Windspeed Posted October 7 Share Posted October 7 Keeping a close eye on these fixes as well. The TC models want Milton's eye to lose .5 to .8 degrees of latitude over the next 18 to 24 hours as it passes south of Isla Pérez. Granted, that's not much, but it could have implications downstream on the location of ENE to NE turn.Edit: The exception is the HMON, which has a direct hit and landfall on Isla Pérez.

MANDA Posted October 7 Share Posted October 7 Based on the data this evening I would not expect much if any changes with the 11:00 TPC package as far as max intensity or track. Maybe they nudge the landfall location a smidge north. Certainly the initial intensity will be UP. 1 Link to comment Share on other sites More sharing options...

Windspeed Posted October 7 Share Posted October 7 Well, that settles that...I was about 24 hours too late on RI.Yeah, remote sensing and in situ recon data all point to Milton being in the initial stage of rapid intensification that will most like go uninterrupted barring any structural changes. Any call on lowest pressure? I could see a 40-50 mb drop occurring by tomorrow night. Perhaps we can't rule out an even lower drop before outer banding begins to intensify and influence the core. I'm going to say 928 mb is not unrealistic by tomorrow evening. 4 Link to comment Share on other sites More sharing options...

If this gets down to 928, then it will make cat 5 with how small it is...that is Andrew like. 1 Link to comment Share on other sites More sharing options...
Radtechwxman Posted October 7 Share Posted October 7 Surprised nhc is being more conservative with top strength Milton reaches in Gulf esp given how it looks tonight. I think 150-155 is a good bet and likely higher if good organization remains next day or so while Milton remains in favorable low shear and high OHC.

That is not my projected landfall intensity but it’s problematic because it’ll almost certainly trigger an ERC that expands the size of the hurricane—making both wind and surge risk worse. 8 Link to comment Share on other sites More sharing options...

Moderately Unstable Posted October 7 Share Posted October 7 6 minutes ago, allgame830 said: What is the lowest possible pressure in the gulf? I remember seeing information a while back that showed this. Well, *on record* that would be hurricane Rita. At a comfortable 895 mb. We won't be going into that department here, but, I am on the Kool-Aid train that this does ratchet itself up a lot. I somewhat despise prognosticating specific mb intensities. Please allow me to completely ignore and undercut that by saying I think this will peak between 925-935 mb. 2 Link to comment Share on other sites More sharing options...

Windspeed Posted October 7 Share Posted October 7 Keep in mind that core dynamics during RI and the atmospheric environment (ie atmospheric temps aloft) are also contributors to MPI, not just OHC.^ This x1000. As has been reiterated over the years, TCHP/OHC and their related maps are important for gauging MPI, but they're based on 26° isotherm depth and do not quantify upper atmospheric dynamics and storm motion for intensities. A slow-moving hurricane with average upper dynamics are aided greatly by depth of the 26°C isotherm. But immediate or near-to-surface temperature for fast moving systems are sufficient for an intense hurricane to avoid limitations of its own upwelling. Likewise, cooler than average upper tropospheric temperatures help to increase instability/atmospheric lift and lapse rates generated by slightly lower mean SSTs.Simply put, 28-29°C shallow layer SSTs should be plenty enough octane for Milton to reach even Category 5 strength if its internal structure doesn't get in the way of itself. It will be moving too fast for upwelling to be an issue now. And even if you account for a lack of deep content just north of the Yucatán, atmospheric conditions should remain favorable as the hurricane is crossing the loop current. However, Milton should have peaked in intensity by then and most likely will already have completed its first EWRC. 1 1 Link to comment Share on other sites More sharing options...

To this note I really think the only big thing that will limit Milton *is* shallow shelf waters as it passes near/south of scorpion reef. Link to comment Share on other sites More sharing options...
