Location as of 3:47am CDT of a NOAA P-3 hurricane hunter aircraft performing a research mission into Hurricane Ida. At 3:40am CDT, an Air Force hurricane hunter aircraft departed from Lackland AFB in San Antonio, TX for a mission into the storm.

A NOAA P-3 hurricane hunter aircraft performing a research mission has reached the center of Hurricane Ida. Plane location as of 4:17am CDT.

[Chris_in_Tampa]

In northeast quadrant in HDOB set 11:

Flight Level Wind (30 sec. Avg.): 131 knots (150.8 mph)
Peak (10 sec. Avg.) Flight Level Wind: 134 knots (154.2 mph)
SFMR Peak (10s Avg.) Sfc. Wind:123 knots (141.5 mph)

They just entered the northeast quadrant so we need to see if there is a second wind maximum in next set at all or if that is highest.

That was the highest in northeast quadrant.

[Chris_in_Tampa]

First vortex message, and center sonde in first pass, had an incorrect extrapolated pressure in it and I removed it.

[Chris_in_Tampa]

In northeast quadrant at about 5:15am CDT:

Flight Level Wind (30 sec. Avg.): 137 knots (157.7 mph)
Peak (10 sec. Avg.) Flight Level Wind: 145 knots (166.9 mph)
SFMR Peak (10s Avg.) Sfc. Wind: 131 knots (150.8 mph)

Extrapolated surface pressures don't make sense. All the temperature and dewpoints are suspect. Don't trust the pressures.

Air Force recon just had 10 second estimated surface wind from SFMR, that was noted as suspect, at 140 knots (161.1 mph). It was where you would expect it to be in northeast quadrant though.
