The system in the western Caribbean (97L) is needing slightly deeper convection, but otherwise seems on its way to developing. The current idea is that it will remain stationary or move very slowly at least in the initial run. It may go over Central America or stay more offshore potentially affecting the Yucatan or perhaps the Southeast. This is where you can suggest what may happen, make a guess (with some reason behind it) or otherwise discuss the models and possibilities with the system. update: at 11 AM on the 4th, it was upgraded to a Tropical Depression Update#2: at 3PM Recon showed what is very likely Ida, along with NRL updates |
||||||||
|
|
|||||||
Looking at the satellite presentation this AM, I would not be surprised if this afternoon's recon finds a strong TD or minimal TS as long as the convection remains as strong as it seems to be. Until something definitive is determined, the model runs will be pretty unreliable. Something to watch, for sure. |
||||||||
|
|
|||||||
Long range models for TD#11 take it east or over the Yucatan into the Southwest Gulf. Aka GFS. After that it may meander in the Gulf a bit too, great uncertainty in the forecast with a slow moving system, assuming it survives the cross over Nicaragua and Honduras. |
||||||||
|
|
|||||||
One question, then a semi-educated guess. I'm sure that SST's where TD #11 is currently located are supportive of development, but what about the SW GOM? Since we are looking at a system of questionable strength and organization when and if it re-emerges (early next week), there would likely be a digging trof that would shear and shred the circulation. After that, some areas would get bonus rainfall with the front that absorbs the remnants. That being said, Tallahassee's last hurricane hit in November, (1985 - Kate), and tore this (inland) area up. Lots of big trees and branches in the State Capital... |
||||||||
|
|
|||||||
Well, recon found a strong TS. Ida it is! |
||||||||
|
|
|||||||
The 18Z GFDL. is moving closer to Cuba in the longer term, which is more usual for these type of storms, either they crash into Central America and die, or skirt along the coast and make it east of the Yucatan, a bit weaker. If it stays on the eastern edge of Honduras then it will pass along more flat terrain, west into Honduras gets into some fairly rugged mountains, which would tear up the storm. The GFDL here somehow keeps it offshore, and s a bit nuts with intensity (on the high side), so I'm not sure I'd take much stock on this run. |
||||||||
|
|
|||||||
GFDL always does that it seems with the STR of a storm why no idea but it seems to over do there ppower. |
||||||||
|
|
|||||||
My forecast is that this site gets a whole lot more hits by the time Sunday comes round |
||||||||
|
|
|||||||
I think the GFDL intensity is very believable if the models premise that it remains over water the entire time plays out. That said, its seems unlikely that it wont landfall to some degree in Nicaragua . I dont think it will be as much as forecast though |
||||||||
|
|
|||||||
Quote: Hey, now there's a forecast that sounds more like a promise! Yes, it should be a very interesting weekend should 'Ida' decide to not trek inland and fizzle out, which seems to be less likely with each model run and official advisory issued. .. |
||||||||
|
|
|||||||
seems like that is what people want more then anything |
||||||||
|
|
|||||||
It is premature to think that Ida will be tropical and deep enough vertically to survive into what currently is a very hostile upper environment other than immediately over the storm. That said, there has been considerable discussion as to the evolution of the old dying frontal remains in the extreme SW Gulf of Mexico and Bay of Campeche into becoming a subtropical or hybrid system later this week. It is highly doubtful a pure tropical system will evolve, however a subtropical system is more likely to be the result given the environment later in the week and where upper level features are progged to be. In that event, it is possible an approach to a US landfall along the Gulf of Mexico is possible. |
||||||||

|||||||
Not sure which model they use to develop this forecast, but play out the wave height loop. Projecting 15' waves in the Central Gulf at about Tampa latitude mid next week. Wind vectors indicate a center of circulation driving the waves. I watch this site for deciding whether to fish the gulf or not and thought it would be interesting. On their hurricane page, the indicate that they use the GFDL wind table so that may be the underlying model for this projection. http://www.swellinfo.com/surf-forecast/clearwater-florida.html TD |

|||||||
No wishcasting here, just posting up some interesting info. Lived in Fl all my life and know the unpredictability of these storms all too well. My post said Central GOM at about Tampa lattitude, not a Tampa landfall. TD |
||||||||
|
|
|||||||
Ida continues to need to be watched even up here, although conditions further north are much more hostile, it has a window to get stronger once it is back over water before hitting poorer conditions. It could bring more rainfall to the central or more likely eastern Gulf somewhere. If it does make it to the Gulf, conditions will likely be very hostile for the system which may split it up vertically like so many other storms this season. Ida is worth watching for this reason. |
||||||||
|
|
|||||||
Definitely keeping an eye on Ida. The NHC discussion at 4:00 PM EST seems to be hedging a bit that Ida may dissipate over Central America, particularly if the circulation remains over land rather than moving more Northward back over open water. The time over land and the high shear environment just to the storm's north could well be its death. |
||||||||
|
|
|||||||
If Ida restrengthens some and makes it into the Gulf (Around Monday) and converts over to an Extratropical system, it still may be somewhat nasty and cause some coastal Flooding along the gulf. Ie, a pretty nasty day along the west coast of Florida. How much it gets torn up depends on the Cold front approaching next week. If the front slows down or stalls out before that, it would give Ida more time to maintain itself. It's just if it's a tropical storm, or extra/sub tropical at the time. The appearance of Ida Tues-Wed will probably be elongated southwest to northwest with it likely being fairly rainy cloudy and somewhat windy in Florida then. Nothing too dangerous except maybe some light coastal flooding. The center of Ida could still stall and get blown apart or away either, so that's why this statement is in the lounge. |

Quote: Hi! I'm writing from Italy. In 10 days time I'll be in Miami: do I have to worry about this friendly Ida visiting Miami coast? What do you think? Will it be a danger over there, is it suggestable to avoid coming? Thanks for reading. Sofia |
||||||||

|||||||
10 days from now, it seems likely that Ida will be ancient history. No need to change your trip. When all is said and done, for Florida, I think Ida will end up being a breezy rainmaker. At the worst, some broken tree limbs and power outages if it even holds together enough to strike land. |
||||||||
|
|
|||||||
Tropical or extratropical, it has the potential of being dangerous and damaging. Evokes memories of the "no name" storm several years ago. It caused a lot of damage from wind and storm surge on the Florida West coast. March, 1993 |
||||||||
|
|
|||||||
I don't think Ida is an apt comparison to the storm of the century. That one was a completely different bird with the mass of extreme cold air and the jet stream behind it. It is the only time I can remember being in the 70's in the morning and seeing snow in the afternoon without getting on a plane. Not to mention it happened in Florida. Assuming Ida continues on to hit the coast, unless the factors push it back into the Northern Caribbean for a few days after it emerges into the Gulf(a scenario with slight possibility but not one of the likely ones), I just can not see Ida becoming a dangerous storm to Florida. Ida is going to have to camp out near Cuba to really gain some strength. I am not saying it is not possible; but I would not be changing any plans to come to Florida because of Ida. |
||||||||
|
|
|||||||
I was just thinking that similar strength, on shore winds in this part of Florida are not good no matter what type of storm is causing it. Ida or its remains could be very damaging along the Gulf coast of Florida if it maintains any significant strength. |
||||||||
|
|
|||||||
Thanks a lot for answering. We'll wait and see. |

I am getting flashbacks to Wilma from 2005. She started in this general area and ended up shooting across Florida after getting caught up in a late October frontal trough. Now I know the situation is different and Wilma was a LOT stronger when it hit the Yucatan, but some parallels are showing up. I just couldn't see it going into the Gulf and moving very far west this time of the year. Looks like the intensity forecast is going to be VERY important for us here in Central Florida. |
||||||||
|
|
|||||||
looks to be going back to the NNW after a slight jog to the E |

Quote: the whole setup is way different then wilma.We are talking Nov with shear up over 20mph and now all the 18z runs are sending it right back down once it gets into the gulf and most of them are coming around to the idea of falling apart when it gets into the gulf.But this is a totally different animal then wilma by far totally different setup. If it makes it to a Med TS ill be shocked. |
||||||||
|
|
|||||||
Lamar, funny thing. I just left work and apon leaving, myself and some coworkers where discussing Ida and what was in store for us next week if it indeed Ida should affect the west coast of Florida and us in central Florida. Wilma popped up time and time again during our conversations. I know now that after reading your post that we had the same flashback that you had.............Time will tell. |
||||||||
|
|
|||||||
If it moves east into FLA, this is a typical late season storm. Thinking the same thing about Wilma, from here in Naples. Hopefully wind shear and weather patterns will keep this from landfall ANYWHERE in Gulf. Say "NO" to any special assessments for storm damage! |
||||||||
|
|
|||||||
Watching and waiting here on the so. FL gulfcoast. Looking at the imagery over the last hour looks like it's moving more northward, thinking western Cuba could see worse conditions than the Yucatan in the next couple of days. |
||||||||
|
|
|||||||
The Panhandle and western Florida looks like it will get the worst of Ida, although at the long range models suggest near Pensacola. But I think at the time Ida will look very un-tropical, so points east will get the main effect. Coastal Flooding could be nasty, especially if it decides to park out in the Gulf a bit. |
||||||||
|
|
|||||||
this is true but if you look at the last 3-4 runs of the models each time they are trending more and more north with each run so we shall see. |
||||||||
|
|
|||||||
Yeah with the trends I could see it crossing the coast near Pensacola and then re-emerging into the Gulf, still all extratropical though. It is moving further north faster than expected. |
||||||||
|
|
|||||||
I am not liking the evolution of the models. I think I am going to play it safe and do a mini-kit stock for extended power outage (12 - 24 hours). Too many trees near powerlines around me. It is just too complex of a pattern for me to have confidence that it won't be gusty and nasty where I am. What I worry about most is Ida building more strength than is currently forecast while near Cuba and then getting caught up and drawn north at a much faster pace and having more energy at landfall somewhere in the Florida Panhandle. I'm not sure that is the likely scenario. Probably what I would call the worst-case scenario and, therefore, the scenario I plan for. I would say this storm bears heavy watching for interests from New Orleans area to the SW Florida coast with primary concern being Biloxi to Tampa, especially coastal. A faster move will prevent heavy coastal flooding. But the current NHC forecast would be very rough for the Panhandle down to Tampa Bay if it happens. I still think the worst case is a hit at marginal hurricane strength. Most likely seems to be a system with medium TS force winds transitioning to extratropical. I think the interaction with the system in the Bay of Campechee is also a fly in the ointment over the next few days. This one will test the skills of the forecasters at NHC. |
||||||||
|
|
|||||||
12z model runs show more and more of a north gulf coast landfall i would look for the 5pm track to be even more north with a landfall in the panhandle.She has only a few more hours it seems before the hostile area begins id say a 50/50 shot a a cane cat 1 before dropping back down. (Post moved to the appropriate Forum.) |
||||||||
|
|
|||||||
I did not want to put this on the front page thread. So I will ask here. Can someone direct me to a link where I can find the initialization information that the 18Z GFS used for Ida? |
||||||||
|
|
|||||||
More recent wave height projection, pretty sure it is the GFDL model data used to construct this graphic http://www.swellinfo.com/surf-forecast/pensacola-florida.html TD |
||||||||
|
|
|||||||
I'm starting to think that the GFS might be pretty close to correct, even though it may be just tad high on pressure; but I don't think by too much. I really am not seeing the looping back idea. I think Ida is more likely to merge with the boundary and exit in the Atlantic into a nasty noreaster' for the northern mid-Atlantic coast. Still too soon to feel that with any confidence. |
||||||||
|
|
|||||||
Quote: It looks like my forecast verified, but that was an easy one |
||||||||
|
|
|||||||
Quote: The GFS has had a monster Nor'easter on a couple of runs that look like Ida's energy interacting with a lot of Baroclinic energy then getting stuck off the midatlantic coast due to blocking. There were projections of 4in of liquid precip in subfreezing areas which would be a WHOLE lot of snow should it verify for WV and Central PA |
||||||||
|
|
|||||||
The looping to the east and possibly down the peninsula after landfall may be interesting, the Euro is pretty crazy with that, but most of the models are suggesting it, including the NHC's forecast. |
||||||||
|
|
|||||||
Is anyone watching? The eye, while apparently doing a wobble just almost wobbled "out of" the wind field to the west. Biggest wobble Ive ever seen. The eye is in the farthest southwest section of the wind field now lopping off the northern activity. Maybe the whole track will be moved west. Or maybe this is the start of the push to the south some models (i.e. BAMS) predicted. (This watching the NOAA Eastern U.S. JSL Color Infrared Loop at 7:45 UTC) |
||||||||
|
|
|||||||
I live on the east coast of Florida and for days we've had winds gusting to 35mph coming mainly from the east. My roomate said he just read on AOL weather that these winds are coming from Ida. I find that hard to believe. Is this true? |
||||||||
|
|
|||||||
Not ida directly, it's the gradient between high pressure to the north and the low (Ida) in the Gulf. Ida itself has its own wind energy north and east of the center. It's just going to be nasty all week with the combination of the two. |
||||||||
|
|
|||||||
Been breezy here in the Tampa Bay area for several days. I'm relaxing today since Ida is staying well to the west of my area. The only thing to watch for now is high surf conditions tomorrow as the wind becomes more onshore and the approach of the cold front which could bring the threat of thunderstorms/squalls on the back side of Ida. |
||||||||
|
|
|||||||
Is there any explanation, other than "her last gasp," for the apparent convective burst ongoing? And what are the ramifications for lower Alabama? Thanks. |
||||||||
|
|
|||||||
Wanted to crow from my prediction back on Wednesday. I don't get too many of these right, and since we're looking at a diminishing threat, why not?: Since we are looking at a system of questionable strength and organization when and if it re-emerges (early next week), there would likely be a digging trof that would shear and shred the circulation. After that, some areas would get bonus rainfall with the front that absorbs the remnants. That being said, Tallahassee's last hurricane hit in November, (1985 - Kate), and tore this (inland) area up. Lots of big trees and branches in the State Capital... |
||||||||
|
|
|||||||
Anybody give any credence to Bastardi's future track, which brings Ida off the SE coast and then bombing into a several day event hybrid storm? I will give him credit for his Fri/Sat prediction for a Cat 2 for Ida. |
||||||||
|
|
|||||||
What remains of Ida is the small area of convection that now exists near the center and while it may be a hurricane briefly prior to landfall, the bulk of Ida is onshore as shear took its toll earlier today with the lone exception of that convective burst. Ida's center may in fact be tropical, but Ida's appearance on satellite is that of a subtropical cyclone as the non-tropical low to its west, incoming shortwave will begin to merge once Ida is onshore. I haven't looked at the 12Z model run but there was earlier discussion of a low "bombing" out off the coast of GA/SC as the next shortwave dives into the upper level trough just off the SE coast as flow aloft becomes NW. |
