FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

HURRICANE ALEX WAS THE ONLY TROPICAL CYCLONE OBSERVED DURING THE
MONTH OF JUNE AND THE FIRST JUNE ATLANTIC BASIN HURRICANE SINCE
1995. IT WAS ALSO THE FIRST CATEGORY TWO JUNE HURRICANE SINCE 1966.
ON AVERAGE...A TROPICAL STORM OCCURS IN THE ATLANTIC BASIN IN JUNE
EVERY OTHER YEAR...AND A HURRICANE ABOUT ONCE EVERY FIVE YEARS. ALEX
MADE LANDFALL ALONG THE NORTHEAST MEXICAN COAST IN THE MUNICIPALITY
OF SOTO LA MARINA LATE ON 30 JUNE AS A CATEGORY TWO HURRICANE ON

FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..

JUNE WAS A VERY ACTIVE MONTH IN THE BASIN WITH THREE TROPICAL STORMS
OBSERVED...TWO OF WHICH BECAME HURRICANES THAT EVENTUALLY REACHED
MAJOR HURRICANE INTENSITY. THIS COMPARES TO THE LONG-TERM AVERAGE
OF ABOUT TWO TROPICAL STORMS AND ONE HURRICANE EVERY YEAR...AND A
MAJOR HURRICANE ABOUT EVERY OTHER YEAR. USING THE ACCUMULATED
CYCLONE ENERGY INDEX...ACE...WHICH MEASURES THE COMBINED DURATION
AND STRENGTH OF TROPICAL STORMS AND HURRICANES...2010 HAD THE
HIGHEST JUNE ACE VALUE ON RECORD...ECLIPSING THE PREVIOUS RECORD IN
1984...AND WAS MORE THAN THREE TIMES THE LONG-TERM AVERAGE. ONE
SHORT-LIVED TROPICAL DEPRESSION ALSO FORMED.

[Macrocane]

What an impressive start of the seasons, North Indian ocean experienced a very active start as well, the only one that has been unimpressive is the West Pacific.

[KWT]

Quite impressive to see how much ACE Alex brought in for a June system, its certainly been a decent start to the NH season thanks mainly to the active June in the EPAC/

[Ptarmigan]

Number of storms and ACE are not always related. 1936 had 16/7/1, but an ACE of 108. On the other hand, 1961 had 11/8/7, but an ACE of 205. Higher ACEs are largely from hurricanes and major hurricanes.

[CrazyC83]

There could be 28 named storms, but if they were all short-lived tropical storms, the ACE wouldn't be that high. But if there were 10 named storms (a slightly below average year) and most or all of them were long-lived major hurricanes, then the ACE would be beyond hyperactive.

[Cainer]

Probably 2 of the best example that show the difference between ACE and # of storms are 2006 and 2007. 2006 was 10/5/2 with an ACE of 78.5, while 2007 was 15/6/2 with an ACE of 71.7, even less than 2006. Just goes to show that even some notorious seasons were relatively quiet, ACE-wise.

Anyway, you can't say that it was a boring June, that's for sure... there's been something to track constantly since TD-2E formed in the middle of the month, not to mention a CAT5 and of course Alex!

[KWT]

Yep, though outside of Dean and Felix there really was nothing of note in the 2007 season, it was such a contrasting season, those two storms were monsters, everything else that season really wasn't worth even developing really!

Impressive to get a June ACE record in the EPAC, bet its been a while since the EPAC set that sort of record...

Hurricane Noel was notable, it was the deadliest of the season though it was "only" a category 1.

[KWT]

True I suppose it was noteable for its deaths sadly, but most certainly not for its strength which was what I was really talking about in that post.

As I said outside of Dean and Felix, nothing even reached category-2 outside of those storms.

[Macrocane]

Yes it was a weird season, I wonder what happened after Felix that inhibited the development of the systems, I think that if Humberto and Lorenzo would have spent more time over the Gulf of Mexico they could have been major hurricanes.

By the way, why are we all discussing ACE vs number of storms, who said that ACE was always related to the number of storms?

[Ptarmigan]

CrazyC83:
Very true.

Macrocane:
I felt like emphasizing number of storms and ACE are not always related. They are strongly correlated though.

You're very right, I just found kind of funny how we changed the topic.
