Hurricane Melissa

[dan11295]

Only positive is that Melissa might be far enough west to keep Kingston area out of the eyewall winds and the south coast of Jamaica isn't that surge prone. Biggest threat has been and continues to be the flooding as hazwoper just mentioned. Farther west track unfortunately subjects more of the island to very high rainfall totals and the NNE trajectory is unfortunately very favorable to squeezing out the moisture via orographic lifting.

There’s resorts on the west part of the island too. Might be worse vs where it’s currently forecasted to go.

Which presents an even more dire situation for those dense coastal areas. Based on a more west track, storm surge would be maximized. No matter the scenario or potential tracks left on the table, each one is catastrophic or devastating for Jamaica. Also, a more west track increases the likelihood of a peak intensity landfall being it will be over warmer waters longer.

That is true. As far as intensity and surge impacts but the more west it goes the more rural areas the core of hurricane will impact. However the surge and extreme rainfall impacts will still be impactful well east into more populated areas.

The wind field seems to be expanding a bit per recon 

[Radtechwxman]

Are they finding any higher winds along with these big pressure drops? 

[dbullsfan]

i hope all those homophobes drown 

You might want to sit this one out. I by no means support any type of homophobic behavior but this is an absolutely disgusting post. This is an extremely dangerous storm and there is a good chance people will die.

Also the various cruise ports, which Jamaica relies a ton on for tourism.

Latest recon pass found 128 kts flight level in the right quad, so that has been pretty steady.

I hope it undergoes a prolonged ERC soon, which will weaken Melissa.

taking a SW dip?

Maybe just a wobbly, considering how strong it is, like  top would?

Yeah it looks like a wobble SW. Not that it matters at this point but any further south and it'll be tapping into one of the deepest pools of OHC in the basin. 

[Wild Weather Monger]

Yep.  a bit of southerly component this evening.  Also, it appears to have increased its forward speed a bit.

Small chance Melissa gets far enough west before re-curving and just misses Jamaica to the west if this movement persist a bit longer than expected.

Seems like pressure has been steadily dropping all day but winds struggling to catch up. Based on these pressures and satellite look I would think this would be cat 5 now but feel like something has been holding back the winds some.

Is it me or does it look like it’s weakening just a hair?

[IMADreamer]

I'm really not seeing weakening.  It's throwing up hot towers like crazy.

Could be a little bit of upwelling too. She's been crawling along

 It isn’t just upwelling that cools the waters at or near where a hurricane crosses: it also cools due to the conservation of energy (potential energy from warm water transitions to kinetic (wind) energy of the storm/heat engine), cooling from raindrops (I assume this factor is relatively minor), and cooling from cloudcover blocking the sun:

Hurricanes cool the ocean by acting like "heat engines" that transfer heat from the ocean surface to the atmosphere through evaporation. 

Cooling is also caused by upwelling of cold water from below due to the suction effect of the low-pressure center of the storm.

Additional cooling may come from cold water from raindrops that remain on the ocean surface for a time. 

Cloud cover may also play a role in cooling the ocean by shielding the ocean surface from direct sunlight before and slightly after the storm passage.

All these effects can combine to produce a dramatic drop in sea surface temperature over a large area in just a few days.

That would be incredible.

Model consensus is sold on it moving NNE into western Jamaica. These wobbles aren't uncommon and will correct themselves.

It looks as good as it ever has. Very cold cloud tops now rotating around core. I would be shocked if we didn't have a Cat 5 by morning.  

[Radtechwxman]

Apparently hurricane hunters are struggling to hit the eye because it's small and turbulence. Hopefully they get a good sample before having to head back. 

[WxSynopsisDavid]

Pressure holding steady and no longer tanking. Looking at TDR, perhaps an outer eyewall trying to go up. Looks like an ERC or MERC about to commence soon.

[Floydbuster]

What a monster. Looks like it might do an ERC in the next 12 hrs or so. Not good, because then the wind field will expand further.
