Noway...EWRC has started...
no it hasn't....she has mainatained virtually the same ir signature all night...and if anything she looks as good as ever. ewrc is still probably 6 hrs away at the soonest

I hope not Jan.
The big question is what pressure will they find?

At 0800Z (2 a.m), they reported a 4 mile eye, and lower pressures yet. The new sea-level pressure was 884 millibars (26.11 in-Hg), measured by a dropsonde instrument. And realize, this was only a Cat 1 (70-mph) hurricane just nine hours earlier! The National Hurricane Center discussions had predicted the storm would intensify, but such "explosive deepening" is still phenomenal to witness.
This moves the rankings of this years storms as follows: Strongest Atlantic basin hurricane on record: Wilma (884 mb); Number 4: Rita (897 mb); Number 6: Katrina (902 mb). These are the strengths of the hurricanes at their peak, not landfall pressures. You can see a list of the strongest landfalling U.S. hurricanes at NHC website.
I haven't spoken to the crew yet, but the experience would certainly have been remarkable. With a pressure field so "tight", the crew would have felt the aircraft descending as they crossed the eyewall into the eye. Looking at the data from the aircraft, they lost 2680 feet of altitude during the eyewall penetration, in the five minutes it took to cross the eyewall into the eye. This is expected, and happens because the aircraft autopilot flies off an altimeter set to "standard" pressures (and this is anything BUT standard); we also have other altimeters that tell us how high we REALLY are, and using both types of altimeters is how we determine the pressures ("height of standard surface") at the flight level. In a "standard" atmopshere, the airplane would be at 10,000 feet, but in Wilma, they bottomed out at 6830 feet.

Those who live in the west coast of Florida now can go out and see the plane pass over you.Now plane is around 30 miles NE of Tampa.
