Re: ATL : INVEST 92L
It's the wave that was following Henri, as discussed in "Talkin' Tropics" for the past day or two. Convection flared up a bit today, and there's evidence of mid-level rotation. Development chances are low, as it'll be skirting the coast of South America. Looks more impressive than Henri, though that's not a challenge.

Re: ATL : INVEST 92L
Is it a safe bet to say that this will skirt SA and hit CA and not move north due to the strong high to its north.

Just as safe of a bet it was to say that Fred's circulation would never make it past 70W. Oh, wait...
There is no such thing as a "safe bet" in the tropics in my opinion.

Re: ATL : INVEST 92L
Model plot I made. Unusual, to say the least. Would be hard for development to occur on such a track.

How can the SHIP get a 102kt hurricane with that track?

SHIPS doesn't account for land interaction. Look at the DSHPS for something more reliable.

The SHIP model (Statistical Hurricane Intensity Program) does not take into account interactions with or passage over land. The DSHP (D for "Decay") does take into account land interactions.

Shear wont be a problem but interaction with land will.

Wow a major hurricane in 120 hours, I don't buy that but it bears watching, conditions won't be that bad in the Caribbean so a tropical sotrm is possible it just needs to move north to avoid interaction with South America and to let Coriolis do its job.

Tropical wave south of Henri
A tropical wave south of Henri, just north of the coast of South America and a few hundred miles east-southeast of the southernmost Lesser Antilles Islands, has grown less organized since yesterday. Both the areal coverage and intensity of the heavy thunderstorm activity has decreased, and there are no signs of organization to the cloud pattern. This wave is under about 10 knots of wind shear, but is too close to the Equator to be able to take advantage of the Earth's spin to help it spin up into a tropical depression very quickly. Also, the wave may pull in some dry, stable air from South America as it scoots just north of the coast over the next few days. NHC is giving this disturbance a low (less than 30% chance) or developing into a tropical depression by Saturday. There are no computer models showing development of this system.

Re: ATL : INVEST 92L
Here's a surface plot. Ignore the ship reporting the northerly wind to the south of the disturbance. Note the pressure (1024mb) and temperature (30F). The ship clearly encoded its observation wrong and is plotted in the wrong location. But pressures are relatively high in the region of the wave, thus it's very rapid westward movement.

Hi, this was the first thread about this system:
viewtopic.php?f=31&t=106794
Is is possible always to post here a link to the locked discussion thread in Talkin' Tropics in the first post of a new invest? Thx.
