Don't touch that button!!!

Dec, 04: 11 - 6 - 3

Apr, 05: 13 - 7 - 3

Jun, 05: 15 - 8 - 4


Whoa that's really weird each number of storms goes up by 2 and the hurricanes numbers go up by 1 and look at his new forecast:17-9-5 the hurricanes section is one higher from last years and the storms section is 2 higher than last years. :eek:

The discussion is pretty straight forward in the forcast. Do take about 20 minutes to go through and read it because it's pretty good information. Not that often do we get insight into why they are forcasting what they are.

It isn't up yet and given it is 3:35pm here if it isn't there within the next hour and a half I don't expect it will be up today.

"During periods of positive North Atlantic SSTA, a higher percentage of Atlantic basin major hurricanes cross Florida and the eastern U.S. coastline for a given level of NTC. U.S. hurricane landfall probability is thus expected to be well above average owing to both predicted above-average NTC and above-average North Atlantic SSTAs."

Ominous statement for Florida and East US coast.

7.2 Forthcoming Revised Landfall Prediction Scheme



We have recently been investigating the potential predictability of steering current patterns likely to be present during the upcoming hurricane season. No individual or group can accurately predict exactly where or when a particular storm will make landfall months in advance; however, we have found that using a combination of our NTC forecast and several April-May steering current predictors, we can improve our landfall probability scheme considerably. We are currently working on documentation of this revised landfall prediction scheme, and it will debut with our 31 May update of the 2006 hurricane forecast.



Yes, this immediately jumped out at me too.

Very much looking forward to their reasoning.

MIAMI, Florida (Reuters) -- The 2006 hurricane season will not be as ferocious as last year when Hurricane Katrina devastated New Orleans, but will still be unusually busy, a noted forecasting team said Tuesday.

The Colorado State University team led by Dr. William Gray, a pioneer in forecasting storm probabilities, said it expected 17 named storms to form in the Atlantic basin during the six-month season starting in June.

Nine of the storms will likely strengthen into hurricanes, with winds of at least 74 mph, the team said, reaffirming their early prediction in December.

The forecasters said five of the hurricanes were likely to be major storms, reaching at least Category 3 on the five-step Saffir-Simpson scale of hurricane intensity, and boasting winds of at least 111 mph.

But they also said there was less chance of major storms making landfall in the United States compared with 2005's record-breaking hurricane season.

"Even though we expect to see the current active period of Atlantic major hurricane activity to continue for another 15-20 years, it is statistically unlikely that the coming 2006-2007 hurricane season, or the seasons that follow, will have the number of major hurricane U.S. landfall events as we have seen in 2004-2005," Gray said in a statement.

Last season -- at $80 billion the costliest on record in terms of damage -- saw 27 named storms, of which 15 developed into hurricanes.

In addition to Katrina, Hurricane Rita hammered Texas and Hurricane Wilma briefly became the most intense Atlantic hurricane ever observed before slamming into the Mexican resort of Cancun. Wilma then curved back over South Florida, where it wreaked $10 billion worth of damage.

The long-term statistical average is for about 10 named storms per season, of which six become hurricanes.

This is by far his most agressive April Forecast. For him to predict 17/9/5 at this point is pretty amazing. 5 Intense Hurricanes is nothing to sneeze at.

2005 changed the way meterologists look at the tropics

One of the changes they made was for the analog years. Dec forcast used 61, 67, 96, 99, 03. In Apr forecast he dropped 61 and 67 and went with 64, 96, 99, 03. Didn't improve the outlook for NC though. All years included at least one NC landfall, darnl.

SOME INTERESTING STUFF ABOUT LA NINA AND THE CURRENT DROUGHT CONDTIONS...

THE REASON FOR THE UNUSUALLY DRY CONDITIONS AND THE ONSET OF A MODERATE AGRICULTURAL DROUGHT IS BELIEVED TO BE LINKED TO THE LA NINA PHENOMENON OF THE EQUATORIAL PACIFIC OCEAN. COOLER THAN NORMAL WATER TEMPERATURES ALONG THE EQUATOR IN THE EASTERN PACIFIC OCEAN ALTERS THE TRACKS OF STORM SYSTEMS TO WELL NORTH OF THE GULF STATES...THEREBY LIMITING THE OPPORTUNITIES FOR TYPICAL RAIN EPISODES. THE CURRENT LA NINA CYCLE IS CONSIDERED TO BE WEAK. COMPARABLE YEARS WITH SIMILAR LA NINA CONDITIONS SINCE 1950 INCLUDE 1960-1961...1984-1985...1995-1996...2001-2002. THIS YEAR IS THE SECOND PART OF A 2005-2006 CYCLE.

AS WE APPROACH THE UPCOMING HURRICANE SEASON...SEVERAL CORRELATIONS TO THE LA NINA AND ATLANTIC TROPICAL CYCLONE ACTIVITY WILL BE MADE. RECENT STUDIES INDICATE THAT THE LA NINA PHASE OF THE ENSO CYCLE IS TYPICALLY MORE ACTIVE...SLIGHTLY ABOVE NORMAL...THAN THE EL NINO COUNTERPART OF THE ENSO CYCLE. THE COMPARABLE OR ANALOG YEARS PREVIOUSLY MENTIONED AVERAGED 12 NAMED STORMS AND 7 HURRICANES IN THE ATLANTIC BASIN IN THE SECOND SEASON OF THE PHASE. ON AVERAGE IN THE
GULF OF MEXICO IN ANALOG YEARS...3 NAMED STORMS AND 2 HURRICANES TYPICALLY DEVELOP. WHILE THESE ARE STATISTICAL AVERAGES...THEY DO NOT FULLY REVEAL WHAT KIND OF ACTIVITY CAN BE EXPECTED IN THE UPCOMING SEASON NOR INDICATE AREAS OF HIGHER CHANCES OF LANDFALLING HURRICANES.

HISTORICALLY...SOUTHEAST LOUISIANA AND COASTAL MISSISSIPPI HAD SEVERAL TROPICAL STORMS AND HURRICANES OCCUR IN THE COMPARABLE YEARS. IN 1960...HURRICANE ETHEL HIT LOUISIANA AND MISSISSIPPI. IN 1985...HURRICANE ELENA STRUCK THE MISSISSIPPI COAST AND HURRICANE JUAN MEANDERED OVER SOUTH LOUISIANA FOR SEVERAL DAYS. THE 1995-1996 SEASONS HAD NO LANDFALLS IN LOUISIANA OR MISSISSIPPI. IN 2001... TROPICAL STORM ALLISON AFFECTED SOUTHEAST TEXAS...LOUISIANA AND MISSISSIPPI. IN 2002...AN ACTIVE SEASON SAW TROPICAL STORMS BERTHA...HANNA AND ISIDORE MAKE LANDFALL IN THE CENTRAL GULF STATES ALONG WITH HURRICANE LILI INTO SOUTH-CENTRAL LOUISIANA. FINALLY....THE 2005 SEASON SAW 10 NAMED STORMS AND 6 HURRICANES IN THE GULF OF MEXICO WITH HURRICANES CINDY...KATRINA AND RITA MAKING HISTORICAL LANDFALLS ON LOUISIANA AND MISSISSIPPI SHORES.

And 3 out of 4 had landfalls in TX.
