Still a ways off - so no need from drama at this time - but she might impact KSC operations next week...

The name? No - but will be in the next 24 hours (if not already, looking great on sat.)

It is now...farther away from the coast than I thought, too.

Rob, Any comments on the NHC's near total inability to predict where a storm will be this year more than 24hrs out? and sometimes not even that far(Fay and Gustav both).  This year seems to be the year for erratic storms.

Well, predictions are just that. Living in Florida we know not to look at the line on the map but rather the entire threat cone. If you go by that, the location of the storms (Fay and Gustav) have fallen in that cone. As for timing, one can't even predict with absolute certainty how long their drive to work will take.  Sometimes you're early. Sometimes you're late. Storms are the same way.The timeline for storms is just an educated guess based on what the weather will probably be like when the storm reaches a certain location and what effects another weather system will probably have on the storm in question.

It's been an "off-nominal" year to slip in a NASA term ;) Look at Fay's final path - it meandered every which way. The steering currents aloft just aren't very organized, which makes prediction all the more difficult.

To put it in simpler terms - when I have a line of strong storms to my west moving east at 45mph, and I know the environment overhead supports them remaining strong, it's VERY easy for me to tell that you'll get wet at 1:45pm. If it's a typical summer afternoon, where storms pop-up/die at will and move 5-10mph, I have no idea whether or not you'll get wet at 1:45pm...

Well, the NHC does have 100% success with providing insurance companies the "rationale" to drive up home owners insurance unnecessarily.

a new path direction with forecast at hurricane strength pretty near KSC.  I really hope this doesn't come to pass... the lost contingency days are really starting to put a strain on STS-125 and now STS-126.  Not to mention a couple of other launches from CCAFS.

Hanna turned out notably weaker than expected when recon arrived today, I wouldn't push back launch dates based on her yet ;)

Forecasts look a little bit better today, not showing Hannah as a possible Cat1 near KSC anymore.


Upd: Seems to get stronger and closer to KSC.

The system near Africa now has a high probability of becoming a tropical system:

Note:  This would be considered a Cape Verde Hurricane, which are EXTREMELY DANGEROUS

Hurricane Hanna is now starting to affect rollout plans for Atlantis; it will be interesting to see how close she gets to KSC around Thursday per the current track predicts, and what her effects on KSC will be.

I can't see a rollout happening.

It could strengthen and change track very easily.

Here's something to consider  (Its called Invest 99L for the short term via NHC.) The Strongest storms form from Cape Verde storms, but THE strongest storm that ever formed in the Atlantic formed from a Cold Front. So, yea, Cape Verde Hurricanes are extremely dangerous. Good news is, this one doesn't look to go anywere near land judging by the models.

Uhh - Hanna is not that far from land, so I'd check different models ;)
