Expert predicts 14 named storms in 2007 ("above average activity")

FORT COLLINS, Colo. - The 2007 Atlantic hurricane season should have above-average activity, with three major hurricanes and a good chance at least one of them will make landfall, a top hurricane researcher said Friday.

Colorado State forecaster William Gray predicted 14 named storms and a total of seven hurricanes next year.

He and fellow researcher Philip Klotzbach said there is a 64 percent chance of one of the major hurricanes — with sustained winds of 111 mph or greater — coming ashore. The long-term average probability is 52 percent, they said.

Still, they said fewer hurricanes are likely to make landfall next year than in the devastating 2005 season, which had 28 named storms, including 15 hurricanes, four of which hit the U.S. The worst was Katrina, which leveled parts of the Gulf Coast.

The 2006 season had nine named storms and five hurricanes, two of them major. That was considered a "near normal" season but fell short of predictions by Gray and government scientists. None hit the U.S. Atlantic coast — only the 11th time that has occurred since 1945.

Gray and Klotzbach said last month that a surprise late El Nino contributed to the calmer June-to-November hurricane season this year.

El Nino — a warming in the Pacific Ocean — has far-reaching effects that include changing wind patterns in the eastern Atlantic, which can disrupt the formation of hurricanes there, Gray said.

Gray's team said Friday those conditions are likely to dissipate before the next season but Klotzbach cautioned, "this is an early prediction."

Gray said he believes the Atlantic basin is in an active hurricane cycle, despite the calm 2006 season.

"This active cycle is expected to continue for another decade or two at which time we should enter a quieter Atlantic major hurricane period like we experienced during the quarter-century periods of 1970-1994 and 1901-1925," he said.

Tropical Storm Risk, a London-based consortium of weather, insurance and risk-management experts, on Thursday forecast an active 2007 season, with up to 16 tropical storms including nine hurricanes, four of them intense.

I have a 20 sided die, can I play in this game too?

No, because your 5% chance of sucecss may throw off the curve for everyone else.

I'm going to wait to see what the folks from AccuWeather have to say. They got it right for 2006.

Huh? They were the biggest embarassing disaster of all.

AccuWeather predicted that the storms that formed in 2006 would move up the east coast and not enter the Gulf and that's essentially what happened.

Don't know if you all are interested, but Gray's forecasts for 2000-2006 didn't do any better than random forecasts. I got Gray's December forecasts for those years and actual data for 1995-2006 for NHC (I would have got more actual data but for prior years it's more difficult to pull out of the NHC web site). Then, assuming the named storms and hurricanes obey a Poisson distribution, I made a bunch of random forecasts, for each year using the mean of the actual data of prior years.

Gray's forecast for named storms was better ~28% of the time. His forecast for hurricanes was better ~49% of the time. (Better == smaller sum of squared differences)

Obviously the modelling isn't adding much value for Atlantic tropical storm prediction.
