Re: ATL: IRENE - Tropical Storm - Discussion
if i caught wxman57 correctly, the hebert box does not predict whether the storm will hit Fl, its only looking back, you see the correlation?

It's always fascinating to see what people view as conservative when it comes to forecasting hurricane intensity. One group believes conservative is downplaying the intensity and opting to forecast the low-end of the possibilities. The other group believes conservative is forecasting the worst case scenario if it is somewhat likely to occur. This group believes that conservatism is gained by alerting the public that there is a somewhat reasonable chance of a life and death storm affecting them soon. The NHC has historically been in group one, believing it's in the publics interest to opt for the low-end of the possibilities when there is uncertainty. I'm in group two but it's a debate as to which is the best approach to conservatism.

This morning, it didn't even look that good. And throughout the day, Irene got her act together, tightened, and this is what we have now. Conditions are almost perfect for RI with Irene. I wouldn't be surprised if we have a hurricane before tomorrow is over.
I like your way of thinking!! You got balls and I am with ya

It's not a "prediction" tool but does provide a lot of insight for storms like this on similar tracks. It's worth your time to research it, etc.

Correct. Most storms that hit Florida go through the box, but many storms that go through the box do not hit Florida.

Wow convection is really blowing up now isn't it.
Going to be a big storm and possible hurricane when all is said and and done.
Looks like an anticyclone in the upper layers of the atmosphere is building on top as you can see the symmetric presentation of Irene and fanning cloud tops in all quadrants.
Wouldn't surprise me if she becomes a hurricane quicker than the NHC intensity forecasts calls for.

If the system ends up tucking under that convection then yeah it could well strengthen quicker then expected.
I'd have thought the chances of it being a hurricane before Hispaniola have really shot up in the alst 12hrs, esp given its already at 45kts.

Seeing how you are so far inland that you would NEVER experience the affects of a hurricane FIRST HAND, I guess you would...but for those of us who live on the coast, this isn't A JOKE to us, so I will kindly ask you to think about WHAT YOU POST BEFORE YOU POST IT! A major hurricane IS NEVER SOMETHING TO TAKE LIGHTLY!! So instead of making jokes, why don't you think about the 1000's of people this storm will affect?!?!?!

If it tucks under that convection and it maintains overnight we could be pushing cane by 5pm tomorrow at the rate its organizing.

Lets hope it misses Haiti, they don't need a minimal hurricane coming down at them after the rains from Emily and the general problems of the country.
PS, GFS focuses in on the stronger convection further north, setting up at 16N by 06z, sounds reasonable, sadly that does mean the GFS track is probably quite close to the mark as well...

it definately looks like it and it has plenty of time because of the rapid development into a storm

Re: ATL: IRENE - Tropical Storm - Discussion
What is interesting...and this begins to highlight just how uncertain the intensity forecast is....as of 2pm Monday, the official forecast is for a 75mph Cat 1, but the probability of it being a hurricane at 2pm Monday is listed as 36%.
Due to possible land interactions, in 120 hours, there is a 16% chance Irene will have dissipated, or if she avoids as much land, there is a 17% chance she will be a hurricane.
The trend of these probabilties over future advisories will be telling.

yeah I have been thinking about that possibility today. especially if the center reforms under the convection. then a wnw track would essentially take down the spine on hispaniola. but if it does strengthen to a hurricane prior to hispaniola a track just north of it is possible.. not likely at this point but still leaving the option open
