So while there is a whole lot of hand-wringing on the low-level center reforming farther north and shifting the track farther north...in reality the system is developing as forecast and is on track to follow the forecast path along or just south of southern coast of Hispaniola.



AGREED!!!! Guidance is doing a pretty darn good job so far.

Looking good!

Seems like a convective band is trying to wrap around on the W side.

well being that the wind is shifting the NNW in Guadalupe. that would suggest the center being a little farther north.. possibly more associated with the "mlc" that is really really close the radar site.. lol

you can sorta see the center in this loop, and to me this is still moving wnw and it is still farther north from the NHC forecast track. If it keeps heading in this direction, i think it would be heading towards PR... and it does look like its getting better organized. JMHO.

Very sound reasoning. Although that doesn't explain why the NHC implied there could be a shift to the north, my guess is that they're just trying to be cautious?

Changed the period to a question mark. :wink:

If the convection can start wrapping around that center, LOOK OUT!

Evening everyone, (daughters wedding here at p'cola beach went off in spectacular fashion at 5:30 pm this afternoon) Told her she was possibly very lucky she didn't pick NEXT Saturday as the date for her wedding. I see IRene is looking good this evening, Everyone in the islands take care..and EVERYONE in the southeastern gulf and the entire peninsula of FLa..be vigilant. Thanks to all the knowledgeable mets as well as the weather enthusiasts sharing their vast experience dealing with tropical systems with all of us as we all watch, wait...and begin thinking ahead as to what exactly we need to do just in case this heads our way.

In the last animation posted, it appears that the convection is starting to wrap around the center (assuming it is where we think it is) :D

Aric, obviously we have people offering differing opinions about center placement and track. Some seem to believe that the so-called west shift in track will be more pronounced. It seems to me that any center relocation to the north will result in a right shift, if ever so slightly. What is your opinion?

Thanks for that and keep letting is know if it changes. do you have you own set up ? if so is it verified as accurate and calibrated? if not the reporting stations is what I will stick to atm and is what The NHC would go off of as being official..

MY OPINION ONLY: I think Irene will initially move along the N side of the cone and result in a Hurricane Watch for PR!
