Except 11 hours late. It was not a 140 mph storm when they said it was at 5am. It strengthened into a 140 mph storm throughout the day.

So what about the previous 10 recon passes today that did not confirm the NHC intensity?  Did those not count?  The NHC even said in their discussion their estimate might be generous.  It's no big deal.  It was likely going to strengthen more at some point today/tonight.

Melissa absolutely looks better now than it did this morning.  Much sharper edges of the eye and CDO.

People were claiming the intensity a bust in this flight bc of a NW-SE pass

Next recon is scheduled to be in there around 2330z.  Every 6 hours there will be a new recon plane.

This is going cat 5. Eye has completely cleared and is perfectly symmetrical. Beast mode activated

It appears the Google DeepMind model will be one of the winners again.  Several other models kept wanting to bring Melissa farther north, in between Haiti and Jamaica or into eastern Jamaica from the east/southeast.  The Google ensembles never budged from the wsw/west track to the south of Jamaica.

Just slogging due east. WEST

Hurricane Melissa Discussion Number  22
NWS National Hurricane Center Miami FL       AL132025
500 PM EDT Sun Oct 26 2025
 
After an earlier pause in intensification, this afternoon's Air 
Force Reserve reconnaissance mission has found Melissa intensifying 
again. The minimum pressure has fallen 12 mb from this morning 
NOAA-P3 mission, with the last dropsonde indicating a minimum 
pressure of 941 mb, and the plane reported a shrinking eyewall down 
to 6 n mi in diameter. In addition to the low pressure, the 
satellite presentation of Melissa remains very impressive, with 
1-minute visible satellite images from a GOES-19 meso-sector showing 
a very clear eye with a stadium effect. The eye temperature on water 
vapor imagery has continued to warm, while the thick ring of eyewall 
cloud tops remains between -75 to -80 C around the eye. The 
presentation of Melissa on radar reflectivity from Kingston, Jamaica 
has also improved, though there still appear to be hints of a moat 
forming around the inner eyewall, though without an obvious 
secondary eyewall formation yet. Subjective Dvorak CI-numbers from 
both SAB and TAFB were T7.0/140 kt, with objective satellite 
estimates between 132-143 kt. However, Melissa's peak winds from the 
last couple of recon missions have been lagging the satellite-based 
estimates. The last fix had peak 700 mb flight level winds of only 
129 kt, but a dropsonde launched in the north eyewall also reported 
a 500 m layer average of 142 kt, with an earlier dropsonde in the NE 
eyewall with a surface wind gust of 131 kt. This data is enough to 
raise the maximum sustained winds of 125 kt, and given the satellite 
presentation, this could be conservative. 

Melissa continues to move slowly westward, estimated at 270/4 kt. 
The hurricane has been moving a little faster to the west today, and 
this motion will likely continue for another 12-18 hours while the 
narrow mid-level ridge to the north remains in place. Soon, a 
short-wave trough will be moving into the SE United States, and this 
feature should create a weakness that Melissa will turn 
sharply northeast into, as it gradually accelerates. The track 
guidance has shifted a little westward again this cycle, and the NHC 
track forecast was nudged a little west again, but still shows 
landfall on Tuesday morning along the south coast of Jamaica. There 
remain some timing differences thereafter, but a second landfall is 
anticipated along the southeastern Cuba coast by Tuesday night or 
early Wednesday morning. As Melissa then accelerates into the 
southwestern Atlantic, it will move through the Bahamas and 
potentially approach Bermuda by the day 4-5 time frame, with a 
reinforcing trough helping to kick it farther out to sea. The latest 
NHC track forecast is a little west in the first 24-60 h, but falls 
back near the previous forecast track thereafter. The track is 
roughly a blend of the reliable HFIP Corrected Consensus Approach 
(HCCA) and Google Deep Mind ensemble mean (GDMI). 

Now that Melissa is intensifying again, it seems more clear that the 
earlier pause in intensification was a temporary oscillation, and 
the hurricane now appears poised to intensify more in the 
short-term. The latest NHC intensity forecast shows a little more 
intensification in 12 h, but continues to show a peak intensity of 
140 kt, which is supported by HAFS-B which shows landfall of Melissa 
as a catastrophic Category 5 hurricane. The Google DeepMind ensemble 
members also continue to indicate this peak, with now 48/50 members 
reaching this lofty intensity. However, inner-core processes like 
ERCs could occur at any time, and the current small eye of Melissa 
likely suggests an ERC could begin in the next 24 hours or so, 
though it is very difficult to predict these occurrences with much 
skill. After landfall in Jamaica, Melissa will likely weaken some 
due to the interaction with that Island's high terrain, but it is 
still expected to be a major hurricane when crossing the Cuba 
coastline on Tuesday night. After emerging into the southwestern 
Atlantic Ocean, increasing vertical wind shear should continue 
gradual weakening through the end of the forecast, with the 
possibility that Melissa could start extratropical transition by day 
5. The NHC intensity forecast continues to be on the high side of 
the guidance, but falls closer to the HCCA and IVCN aids towards the 
end of the forecast period.

I believe you mean due west 

[SnoSki14]

Satellite presentation alone would suggest a near cat 5 now. Very impressive 

[dbullsfan]

That is one of the more impressive eyes I can remember. Would not want to be anywhere near Jamaica right now.

Jamaica's weather service not anywhere close to positioned to handle this kind of event, site often not loading or slowly loading for me. Eyes of the world are trying to watch right now... amazing event about to unfold here.

On Friday I listened to a briefing from the chief meteorologist for the Jamaican weather service and, at that time, the *center* of the NHC cone kept Melissa skirting around the western side of Jamaica. And in his briefing he stated "Right now, Jamaica should be protected as Melissa goes around the island". Like no sir, that's THE CENTER of the storm. Impacts are wayyyy outside the cone. I audibly gasped at his statement. I really really hope they are prepared for this.
