Re: Hurricane Dolly Approaches Brownsville

It looks like we're about to get a new one below 975.. and still falling.

Surprising that winds aren't yet much higher than 80-ish. This almost has to change, shortly.

Close-enough.. Here's a bit of the 4AM Discussion

500 AM EDT WED JUL 23 2008

AIR FORCE HURRICANE HUNTER DROPSONDE OBSERVATIONS INDICATE THAT THE
CENTRAL PRESSURE HAS FALLEN TO 976 MB...A RATHER SIGNIFICANT
DECREASE OVER THE PAST COUPLE OF HOURS. ALTHOUGH THE SFMR...
DROPSONDE...AND FLIGHT-LEVEL WIND MEASUREMENTS UP TO NOW HAVE
YIELDED 70 KT FOR THE CURRENT INTENSITY...I HAVE TOO MUCH RESPECT
FOR THIS ABRUPT FALL IN PRESSURE TO NOT SHOW ANY INCREASE IN
STRENGTH. THEREFORE THE CURRENT INTENSITY IS ADJUSTED TO 75 KT FOR
THIS ADVISORY. WSR-88D DOPPLER RADAR FROM BROWNSVILLE SHOWS A
BANDING-TYPE EYE THAT IS TRYING TO CLOSE OFF ALONG WITH AN INCREASE
IN FEEDER BANDS OVER THE PAST SEVERAL HOURS.
