NATL: MELISSA - Aftermath - Discussion: Josh Morgerman video of Melissa is up

[Hypercane_Kyle]

Melissa finally has an inner core. Rapid intensification is about to begin.

Soo, after perusing the comments as best as I could to see if anyone had already posted Dr. Cowan's latest update and finding no such post, here it is:

I'm thinking tomorrow is the day it goes up, up and away.

Here's a collection of live video streams from Jamaica cameras

Folks are definitely busy there, and sometimes one of the cameras shows a supermarket (that's slammed). Another is a stream from the 200+ year old one lane flat bridge in Bog Walk over a river (probably will flood).

DRCL (which NHC 95% of the time follows) has a 135 kt point at 72 hours, and then 120 kt just inland of Jamaica at 96. This all but screams they’re going to heavily allude to the fact that Melissa will likely reach Cat 5 before making landfall in Jamaica. Probably “conservative” as well, because that’s a whole day in between borderline C5 and landfall.

Yep, they went with a 135 kt peak ahead of landfall for 5pm.

They also went with a slightly higher current intensity of 55 kt/995 mbar.

I'm starting to get scared now, NHC has 140 mph over Jamaica on the cone

[aspen]

The forecast now shows a 135 kt peak in 60 h, and there is a distinct possibility that Melissa could become a Category 5 hurricane during this time period. In fact, the latest 12z Google DeepMind ensemble distribution shows the majority of its members reaching this lofty intensity.

The NHC forecast is as close to as them saying "we think Melissa will hit Jamacia as a Category 5" as they will say for a system for that's only a tropical storm.

Chances are increasing for a historic cat 4/5 landfall on Jamaica. Let's hope Melissa somehow still misses Jamaica, but I'm starting to doubt it now: the center relocation has resolved one of the big short-term uncertainties about Melissa's behavior. She looks primed for RI so if she were to hit Jamaica perhaps the only savior could be a last-minute EWRC still in progress during landfall.

I'm not gonna act hypocritical, of course I'll also be amazed if Melissa becomes a generational storm in terms of intensity. These extraordinary showcases of nature are the reason many of us track storms. But let's all also remember that there are millions of people who are in a very dangerous situation.

I guess the good news might be if the track shifts far enough south Jamaica might stay out of the core winds for a couple days. Just a foot or two of rain to soften up the soil so the tree roots won't hold. Then with less land interaction a stronger Melissa will be ready to make a faster pass NE over the island.

Its too easy for complacency to set in with the 5 day wait before the hook NE so that might be why the Governor is holding off on the final evacuation orders.

The NHC forecast is as close to as them saying "we think Melissa will hit Jamacia as a Category 5" as they will say for a system for that's only a tropical storm.

Even when just going by what's explicitly in the forecast, it also has Melissa at 135 kts for 12 hours (60-72h), and the next forecast point 12 hours later (96h) is already inland over Jamaica (albeit just barely). Melissa can adhere to this forecast precisely while still peaking at Cat 5, or even landfallint in Jamaica as such, during any of this 24-hour period.

Edit: Weakening just before landfall is also not always a good thing. Maria's last-minute EWRC prior to hitting Puerto Rico, while avoiding a Cat 5 landfall for meteorological records, made its impacts arguably much worse.

It's also worth noting that this projection ties for one of the most aggressive intensification rates ever issued for a 55kt system, reaching the record maximum percentile for hours 12-48.

(Note that I believe this record only considers systems whose initial intensity on the advisory was exact 55 kt, not even 50 or 60, etc.)

I've decided that we are moving the curse of the "I" storm to the "M" storms

Oh that's... bad
