Now lets see if the 12z Euro stays consistent with last night's run.


Right. The strange thing is that with < 5 days before NHC track landfall, we have a legitimate hurricane threat that might not be anything of substance at least until the Bahamas. It's probably going to pulse up and down for the next 48-60 hours (or longer) as per the GFS anyway. And you have possibilities from an open wave with some squally weather to a deepening Category 1 - and we won't know probably until within 30 hours of potential FL landfall for sure. Some people might just stall out on making decisions, so I would bet that NHC probably continues to keep it classified as at least TD Erika (were it to degenerate) throughout the forecast period just to keep it fresh in people's minds.


Agree with everything you just said except that I'm thinking that the range could be even broader - from a wave to a major hurricane. It will have to contend with poor conditions today, however if we see significant renewed convective bursting as we had last night, than I"m thinking that we'll actually start to see Erika begin to better organize at the point of hitting those warmer SST's just north of P.R. I'm not seeing that cut off low progged to be over E. Cuba, as continuing to be as a destructive cause for vertical shear as the discussion indicated- that is, assuming that today doesn't take too much a toll on its present overall structure.

Erika has hazy convection. I've noticed over the years that many strong hurricanes showed hazy convection when they were forming. It might not mean anything in this case.

The surface spiral is now exposed just NW of the convection.

Erika is truly being tested. If it can survive the shear between now and reaching just north of Puerto Rico, then I'm nearly convinced that she'll survive and then begin to strengthen. Very key will be how much convection will she continue to pop, thus at least helping to stave off from getting entirely decoupled and the LLC from completely running out from under the mid level circulation. That and whether or not the projected decrease in forward speed has or will soon occur.

The center is always a lot easier to find when it isn't covered by convection. As expected, Erika is having trouble today. I suspect it won't recover well until it passes Puerto Rico tomorrow and moves toward the Bahamas.

Narrow the expected winds for Florida range yet?

If it keeps heading westward and over the larger islands, it might not survive at all (just my opinion)...

Right now, it's hard to define a MLC - outflow is also hard to discern...

P.S. Our low-level flow today is from S to N - usually when it's that way, we aren't concerned with systems to our east...

agree, very hard to find a MLC even with the low level center exposed partially. Very ragged structure and a trip over Hisp would shred the LLC.....wow lots of "IFs" with this storm...

Yup...kind of tells me that this will stay on life support until its north of PR. HWRF and GFDL are too strong much to quickly. i.e. too far EAST in the end...JMO the DOC is coming out now, check it out over on the model page.

"If" this doesn't survive, it's going to makes lots of Florida residents very very happy. I can imagine the unease they were feeling when they heard about the news of the storm heading their direction...... Crossing my fingers this will get shredded....

Since the models are pretty tightly clustered regarding the track of the storm, is it safe to assume the OBX can sit this one out?

Thanks

Models are only fairly well clustered over the next 3-4 days. You're not out of the woods yet up there.

Hopefully, no one gets this. As it looks now, your gut feeling...we (Houston) are almost assuredly ok...:)?

I don't need any gut feelings as far as Houston - Jet core from SW-NE across the Gulf won't let it come this way. Euro is indicating a hurricane passing east of Florida and heading for the Carolinas, though.

Thank you all your predictions.
But for us in Florida.. This is a wait and see and everyone is skeptical. Yes, the storm is very weak right now. But even if it does die.. Could it redevelop as the thunderstorms move in the Bahamas?
I know some on here are saying that this will not hit us because we are used to being in the cone but nothing happens.. Please be careful what you say because eventually our luck will run out and second of all.. People here are confused in FL and we dont want people to think its not coming and then this weekend we are told to prepare. Please wait and see! After 10 years of no hurricane.. Fl citizens are not really taking the potential threat seriously.
This storm is very interesting. Thank You -
