Final: 15/8/4 with two major hurricane landfalls.

i'm 14/7/4...could be a dead late season (Oct//Nov) if weak Nino does end up popping. If we manage a La Nada in Fall we probably get 16+ but looking at SST's as of today I think we probably get borderline weak Nino conditions in EPac.

Is Harbourton's satellite image causing a password prompt for anyone else?

In any case, the place to watch is the Western Caribbean next week. It'll take a while for anything to form, but we might have something by next weekend.

Yes

Yeah, I just had that pop up when I came into the thread.

Sorry about that guys. I thought I could just copy image and paste without password rights - my bad. Anyway, there are some.SST anomolies on the plus side off the coast of Africa stretching into central Atlantic... Also warm SSTs from Delaware and eastern Maryland shore to Long Island showing up.

That SSTA graph is better than I'd seen recently. A lot of the recent research out of GFDL is about relative SSTs and the Atlantic Tripole. When you have warm over cold over warm, it causes the the subtropical ridge to set up farther north and shear decreases across the Tropical Atlantic.

Little swirl off of Daytona has been given a lemon by the NHC.

Also, global models are developing a tropical low in the SW Carribean over the weekend.

Yeah, that thing would actually have a chance if it stayed over water for more than another 12 hours.

The SW Caribbean low looks more like a rain maker for Cuba/Jamaica/Hispaniola than anything else. It's modeled very broad and diffuse with no central convection. It looks more like a monsoon depression than a fully tropical system.

the euro brings the carribean wave to about cuba and it just rains its self out

Yep. It really is modeled like a monsoon depression. That's exactly what they do in the South China Sea or Bay of Bengal.

Of possible interest, TAFB is now analyzing the extreme EPAC/Western Caribbean as a monsoon trough.

Latest discussion from NHC on the orange warning south of DR.

....SPECIAL FEATURE...

A BROAD AREA OF LOW PRESSURE ROUGHLY CENTERED 100 NM S OF

JAMAICA WITH A SURFACE TROUGH EXTENDING S TO THE PANAMA CANAL

REMAINS EMBEDDED WITHIN A BROAD AREA OF DEEP LAYER MOISTURE AS

INDICATED BY THE TOTAL PRECIPITABLE WATER. SCATTERED/HEAVY

SHOWERS WITH ISOLATED THUNDERSTORMS ARE E OF THE LOW CENTER

WITHIN 120/150 NM OF LINE FROM HAITI NEAR 20N72W TO 10N77W AND

SCATTERED SHOWERS COVERING A BROADER AREA N OF 17N TO ACROSS THE

GREATER ANTILLES BETWEEN 63W-78W AND S OF 17N BETWEEN 70W-84W.

ENVIRONMENTAL CONDITIONS ARE GENERALLY CONDUCIVE FOR FURTHER

DEVELOPMENT. HEAVY RAINS COULD CAUSE FLASH FLOODING AND MUD

SLIDES OVER PORTIONS OF HAITI...THE DOMINICAN REPUBLIC...

JAMAICA...AND EXTREME SOUTHEASTERN CUBA OVER THE NEXT DAY OR TWO

AS THE LOW REMAINS NEARLY STATIONARY OVER THE WEST-CENTRAL

CARIBBEAN SEA. THERE IS A MEDIUM CHANCE OF TROPICAL CYCLONE

FORMATION DURING THE NEXT 48 HOURS.

  • 3 weeks later...

the remnants of it could get swept up on a cold front though possbly?

The best chance would be remnant moisture rounding the subtropical ridge, riding up the Rockies, then getting entrained into a front... but my crystal ball doesn't go out that far :)

baroclinic_instability has been hyping the Para NAM over on the main board, so I'm curious to see how this unfolds.

The Para NAM at 0z last night (07/05 00z) had a much weaker surface reflection than the op NAM at hr 84

(Note this is probably a time-sensitive link...you can access the Para NAM here: http://www.emc.ncep....ll/nampll_nmmb/ )

Edit: no longer a time sensitive link, I saved the image now
