at this point it feels more like the expected solution

A 12 Degree Celsius temperature difference between inside the eye and outside of the eye. Oh my, that’s so not good.

Too early, sorry 135 knots

Would this make it official? Cat5?

The dreaded-yet-classic Cat-5 “donut”-type core is becoming glaringly evident on NEXRAD at an alarming rate, as was seen in Andrew and Michael.

935 mb looks like the real number for pressure.

[aspen]

948mb/98kt from that weird NOAA dropsonde…what pressure would that support? 940-943mb?

Now that’s a pure nightmare for those people in SE Louisiana, every hour it gets worse.

[KBBOCA]

Damn. Eric Blake's wording just gets even stronger..... I feel sick along with him.

The eye has fully cleared out now, I expect this to facilitate an even further drop in pressure.

[Shell Mound]

Now that’s a pure nightmare for those people in SE Louisiana, every hour it gets worse.

Sadly, given the long-term and short-term movement, I think the eastern eyewall is likely to affect at least the western part of NOLA proper.

Wow, Ida is about to throw Laura and the 1856 Last Island Hurricane off the strongest Louisiana landfall throne. Absolutely crazy.
