No.... Just saw it on The Weather Channel.... Via a webcam they  showed..

This is gonna make Katrina look like little league I fear.  This is a complete monstrosity…and strengthening as it’s making landfall as quite possibly the strongest ever on top of it.  Holy smokes what a storm. 

Katrina was also *BAD* for reasons well outside of just the “hurricane being intense.”

Katrina will always been in a league of its own. I suppose it’s conceivable that some day it gets beat, as all records are meant to be broken, but don’t think this is the angle of approach to do it for NOLA. LIKEWISE, some of these smaller towns east of the eye could be wiped off the map… sadly.

I'm pretty hopeful the levees won't fail this time around.

I hope he set this feed up and LEFT. This is not survivable.

Of course…but this is gonna be SUBSTANTIALLY STRONGER which wherever that NE Quadrant comes in will just scour what towns are there…this is gonna be worse.

I'll take this to banter if need be, but we have seen that these chasers aren't always the smartest people. There was one dude who literally almost died in Mexico Beach during Michael.

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.

They said "little to no storm surge flooding expected" and that forecast was based on rapid intensification.

Need to hope it comes on shore at low tide.

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.

Well high tide is roughly 8am there so..

[WhiteoutWX]

Maybe a bit of a westward jog last 30 minutes? I think NOLA proper dodges the brunt of the eyewall at this point. Maybe western sides of town get scraped by it. They need every westward wobble they can get though.

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.

Yeah, you're probably talking about a surge approaching 20 ft at the mouth of the Mississippi here as opposed to 28 ft observed in Katrina in Mississippi.

138kt FL wind, 129kt SFMR. Not quite enough yet to push us into Cat 5 territory

I was thinking the same, more WNW.

[dan11295]

I also agree I think most of NOLA proper avoids the eyewall. Western suburbs (Kenner, Laplace,etc.) probably wont be so lucky.

[jojo762]

NOAA plane also found a 147kt FL wind (~170mph).

[STxVortex]

Hurricane Ida has TS wind field nearly 450 miles in diameter, hurricane force wind field is nearly 150 miles in diameter. That is going to scour a lot of territory.

I think Ida may finally be leveling off. Albeit still in warm waters, the OHC near shore is not nearly as impressive as it was in hours ago and absolutely exploded. Regardless, this is going to be catastrophic.

The eye continues to warm and the pressure continues to fall. It’s not leveling out yet.

928.3 extrapolated on last pass.

[taylorsweather]

Will the shape of the coastline as Ida approaches cause any wobbles left or right, and any contraction in the eye  due to frictional effects?
