Post-Tropical Cyclone Gordon


Recommended Posts

Gordon is up to a C2 per ATCF

105 mph

The real question now is if there is enough gas in the tank to get to Cat 3. There is an outside shot now given the recent rapid intensification. However, it would have to be in the next 6 hours or so as the shear is already starting to increase.

Hurricane Claudette in 1991 was cat 4 hurricane in that area, maybe a little south of that area

Nope, she was a 4 at around 61W, well west of where Gordon is. Charley was indeed the strongest hurricane around where Gordon is...and now Gordon has tied that...no majors have been recorded east of 32W.

I was going off of memory, just looked it up and my memory must be off because you're right, the track of that show it was a cat 1 hurricane so yes Gordon may become the strongest system this area has seen

Considering it was a direct hit, the wind reports from the Azores have been kinda so-so. The highest mentioned in the advisories is Santa Maria Island's 41 kt gusting to 61 kt. Even when making an allowance for the fact that the sustained wind is a 10-min value-- and therefore closer to ~47 kt if you convert to 1-min-- that's still kinda blah given that they got the core.

I wonder if they'll keep this a hurricane landfall in the Azores in postanalysis.

Noting Stewarts discussion of T and Td, ("not very tropical") strongest winds may not have mixed down to the surface due to relatively stable boundary conditions.

The airport in Santa Maria, Azores only reported every hour and didn't report wind at 4z tonight. It's likely there were stronger sustained winds in between hours, but i doubt there were hurricane-force sustained winds given the rapid weakening seen on satellite.

From the 11AM discussion

THE INSTITUTE OF METEOROLOGY IN THE AZORES PROVIDED A REPORT OF A

MINIMUM PRESSURE OF 980 MB ON SANTA MARIA ISLAND IN THE EASTERN

AZORES AS GORDON PASSED OVER THAT ISLAND THIS MORNING. A MAXIMUM

10-MINUTE WIND OF 53 KT WITH A GUST TO 70 KT WAS OBSERVED AT SANTA

MARIA AIRPORT.

Considering that's a 10-minute and not a 2-minute wind, that strongly supports that Gordon was still a minimal hurricane at the time of landfall in the southernmost Azores.

Agreed. That's the first I've seen of that reading. The previous advisories had much lower values, and I assumed the strongest winds had passed.

But the reports were definitely sparse from that station, so the high winds probably occurred between observations (esp since there was no 4AM wind obs).
