More on TD#2
09:58 AM EDT - 12 July 2001

Tropical Depression #2 is looking a litte different this morning, a little more concentrated and more tropical looking. I expect to see Barry today.

For it's future, it now appears as if it will head to the Eastern Leeward islands an a minor system. Many models have it entering and staying in the Caribbean. Climatology isn't favorible for it, and if it does creep north it'll have to deal with the mountains of Hispaniola.

It won't get much chance to strengthen over that Island. There is enough to suggest it could reach minor hurricane strength, so folks will need to watch.

Persistence again will be paramount. Beyond that, it still could effect Florida in some way next week if the stalled out front does not itself. But if it does go through the caribbean and Hispaniola it won't have enough to recover. In any case, the Caribbean needs to watch this one very closely for right now, and we may later depending on what path this thing takes. It probably won't touch us at all, but the chance is still there so I mention it.

TD#2! Barry later?


What about the models? The GFDL continues to want to toss this system in the trash, but moves it slowly toward the Caribbean. The MRF keeps it in the Caribbean and mostly south of the islands. The others all do various tricks with it, but climatology is a major factor in that. This is an early cape verde style system, and it has a lot going against it.

Watch!

Well not much will change at all on the 11 AM update. Convection is there but it just isn't the most organized system. Still thinking it may become better organized after it passes 50w. I'am not expecting an change in update in half hour.

the depression has lived all of 12 hours now. it has stayed on marginal ssts through the night, but they will pick up ahead.. the system has sped up to the west, lost its convection some, so the low level flow is steering it more. the further south the storm remains, the more interesting it will probably be... assuming it doesnt hit a patch of shear and outrun its convection, as lots of early cape verdes do. dont be surprised to see tropical storm watches in another 24 hours, if two doesnt break up.
scott pointed out the convection over ne nicaragua/e honduras.. worthy of mention for its persistence, born from a disturbance north of panama yesterday. it broke from the itcz, which merits its mention... should emerge into the nw caribbean later today. in about 48 hours the dying front will be along the ne gulf coast and north of the bahamas.. so there will be lots to monitor into the weekend.

TROPICAL DEPRESSION TWO DISCUSSION NUMBER 3
NATIONAL WEATHER SERVICE MIAMI FL
11 AM EDT THU JUL 12 2001

SATELLITE IMAGES SUGGEST THAT THE TROPICAL DEPRESSION CONSISTS OF A
SMALL BUT ROUND AREA OF DEEP CONVECTION WITHOUT BANDING FEATURES.
IT IS VERY DIFFICULT TO LOCATE THE LOW-LEVEL CENTER BUT USING
CONTINUITY...BUT IT IS ESTIMATED THAT IT IS LOCATED UNDER THE
CONVECTION. THE OUTFLOW IS FAIR...MOSTLY ON THE WESTERN SEMICIRCLE.
UPPER-LEVEL WINDS APPEAR TO BE FAVORABLE FOR THIS SYSTEM TO
STRENGTHEN. HOWEVER...BASED ON THE POORLY-DEFINED SATELLITE
PRESENTATION...COMBINED WITH THE FACT THAT MOST OF THE NUMERICAL
GUIDANCE DOES NOT SUGGEST INTENSIFICATION...THE OFFICIAL INTENSITY
FORECAST SHOWS ONLY SLIGHT STRENGTHENING. IT IS POSSIBLE THAT THE
DEPRESSION WILL WEAKEN TO A TROUGH OR A LOW PRESSURE DURING THE NEXT
24 HOURS. IN FACT...THE GFDL MODEL DISSIPATES THE SYSTEM RAPIDLY.

THE DEPRESSION IS MOVING TOWARD THE WEST-NORTHWEST AT 17 KNOTS ALONG
THE PERIPHERY OF A STRONG SUBTROPICAL RIDGE WHICH IS FORECAST TO
EXTEND WESTWARD. IF THE DEPRESSION SURVIVES...IT SHOULD CONTINUE ON
THE SAME GENERAL TRACK THROUGHOUT THE FORECAST PERIOD WITH SOME
DECREASE IN FORWARD SPEED. IF IT WEAKENS....IT COULD TAKE A MORE
WESTERLY TRACK.


This one may not make it!!

Thats a big question right now. Theres a chance it will but theres also a chance it won't. Never the less it needs to be watched, not writing this system off any time soon. 11 AM update still holding its same strength at 30 mph, with foward speed increasing a bit up to WNW at 20 mph so its moving. Other good points where brought up in the posts ubove about the western Caribbean and norhtern Gulf. So lots to watch. I was a bit concerned with the north gulf earlier in the week when I found out a front was coming all the to the Gulf Coast. But shear is is strong in both areas. So lots to watch this weekend.
