Danny and #6 Maps and MR discussion ...

#1 Postby Stormsfury » Sun Jul 20, 2003 11:44 am

Tropical Storm Danny is losing its top so to speak ... though, it's expected to loop and re-enter warmer waters in 72-96 hours, there will likely not be much left to him and will likely be a remnant low .. A couple of things also to note: The LLC is still fairly well-organized even though basically the top was chopped off ... the SHIPS model initialized the water temperatures down the road too cold by about 3ºC (the water temperatures along the NHC's forecast track is running 78ºF, not 72ºF)
Image
Tropical Depression #6 environment still remains favorable for continued development, however, with 3 limiting factors in the short term ... that are 1) Somewhat limited moisture 2) rapid movement to the W 3) poorly defined LLC ...
Notice the general spread of the projected tracks of #6 in the future ... ranging from west to an almost NW movement at the end of the period noted by the EGRR ... IMO, the northerly turn if there even is one, will be greatly delayed because of 1) small size of the system and the trough may have hardly any effect on it 2) delayed development ... the longer the delay in development of #6 means the longer that westerly course will continue. Also not to mention, the very fast westerly motion right now ...
3) I hate to use the words "climatologically speaking once again" with 2003, but July favors a more westerly track and if #6 hasn't established itself before entering the Eastern Caribbean ... development may further be delayed in the TZOD ("Tropical Zone of Death") ... even further down the road, #6's rapid motion may actually cause it to outrace its own favorable environment ... just food for thought ...
Now on the flip side, with Tropical Depression #6's small size, and if it really begins to gel or get its act together beforehand ... #6 could really develop rapidly (a snowballing effect) considering the fact that its under a low shear environment and progressively warmer waters (SST's warm enough and only get warmer ahead) ... again, the relative small size may not be enough for the trough later in the period to influence it as strongly as progged by some of the models ...

Sorry about that...redid the maps with the model notations in there ... the EGRR is the model which has #6 going over Puerto Rico...

Ok SF I still may have to watch this one closely because it may intensifie rapidly because of the small size of system.

Stormsfury - you have had the best explanation I have seen on TD6 - thanks for the input and analysis. Alot of factors have to come together for TD6 . Another long week of watching and waiting. Just personally wanted to say thanks.

Thanks, Ticka ... amazing what some a day off from work will allow me to do watching and analyzing ... (not to mention, a killer headache ... the 110 plus hours worked in the last two weeks have caught up with me)...

Hmmmm...the UKMET takes it to South Georgia, potentially moving up the EC...would that be a concern at this point?

I consider the UKMET an outlier at this point. It hasn't had a very good record so far this year but it usually handles the more northly systems a lot better than those in the deep tropics.
