-(I think) the lowest ACE for a Category 5 Atlantic hurricane (12.8).
-One of only three Atlantic Category 5 hurricanes with an A name, and the only female name to have done so. (the others were Allen and Andrew).
-The last retirement of a name prior to the new male/female name lists.


1977 was an inactive year. I never knew why and I have tried looking for information about it. All I know that we had a very weak El Nino that time and monsoonal pattern may have been further south that time. I know the Philippines was dry in 1977.


but you know, all the basin's in 1977 were quite inactive for an unknown reason... even the WPac

one question: how far east did a hurricane reach Cat. 5 status? :?:

(I'm assuming you mean the Atlantic)

I'm not sure of the exact position, but someone else can tell you that.

Hmmm not sure I believe Cleo was cat-5 for that matter with a central pressure of just 948mbs, or in other words about the same pressure as Bertha and the other issue is recon was still in its early days at that time I believe.

Or was the lowest pressure ob/estimate taken before it got much stronger?

Quote from the Wiki- "The hurricane's strongest winds were not documented, so it is assumed that the cyclone reached its peak strength during the day."

So, probably.

I think the second furthest east was Isabel.

Cleo's minimum central pressure (948 mb) was measured by reconnaissance aircraft. The reading coincided with Cleo's estimated maximum intensity and strongest 1-min winds (140 kt/160 mph). Since evidence suggests Cleo did not feature an exceptionally narrow wind radii, the gradient balance does not support maximum sustained winds remotely close to Category 5 strength. Although reconnaissance likely did not sample the maximum flight level winds, the preceding information still does not suggest Category 5 1-min winds. Additionally, Cleo attained its maximum intensity between 18-22 N, which is relatively far north. The TC was recurving at this time, and it was entering the (typically) weaker ambient pressures present in the subtropical North Atlantic. Overall, Cleo was likely MUCH weaker than Category 5 status.

i think it was Hugo... I also think that Hurricane Dog was a hurricane that maintain cat. 5 strength at the most northern latitiude ever than any cat 5...

All accounts suggest Dog was NOT a Category 5 hurricane, though I believe it still attained major hurricane status.

Reputable studies have suggested TCs were overestimated (and underestimated) prior to the 1980s.

According to an FAQ I saw once at a NOAA site, Faith, John, and Ophelia hold the Atl, EPac, and WPac track records, respectively. Of the three, Ophelia travelled furthest, followed by John, then Faith.

Whack-a-cane: (Imagine God with a mallet giving it a whack every so often.) Similar track to Katrina in Bahamas/Gulf.

Goin' South!

you mean THE most. Ethel may very well of never even been a major Hurricane in the first place.

Forgot the name of the storm that hit Brazil. And I dont know if there was more than one that hit that country, but its impressive to have something there.
