    Transmission tower has collapsed, power lines to city down in the Mississippi river. I don't know if these are the very tall towers one can see from near the French Quarter crossing the river.

    Nobody deserves to die for stupidity, even if it is Clorox in the gene pool.

    Oil companies built canals in the swamplands to get drilling barges in, that messed up the fresh water/sea water mix. The nutria, brought for fur, eats marsh grasses, and the logical predator to keep them in check, the alligator, doesn't seem to have a taste for nutria. A lot of 'land' South of NOLA is open water, not even swamp. One reason Ida is slow to spin down just inland.

    South Louisiana is unnatural, and while the reasons were good, the unexpected affects, bad. The Mississippi changes its main channel to the Gulf every few hundred years. It would have about a century ago but they built a structure to limit flow down the Atchafalaya, where the river was about to switch to, from the main channel to protect shipping in BTR and MSY/NOLA. They also build many flood levees. Now each year, during Spring rain and snowmelt, sediment gets carried to the very tip of the river to extend the delta, and soft sediment compacting a cm or more a year are not getting new sediment. Reduced annual flow, but at a cost. Similar for Galliano and Golden Meadow, Bayou Lafourche is a distributary of the Mississippi, a flood control structure was built to stop annual floods along the bayou. Those towns don't flood anymore, which means new sediment doesn't keep ground levels even as the soft sediment beneath compacts.

    Google usually helps. GPM sounds like a unit of speed or fluid flow, not altitude. Oh, 954 mb, the ADT was w/i 1 mb of interpolated plane pressure.

    Eye wobble W on satellite. Probably a trochoidal wobble, or whatever it is called in stronger storms, but enough of those can add up (if it doesn't have as many corresponding N wobbles), and sparing the most people the eyewall is a good thing.

    Is 'GPM' on the Tropical Tidbits recon page just a reference to meters. Is this plane 3 km up? Altitude: 2989 gpm

    30 knot plus sustained 10 meter (buildings will get that to street level, I'd think) winds in NOLA by 18Z, 80 knot 850 mb winds just South of MSY itself, or gusts to hurricane force not much over a day away. (6Z HWRF)

    I believe in the day the UN WMO didn't approve a list. The late Dr. John Hope, of TWC, the original 1980s tropical met, contributed the name 'Camille' to the 1969 storm name list because he had a daughter Camille.

    How many days of fuel do hospital emergency generators have is another question. Pretty sure there are still COVID patients on ventilators. I caught the Rona in December, and have apparently permanent hearing damage, constant tinnitus, and occasional bouts of vertigo. I was sick at home during the cool season for almost 3 weeks, trying to imagine that in early September heat w/o AC. That would have been ugly, and I was never on a vent.

    It was fuzzy before yesterday, but New Orleans as a danger zone was known by yesterday afternoon, how long does it take to contra-flow I-10 and I-55? The reason they are not ordering mandatory evacuations of New Orleans. Maybe they get lucky and it misses wide right or wide left, or splits the uprights and the levees hold, but even if they don't flood, but I'm seeing 70 knot plus 850 mb winds, which I assume is a safe guesstimate for wind gusts, or, even if the don't flood, anyone whose power isn't from underground cables will have no utilities for a week or more.

    Eye not well defined last VDM, and I can't see it on satellite, but pretty sure that is temporary.

    Ida won't have 72 hours over the Gulf. New GFS looks a smidge West of worst case for NOLA on track. A smidge. St. Mary parish. Still bad, just not worst case. Looks like ensembles all in Louisiana. I think Western Vermillion parish, assuming a major, affects the least number of people in Louisiana. Op GFS over 15" rain near landfall, less than 3 inches in almost all of Tennessee, although they probably don't need any rain for a few days.
  15. Ed, snow and hurricane fan
    18Z Euro ensembles, with balloon sonde data from all over the SE USA and aircraft data, now very well clustered, Central Louisiana to Mississippi. Vermillion parish seems like a best case scenario, Abbeville, New Iberia and Morgan City would have surge issues, Lafayette would have wind issues, but a lot less people affected, especially with no mandatory evacs for NOLA, than Lafourche, Terrebonne or Jefferson parish would mean. Brief West trend seems, eyeball, to have been countered by a NNW trend this evening. Waiting on aircraft center fixes to be sure.
  16. Ed, snow and hurricane fan
    New Iberia is on the East side of Vermillion Bay, Ida would almost have to bend back East just before landfall. I used to walk around the cane fields at ARA just North of New Iberia during lunch.

    Maximum Sustained Wind Overall (mph): 145 mphMaximum Sustained Wind at Landfall (mph): 140 mphPressure at Landfall (mb): 937mbLandfall Location: Cocodrie, Terrebonne parish. I spent a week offshore on a barge rig. Came back, flat tire, cracked sidewall from horrible Louisiana roads, horseflies biting like mad putting on the donut, Cocodrie to Lafayette on a Sunday driving on a donut on US 99. (1998)

    Someone I think might be a Juggalo was talking about taking his kids to chase in New Orleans and see a Cat 5. Might be in the other thread Grape Faygo or some such name. That he has bred already is disappointing.
  19. Ed, snow and hurricane fan
    I was replying to someone saying Cat 1. It has time to Harvey, I don;t think it gets Cat 5. I could be wrong.
  20. Ed, snow and hurricane fan
    I won't have time to go full Cat 5, or even Cat 4 (maybe borderline Cat 3/4, tops) passing over high SSTs/OHC and light shear, Cat 1 seems low. Even w/ less than 2 full days over the Gulf.
  21. Ed, snow and hurricane fan
    Banter-ish, but the governor should cancel school in Louisiana, and have every bus driver in the state congregate, maybe somewhere on I-49 North of Lafayette, so whether the track shifts back to Lake Charles or New Orleans, they can be doing mass evacs to Houston. Yes, they'll be big overtime for the drivers. But I remember late month for Katrina meant people on fixed incomes at the end of the month didn't have gas or hotel money to evacuate.
  22. Ed, snow and hurricane fan
    Can't argue with climatology.
  23. Ed, snow and hurricane fan
    Unless the forecast of the mean ridge by GFS/Euro over Carolinas is really messed up, it might hit the Western Panhandle but the peninsula seems very, very unlikely.
  24. Ed, snow and hurricane fan
    45 knot FL winds not too far off Jamaica, an upgrade would seem likely. Ridge position in ensembles, peninsular Florida doesn't look like it could happen, but a shift East to even Pensacola is possible if that MLC is the where the LLC forms, which seems likely.
  25. Ed, snow and hurricane fan
    I still a small exposed swirl SW of where the likely center is. No storms, it will die, but 9L is not super organized quite yet,
