This is a good find for sure.

Hugo at peak intensity or close to it.. 162 kt at flight level.. probably 145 kt today! (best track has 140)

Is that multiplied by .70 cause of the 700MB ? Or what is it multiplied by?

[benny]

that's not mutiplied by anything. that is the actual max flight level wind in the storm. usually multiplied by about .9 to get the estimated surface winds.

[SouthFloridawx]

that's not mutiplied by anything. that is the actual max flight level wind in the storm. usually multiplied by about .9 to get the estimated surface winds.

That's what I wanted to know benny thank you, as I am not experienced in recon data. So you take that flight level wind and mulitply it by .9 to get the estimated surface wind?

In that case the estimated surface wind would have been 175.95 MPH wow. I realize it could have been a gust or something like that but, still.

[benny]

yup the official best track now reads 150 kt at that time.

[Derek Ortt]

about the Hugo FL info

the 162KT came from 1500 feet, according to the NHC tropical cyclone report, not 700mb.

the result of one flight too low into Hugo was nearly disaster

[CHRISTY]

how's this for recon data!this is the night i never went to sleep!

HURRICANE WILMA TROPICAL CYCLONE UPDATE
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
230 AM EDT WED OCT 19 2005

DATA FROM A RECONNAISSANCE AIRCRAFT INDICATE THAT HURRICANE WILMA HAS BECOME AN EXTREMELY DANGEROUS CATEGORY FIVE HURRICANE ON THE SAFFIR-SIMPSON HURRICANE SCALE. THE RECONNAISSANCE PLANE MEASURED
175 MPH WINDS AND ESTIMATED A MINIMUM PRESSURE OF 892 MB. THIS IS THE LOWEST PRESSURE OBSERVED IN 2005 AND IS EQUIVALENT TO THE MINIMUM PRESSURE OF THE 1935 LABOR DAY HURRICANE IN THE FLORIDA KEYS.

[Scorpion]

Nice! This is great news!

[Scorpion]

By the way, wouldnt 170 kts for Andrew result in near 155 kts?

[CHRISTY]

...BASED ON DROPSONDE AND FLIGHT-LEVEL DATA FROM AN AIR FORCE PLANE JUST RETURNING FROM ITS MISSION IN WILMA... THE MINIMUM CENTRAL PRESSURE IS ESTIMATED TO BE 882 MB... 26.05 INCHES... THIS IS THE LOWEST PRESSURE ON RECORD FOR A HURRICANE IN THE ATLANTIC BASIN.


...AIR FORCE RECONNAISSANCE PLANE REPORTED* 884 MB... THE LOWEST MINIMUM PRESSURE EVER MEASURED IN A HURRICANE IN THE ATLANTIC BASIN... THIS VALUE SHOULD BE USED WITH CAUTION UNTIL CALIBRATED...

DATA FROM A RECONNAISSANCE AIRCRAFT* INDICATE THAT HURRICANE WILMA HAS BECOME AN EXTREMELY DANGEROUS CATEGORY FIVE HURRICANE ON THE SAFFIR-SIMPSON HURRICANE SCALE.
