  1. Wow, that's pretty gnarly then. Wasn't immediately obvious that it was going to be quite that bad up there -- but the radar structure on landfall was still pretty tropical in appearance with a partially intact eyewall.
  2. How was it up there -- as compared to say a strong mid-winter cyclone?
  3. After looking at the METAR list, it sure looks like it.
  4. I see the MSY wind sensor got knocked out. Ugh, not great.
  5. Starting to get real in NOLA: METAR: KMSY 292240Z AUTO 09054G72KT 1/4SM +RA OVC012 25/ A2905 RMK AO2 PK WND 08076/2208 LTG DSNT S PRESFR P0023 T0250 RVRNO $
  6. The breakdown of the vortex rossby waves in the eyewall over the past 30 minutes is like something out of a textbook. Also waves propagating out from the center into the rainbands (obvious from radar loop).
  7. Yeah, I was premature on the bank call. Either wobbling or getting some frictional torqueing as it interacts with the coastal interface -- but whatever it is, we'll take it.
  8. Yeah, cam is tilted now, but somehow still up.
  9. Can't be sure yet -- but she looks to be banking slightly right relative to earlier. Might be the start of the turn.
  10. Saw that cooler and other trash. Sherriff of Grand Isle on the phone on TWC said their sensor reached 148mph (prob a gust) before breaking.
  11. That's what I thought too -- but he clipped the GIF version instead of the flash version of ADDS, which indeed uses whole integer numbers for SLP (the flash version uses the tenths, like in METARs). Still, the lowest I can find from the station's METAR record is: KCYD 291035Z AUTO 1/4SM -RA FG OVC004 27/26 A2809 RMK A02 P0002 T02710260 Which is about 951mb. The issue is that the station didn't report an altimeter for 90m prior to that and it was on the way up -- so we don't really know.
  12. Shear vector is out of the WNW. Only around 8-12kt, but that's enough to place more of the precip on the E/SE side of the circulation.
  13. At least some of them from my recollection, yeah. I recall reading some papers on those two in particular and how normal FL wind reduction to the surface wasn't always appropriate.
  14. Acting like Dean and Mitch with these wind profiles. Max warm core strength closer to the surface.
  15. Yes, it was. Around 105-115 max intensity. We're going to clear that in terms of max w and radii, which will have an impact on those initial numbers. The levees will likely hold, which is why I said "risk". Additional strengthening will not help though and the increase in risk is not linear.
  16. Every storm in this rarified air is different. Katrina's surge will be hard to beat due to its gaping maw and cat 5 intensity well before landfall, which allowed a significant swell and surge to build before it made landfall (it weakened only very shortly before landfall). Ida has had less time, even though it will be stronger in terms of max wind. I suspect the wind damage will be the standout with this one -- though the surge on any cat4/cat5 is no slouch either.
  17. Really beginning to think that Nora screwed the pooch. The push from differential shear on Fri-Sat morn plus the outflow push from Nora into the TUTT over the western GOM has really left this in a bad spot. We need a lucky break now.
  18. I was expecting stronger when I got up this morning, but this is definitely over my guess. We need an EWRC and fast. Main hurricane levees are at risk at this level. Any more strengthening will not help in that regard.
  19. T-numbers shooting up: 5.6 current, 6.1 raw; Satcon showing major (100) with hourly up to 105kt.
  20. Pretty obvious strengthening ongoing atm with the storm crossing a warm eddy (as part of the Loop Current). Eye looking to try and clear out with a more classic look likely soon, given deep convection has wrapped around the center.
  21. The TUTT cell to the west has finally started sinking south in the last couple of hours. We should start seeing a more westerly component to motion now (finally).
  22. Won't matter unless it can get ingested. She's sitting in a large moisture envelope and under low shear. Pretty well buffered at the moment.
  23. Yeah no kidding. Kind of need that right now. Ida has *kind of* taken her time getting re-organized today, so I imagine we're not quite getting the extra boost. There's a bit of an easterly shear vector in the mid-upper levels tonight and RI should be fully underway. Hoping that gives her a nudge back to the west before LF.
  24. She's still leaning east-of-prog and the margin for NOLA taking the NE eyewall is getting razor thin. I keep saying this, but it needs to stop and soon.
  25. Hah, I wondered where you were at. Yeah, it's been slowly symmetrizing all day after being a bit tilted and asymmetric this morning. Should be able to take advantage of its improved structure tonight.
