The only thing I worry about is somehow ridging building in above this Invest and sending it to the east coast again.......I know it's long term, but the Euro is pretty scary on strength... Let's just hope and pray that the models continue to keep it out to sea.
The good news is that it's already up to 30% for development, and developing this far out, should result in a recurve situation.....
The only time I would start worrying is if we begin to see a more westward trend with the models....Until then, no worries.....

Yeah, as long as by 24 hours we have a closed system since that is what the Euro shows in its forecast for recurvature, No problem If its weaker, it goes further westbound. NHC is 30% within 48h not 24.

Adoquín wrote:of the three the first two affected Puerto Rico, one the Cat 3 going straight through and the third was far away, strong and to the south, enough to cringe. I agree that is too little data to predict anything.
However, I note that being so down south it may take it longer to detatch from the ITZ, which would not be good, The high has tended to be strong. Do for now based on Luis data itcis rational to err on the side of stronger as opposed to lower values. Other parameters hav to be examined. How is Mr. Sal doing? how fast is it moving west? how strong can it get so low based on the precedents mentioned while it remains so low? big questions and depending on the answer another monster?
Puerto Rico hurricanr history has several periods of multiple strikes in a single year by significant hurricanes, mostly on a e or se to wnw direction. It generally happens at least once every century Seversl of those hurricanes ended somewhere in the East Coast , from the. Keys up.
It will be very important to see if by being at low latitude,it avoids any weakness that may be in the Atlantic. The position where it is now reminds me of Georges. But of course,there is plenty of time to watch it to see how it will track.

Re: ATL: INVEST 92L - Models
Luis, Everyone is either dealing with Irene or they are catching up on sleep after a week of tracking here. Got to rest up now because the trend of the models looks like we are going to have something else to track in the coming days.

Re: ATL: INVEST 92L - Discussion
Low latitude, slow westward track = possible trouble for the islands! Let's see what it does.

Re: ATL: INVEST 92L - Models
After watching the models take Irene( she put a beating on me in eastern NC) from a eastern GOM threat to almost a recurve I am skeptical of any long range model right. However if this one develops early then the recurve or the apparent recurve seems likely.

Re: ATL: INVEST 92L - Models
[quote="SFLcane"]Could be luis...One thing is for sure models for the time being are faily aggresive in terms of development.
Experimnetal FIM is also developing it and turns northward pretty quickly.
How has the FIM done in comparison of performance with the other models?

The ridge would have to get stronger and 92L would have to develop slowly for this not to be a fish. Still to early to say..

Re: ATL: INVEST 92L - Models
Some westward trend from the early recurvers (they still look to recurve east of CONUS based on latest runs)
06 GFS recurves near Bermuda
00 FIM looks to threaten Bermuda.

TRMM showing a lot of small hot towers. This could be a strong system.
Waiting to get AMSU soundings to see if a warm core is developing.

Re: ATL: INVEST 92L - Discussion
THIS is the storm that has me concerned. It is in the traditional Cape Verde slot and if the Bermuda high builds back in there's nothing but warm water and real estate for this sucker to traverse across the Atlantic. Makes me wonder if those who said this might be another Greek alphabet year are on to something.
