Re: ATL: ZETA - Hurricane - Discussion
When was the last time a hurricane went DIRECTLY over New Orleans. I know there have been significant impacts with near misses over the years.

I think the landfall moved a bit west though to between Fourchon and dularge area. I’m thinking between Fourchon and Morgan city is in play. I just hope we get the eastern side because if it comes in over or just west of us NOLA will catch the eastern eye wall maybe.
No one listen to me I am just a long time tropical weather buff. I have no training in meteorology at all!!
While not a major storm, the windfield is large. You may very well have worse conditions and higher surge being east of the center than you would taking a 'direct' hit.
My projection is the storm surge may catch many off guard given how big the windfield is.

You may be discounting the effects of baroclinic enhancement. There is a clash of air masses, and that typically that enhances extra-tropical storms. The question is does Zeta degrade from that or enhance. Normally an east coast thing, but the dynamics are not far off.

It’s already got an eastern component. You don’t want to put money on that prediction unless you can get odds too good to pass up - like 100:1.
Of Coarse the tip of Grand Isle will be first landfall but second in the area of Gulfport to Biloxi . I wonder if Vegas would take the bet .
Haha. For sure. I haven’t been convinced one way or the other on MS. Models were pretty split in taking this either to the Hancock/Harrison Co Coasts or just moving it up through Slidell/Pearl River. I still can’t make up my mind on it though I do figure Hancock/Harrison/Jackson and even Mobile Counties are going to get a solid lick from Zeta.

Memory is mostly shot but probably Florence 1988. Bill in 2003 was a TS. Isaac ‘12 was close but passed south of the city. Same with Betsy in 65.

Re: ATL: ZETA - Hurricane - Discussion
This is not a large hurricane. Hurricane-force winds do not cover a large area, and are mostly east of the center (out to 30 miles or so). Tropical storm-force wind radii are just about average for an Atlantic hurricane. This is not Katrina. It will not produce a surge that overtops the levees in New Orleans. I think the NHC is being very generous with that 80 kt (90 mph) wind in their latest advisory. Probably closer to 75 kts, but they may be going 80 kts because they expect a little strengthening prior to landfall (baroclinic enhancement, which has been mentioned).

Thank you! I knew Isaac went south because it was out near Morgan City I think. Betsy I wasn’t sure about.

Betsy was much larger, passed well south, and came from the SE vs. SW. If you wanted to pick a "good" direction for a hurricane to hit New Orleans surge-wise, it's from the SW.

I just noticed that the push is starting to happen from the west now. The further west the front pushes will cause Zeta to go more east and north at a faster pace. East side will def. be problematic for points to the east. Im no pro by any means but after watching for 20 yrs plus , I just observe the over all picture. I hope everyone is safe and prepared for the storm. If winds are 100 at landfall and moving at 25 to 30 mph , better figure to add those winds on top of forecasted winds !!

NHC still at 90 mph because of flight level winds of 89 knots.

Re: ATL: ZETA - Hurricane - Discussion
Five hits in one year is simply amazing. My question is do Grand Solar Miniums enhance hurricane activity? It's been 150 years and the technology was not quite as good as today. We will be in this for another 35 years so I hope someone is studying the issue because if they do enhance, it will be another weather issue to add on to the rest of the misery. What a season regardless! Best of luck LA and points north, going to be a pretty decent punch, but also quite manageable if you are prepared.

SW eyewall also drying out. Big drop in humidity as well.
NE eyewall saturated.
Dry air getting into the core now.
I think it sucked some dry air in this morning but seems to be back on track which isn’t good. Turn baby turn, selfish I know.

Re: ATL: ZETA - Hurricane - Discussion
Who said this was a large hurricane? Who compared this to Katrina? Also, your condescending comments towards the NHC are getting old. And it’s especially dangerous in the midst of a landfall.wxman57 wrote:This is not a large hurricane.

Re: ATL: ZETA - Hurricane - Discussion
The rap around process with a cleared out eye is nearly complete. The satellite presentation we are likely to observe in about two hours is usually indicative of a major hurricane.....? https://weather.cod.edu/satrad/?parms=r ... =undefined
