Atlantic hurricane season records signals climate change implications

An average season has 11 named storms, six of which become hurricanes. This year there were eight hurricanes, of which five - Bertha, Gustav, Ike, Omar and Paloma — became major hurricanes.

Three of those — Gustav, Ike and Paloma — made "extreme" Category 4, where winds have to be at least 131 mph. "That's a lot," Bell said. "But it's typical of a very active season such as what we saw."

Curry said this year's large number of Category 4 storms indicates a "signal" of global warming.

NVDL: Call it gut feel, or intuition, but this blog also predicted a record breaking season even when the 'experts' expected 'average' conditions.

Three records showed the hurricane season's relentlessness. Six consecutive named storms — Dolly, Edouard, Fay, Gustav, Hanna and Ike — struck the U.S. mainland, something that had not been seen in recorded history. It's also the first time a major hurricane, those with winds of at least 111 mph, formed in five consecutive months, July through November. And Bertha spun about for 17 days, making it the longest lived storm in July.

Two records involve storms hitting the same places repeatedly. Rain-heavy Fay was the only storm to hit the same state — Florida — four times, leaving heavy flood damage in its wake. A record three major hurricanes smacked Cuba: Gustav, Ike and Paloma.
