Re: ATL: INVEST 92L - Models
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.

For now, lets just keep watching it..

I agree with that. We will have to watch it, but I guess it all hinges on how strong or not the high pressure will be in the next few days in terms of track.

Re: ATL: INVEST 92L - Discussion
Future Jose. Longer it takes to develop, the more west 92L could go. If I recall, Ike formed further north of 92L and it went westward despite being a hurricane. Ike was tagged as Invest 97L.

If this develops at 8 north it might have a hardere time feeling weakness. Will do a stat analysis of east Atlantic storms that formed below ten later tonight or tomorrow.

It appears that the ridge may be relativly strong if the NAO forecast is right about being neutral to slightly positive.

Disclaimer: 50% of the time I have no clue of what I am talking about. Chances are I am taking a less than educated guess that sounds good because 10 years ago I stole Mike Watkins book 'The Hurricane and its Impact'. For official information please direct yourself to the NHC and their cadre of weather geniuses.

MIMIC-TPW shows good convergence and it is low.

I like JB, he's a kick to watch and listen to, but the problem regarding his 92L forecast is that he never looks at what the models are forecasting, he just mentions right out of the blue that it will threaten the east coast....

Re: ATL: INVEST 92L - Discussion
These statistics may not be of any real relevance, but they might be worth noting.
Since 1968 (I wanted to use data from the satellite era), ten tropical storms and hurricanes have formed from depressions first classified south of 10N and east of 35W.
Of these, six grew into hurricanes. None of the ones that did not become hurricanes significantly affected land.
The three hurricanes in this example are Bertha (1996), Georges (1998) and Ivan (2004).
Therefore, it is really not possible to say whether a storm that forms far to the south has a greater chance of affecting land, as there are too few storms that formed in that place.

will this suffer the same fate as 90L? are the conditions ahead still unfavorable?

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.

Re: ATL: INVEST 92L - Discussion
Hi S2k members, I analyzed September via my "natural disaster date" method and wanted to share that the next potential hurricane risk dates are September 3rd-6th with the 3rd,4th and 6th being most notable. It will be interesting to see if they coincide with anything this invest 92L will do if it forms by then. I figured I could provide this info as a backup to any models that foresee a landfall during these dates.
Looking at the timing, it may be something for the Leewards/PR if it were to form into Jose huh?
It's far out on a limb but I predict a possible impact coming from a storm down the road between 9/3 and 9/6 in the eastern Caribbean Islands as hurricane, perhaps strong hurricane on 9/4. This may come from 92L or whatever follows it. This is just my opinion, so in case this invest does develop...you know the drill.....listen to NHC. Just wanted to share this with all of you. I hope it helps in some way.
