Not sure if this was meant for someone specific, but I and other S2K folks are here in New Orleans with our families/friends and not evacuating. I do have friends who left or extended vacations out of town to avoid the storm. We have many streets and neighborhoods that experience minor flooding during heavy (but normal) rains. If I lived in one of those areas and had young children or other vulnerable folks in my household, I would have considered leaving, but for convenience and comfort as much as safety.



Sue,
Thanks very much for your reply. So, it sounds like you're saying the flooding will not be anything near as bad as Katrina. I was overly worried because the river is already supposedly close to overflowing its banks and there could be 1-2 feet of rainfall in addition to storm surge.

Meso-vortex can have lower pressures than the actual center because they are basically large tornadoes that have lower pressure, but still not be the true center. The true center can and does have multiple vortexes that come and go. So I am not trusting those smaller vortexes, I am going with the center of all of those to be the true center, and it won't be coming to landfall for at least another 12 to 24 hours depending on exactly it comes in.

Will it be a offical landfall if the LLC shooting NW makes landfall?

We are hoping that it won't be nearly as bad as Katrina, but we really can't tell you the exact extent of flooding for this system due to many different circumstances that will accumulate all together.

Time to play connect the swirls.
Obviously in a larger gyre.
Need to really look at this on Rapid Scan

If I'm not mistaken, a official landfall won't be until the official center comes completely across land.

I bet the NHC guys and gals are extremely frustrated right now. This is crazy.

it hasn't peaked in intensity, and it's not going to until sometime on the 14th. We will hopefully stay safe here though.

Yup, as a matter of fact you can see the LLC now going more westerly in the latest imagery.

This is just my personal opinion: flooding events tend to be worse than forecast. For tropical systems, I always assume the worst. Based on what I’ve seen, if I lived there, I wouldn’t chance it. It’s a catastrophe that’s being prevented by a shoestring network of canals and levees. They have failed before and will fail again. With the river already at bankfull and the storm hasn’t even started yet...I’m pretty worried about New Orleans. No way I’d stay inside that bowl.


We're not really worried about the river levees here. Points where they could overtop are all downriver from here. I didn't want to hotlink the map, so I'll just post a link to the story that has the map.

I'm way more worried about a rain threat, though many of the globals and the mesoscales have nudged that 35-40 miles west of where it was depicted yesterday.

So does this justify 65kt at the next full advisory?
