Hurricane Melissa

Looks like that latest track takes Melissa right on the cusp or over the highest OHC (Oceanic Heat Content) that @Blountwolf pointed out yesterday
 
WTH? My guess was literally on point!!!

5:00 PM EDT Sat Oct 25
Location: 16.6°N 75.5°W
Moving: W at 3 mph
Min pressure: 974 mb
Max sustained: 90 mph
 
What's the surge potential around Kingston?

Considering all the factors that determine surge (duration of onshore winds, size of fetch, strength of fetch, bathymetry of the coastline, etc) and the most likely approach angle, Kingston could be facing a major storm surge disaster.

At this time it appears Melissa will not be a particularly large hurricane in terms of wind field, which is perhaps the only mitigating factor.

Is 20+ feet of surge somewhere near Kingston a possibility here?

9-13 feet is mentioned in the current public advisory, but that was revised up from 5-10 last advisory
 
Shear now dropping in front of her.

Yeah - the track toward the hot pools is not giving me much hope for a miracle.

Jamaica has the benefit with storm surge of being fairly mountainous compared to many islands. Still, definitely going to be some places go under.

And if landfall is Hunters Village or west, that will mean a lot of hours of it wind piling water into those bays.
 

And an interesting coincidence is that if Melissa does become a Category 5 hurricane, it would be the third one of this season, which would be the first time since 2005 that the Atlantic officially produced more than two Category 5 hurricanes.

Been thinking about that as well.
 
The mountains are pretty much irrelevant to the surge threat here since much/most of the population is clustered in the flat, low-lying areas near the coast.
I've got to disagree with you there, at least in terms of the permanent population. Most of Kingston, all of Saint Catherine, etc. - all up off the water enough that surge isn't a huge risk, at least according to the model I posted above. Reality may differ from modeling, of course. The tourist areas are what are clustered in the low-lying areas near the coast. Unfortunately, the permanent population mostly living up off the water isn't going to help them from being shredded by the winds, which are going to be enough to cause destruction island-wide, I'm afraid.

Do the blacks just mean the scale is maxed out?
Yes.
 
Been thinking about that as well.
It’s just so interesting that the Atlantic has been able to spit out Cat 5s like it’s nothing this year, even with the issues this season has faced.
