Bryan63 Posted October 7 Share Posted October 7 Looks like this is tracking towards landfall as the tide is coming in but luckily not at high tide which isn't until about 6am Thursday. Link to comment Share on other sites More sharing options...

RU848789 Posted October 7 Share Posted October 7 Question for folks/mets who know the model data initialization process. The 18Z model runs (at least GFS, NAM and ICON), which I always thought initialized at 18Z (or 2 pm EDT now) with data from the 18Z time point or at least not much earlier than that, all show the t=0 point with Milton at about 970-980 mbar, when Milton had a pressure of 925 mbar at 12:00 pm EDT today...and it was even as low as 945 mbar at 8 am EDT. Am I missing something? 2 Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted October 7 Share Posted October 7 Unreal. I can't believe what went on today...colleague of mine made the astute observation using an altimetry of ocean currents that Milton may have availed itself of Helene's upwelling by feasting on very warm waters that wrapped around the Yucatan. Final Call tomorrow. 1 Link to comment Share on other sites More sharing options...

Eduardo Posted October 7 Share Posted October 7 2 minutes ago, MUWX said: Levi pointing out that recon confirms an ERC is making an attempt at getting underway “[M]aking an attempt” is accurate though, IIRC, we have seen some storms during the past few seasons that featured double- and even triple-maxima without completing a full ERC and weakening accordingly. Maybe someone else can chime in and double-check my memory though. Either way, ERC’s remain incredibly hard to predict. 1 Link to comment Share on other sites More sharing options...

NeonPeon Posted October 7 Share Posted October 7 20 minutes ago, DDweatherman said: There’s reason to believe it was even lower at peak given the recon left before the “best” satellite images. we’re blessed here to have them in at the peak times. Not to be picky, but I think this looked better an hour or so ago. At the end of the day, they aren't going out to collect trivia for us. 1 1 Link to comment Share on other sites More sharing options...

WishingForWarmWeather Posted October 7 Share Posted October 7 I have to believe the little oscillations I’m seeing in some of these loops is the precursor to an ERC. Edit to add: who knows at this point. I honestly thought the radar out of Mexico earlier showed the beginning of the band that would start it but that solid inner eye has really held on. I just remember Rita? Or Wilma? One of them. Started oscillating around before the ERC. 2 Link to comment Share on other sites More sharing options...
TPAwx Posted October 7 Share Posted October 7 HAFS-B landfalls early Thursday AM at Ft DeSoto/St Pete. 963 Heading out to evacuate inland. Really appreciate the pros and advanced hobbyists that have and are providing analysis and explanations in a digestible and fact-based way. It's been really helpful to understand and plan for Milton. Best of luck to all in the path, get out of the way and be safe. 19 Link to comment Share on other sites More sharing options...

WxSynopsisDavid Posted October 7 Share Posted October 7 2 minutes ago, dan11295 said: Milton is already basically very close to maximum potential intensity, really can't get much stronger. Yes it can, pressure can easily drop into the 880’s now. Don’t think 190-200mph winds is out of the question because how healthy the CDO is and the fact the eye is only 2 to 4nm wide points to pressure continuing to tank. Until we see a double wind maxima which is the beginning of an ERC, Milton will continue to intensify. 3 1 1 Link to comment Share on other sites More sharing options...
wxeyeNH Posted October 7 Share Posted October 7 I'm trying to visualize what it would look like meteorologically if you were in the middle of a 4nm eye? Wind blowing 175 miles an hour in opposite directions only a couple miles to either side of you. It wouldn't even look like CuB all around you as the towers would be too close. Just a pinhole of clear skies overhead with darkness and noise all around? I assume such a small eye has never been witnessed. There are pictures within Michael's eye near Mexico Beach but the eye was much bigger. 4nm is amazingly small! 11 1 Link to comment Share on other sites More sharing options...
Moderately Unstable Posted October 7 Share Posted October 7 43 minutes ago, cardinalland said: well first atlantic storm in the 800s since i started tracking. Few bites from dropsonde(s) (ne eyewall and eye). (1) They dropped in ne eyewall, and the sonde rotated halfway around the eye. (2) Still dumping mass at the upper levels, cloud tops are still cooling still deepening, (3) mean LL wind in bottom 150 meters of eyewall is 200 mph. You can expect some of that is mixing to surface with this storm structure. Thus, I would presume they go with 190 mph on an update. You may have noticed that surface wind speeds shown on nhc products tend to be a blend of the lowest 150 meters, not specifically the surface wind speed. 37 minutes ago, RU848789 said: I assume this is pretty official. 897 mbar. https://x.com/WxTca/status/1843424669959176251 Not really official. Official would be Levi, Tomer, NHC staff, hurricane hunter staff, other experts on hurricanes. Not a diss - but since this forum is likely being viewed by thousands right now (not just members), some of whom are using this for decision making...be careful about official source citing. 37 minutes ago, Eduardo said: “[M]aking an attempt” is accurate though, IIRC, we have seen some storms during the past few seasons that featured double- and even triple-maxima without completing a full ERC and weakening accordingly. Maybe someone else can chime in and double-check my memory though. Either way, ERC’s remain incredibly hard to predict. This is a small storm at near the maximum possible pressure attainable. Modeling, experts, and forum Mets have all generally had consensus that we will see an ERC. One will occur (or more). In sum, once we reach the maximum possible intensity for a given eyewall and the inner eyewall contracts to maximum possible extent, the outer bands strengthen and close. The closure initiates an ERC. Given the environment and near-record pressure, forecasting an ERC is not a reach (it frankly doesn't require a lot of expertise). When this occurs, conservation of angular momentum applies. Storm wind radii increase, wind speed decreases, angular momentum remains conserved-(ish with some caveats). 18 minutes ago, WishingForWarmWeather said: I have to believe the little oscillations I’m seeing in some of these loops is the precursor to an ERC.

I just remember Rita? Or Wilma? One of them. Started oscillating around before the ERC. ERCs take time. Many hours. So as Levi said in a post quoted a bit ago, even if there are minor hints of one, it isn't there yet. One last thought. "Historic" is a word I think that is overused in meteorology - this forum is guilty of it, I am guilty of it. But, I think where this is right now you have to just appreciate that this is history. Right now. You're watching it. It will be in tropical meteorology class references in the future. 8 3 16 Link to comment Share on other sites More sharing options...

dan11295 Posted October 7 Share Posted October 7 18Z GFS shifted S at landfall. Definitely seeing positive trend for now as far as Tamp Bay. Verbatim its still very bad for Tampa but its the trend I am looking at here. 4 Link to comment Share on other sites More sharing options...
