected this evening, and this
should bring the center near or over southeastern Cuba late tonight
or early Wednesday. After that, an even faster motion toward the
northeast should bring the center through the southeastern and
central Bahamas on Wednesday and near Bermuda Thursday or Thursday
night. After passing Bermuda, the cyclone should continue quickly
northeastward into the north Atlantic. The track guidance envelope
has shifted a little to the left (north and west) through 72 h
since the last advisory, and the new forecast track during this
time is also shifted a little to the north and west.
 
While the center of Melissa is now emerging over water, it will 
probably not re-intensify significantly before landfall in Cuba due 
to the limited amount of time before landfall and an upper-level 
wind environment that is becoming less favorable. Based on this, the
intensity forecast calls for little change in strength before
Melissa reaches Cuba.  After leaving Cuba, Melissa should encounter
increasing southwesterly vertical shear that should cause gradual
weakening, although the cyclone should still be at hurricane
strength when it passes near Bermuda. Based on global model
guidance, Melissa is forecast to become a strong extratropical
cyclone over the North Atlantic by 96 h.
 
 
Key Messages:
 
1. Jamaica: Remain in a safe shelter tonight. Damaging winds will
continue over portions of Jamaica this evening. Catastrophic flash
flooding, and landslides, are expected across the island tonight
with widespread infrastructure damage, power and communication
outages, and isolated communities.
 
2. Haiti and the Dominican Republic: Catastrophic flash flooding
and landslides are expected across southwestern Haiti and southern
portions of the Dominican Republic during the next day or so. In
Haiti, extensive damage and isolation of communities is likely.
Tropical storm conditions are expected later today and Wednesday.
 
3. Eastern Cuba: Heavy rainfall, flash flooding and landslides are
expected soon. Life-threatening storm surge and damaging winds are
likely to begin later today. Seek safe shelter.
 
4. Southeastern and Central Bahamas and the Turks and Caicos:
Hurricane conditions, life-threatening storm surge, and heavy
rainfall are expected across portions of the southeastern and
central Bahamas on Wednesday. Complete preparations by tonight and
follow local official guidance. Tropical storm conditions, heavy
rains, and significant storm surge are expected in the Turks and
Caicos Islands on Wednesday.
 
5. Bermuda: Hurricane conditions and heavy rainfall are possible in
Bermuda beginning Thursday or Thursday night where a Hurricane
Watch is now in effect.
