Atlantic Tropical Action 2014


Recommended Posts

Regardless of 97L, I'm more interested in the stalled front across the Gulf of Mexico. Most global models suggest an area of low pressure will try to get going as it heads towards the Texas coastline. With an upper-level low backing southwest out of the Bay of Campeche, we should see an anticyclone balloon across the region. Sneaky storm?

Agree. The WSI RPM model actually forms a small circulation with TS winds near the TX coast in about 72 hours. Bears at least keeping an eye on.

12z GFS makes things interesting for 97L. Keep in mind it does keep the LP weak and it takes a while to get going but we shouldn't pay attention to intensity this far out. Path OTS is blocked by potent storm that exits western African coast.

 

A lot can (and will) change, but still something to keep in mind.

The Euro doesn't do much with 97L (it's the vorticity near the Florida Keys), but it shows a separate entity developing from the Caribbean moving into the Gulf and affecting Texas sometime next week.  Just another place to keep an eye on, although the Caribbean has been very hostile this year.

Surprised it took people that long to post it. The GGEM and EURO show a storm. The GEFS wait until day 10 to try to spin up a weak storm.

. A tropical wave is forecast to move from western Africa into the

far eastern tropical Atlantic Ocean by early this weekend.

Conditions appear to be favorable for some development thereafter

while the system moves westward at 10 to 15 mph.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 5 days...low...20 percent.

A quick look at the next 6 to 14 days is suggesting lowering pressures across the SW Caribbean into the Western Gulf as Hurricane Cristobal exits to the NE into the N Atlantic and the Bermuda Ridge builds back into the East Coast and the Eastern Gulf of Mexico. The longer range ensemble guidance is already suggesting the potential for tropical mischief developing in the SW Caribbean Sea and moving generally NW into the Western Gulf in the first 10 days or so of September. These waters are virtually untouched with plenty of warm water with little to no shear and favorable instability. Nothing is forming at this time, but something to monitor as we begin the month of September and reach the peak of tropical development potential in the Atlantic Basin.

NHC lowered the chances of formation for 97L.  

 

A tropical wave located about 900 miles east of the Lesser Antilles
continues to produce disorganized showers and a few thunderstorms.
Environmental conditions are not expected to be favorable for
significant development during the next couple of days, but could
become more conducive by the end of the week or this weekend while
the system moves westward to west-northwestward at about 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

 

NHC is very bullish on the wave about to emerge from Africa.  Looks like a fish from the get go, but could pose a problem to the Azores if it recurves faster than anticipated.

Early morning I km Rapid Scan Visible imagery and buoy day offshore of Louisiana suggest a weak surface low may be developing SSE of Morgan City, LA. Surface winds are light out of the SE to SSE E of Houma and further W in Morgan City to Vermillion Bay, NE surface winds are observed.

Very good model support now for 97L developing in about 5 days (GFS, NAVGEM, CMC). A lot of dry air ahead of it until then.

Until the Euro comes on board, I'm not to gung ho about development.  NAVGEM and CMC are just eye candy when it comes to the tropics...wouldn't trust them farther than I can throw them.

You better hope it does not develop, the 500mb setup and analogs for this 97L scream landfalling TC. Looks like the GFS begins developing this wave around the Lesser Antilles.

Looks like it deals with less than ideal conditions and shear from a ULL.  The GFS shows a relatively weak system and dissipation by day 7.  The pattern may be one for landfalling systems, but if the systems can't organize, then it's a moot point.

Yes, however. It would be unwise to take the position of a ULL from 126 hours out with anything greater than a grain of salt.

Besides the monster tropical wave poised to move off the coast of Africa, the next place we need to look for development, in my opinion, is the western Caribbean and Western Gulf.  Models have been lowering pressures down there for the past few runs and systems have traditionally be able to ramp up quickly in the Western Caribbean/Bay of Campeche.  Should be interesting since the MJO should be favorable during that time frame.  GFS and Euro have been consistent showing something down there.
