This September may come with four hurricanes, including two that will become major storms, according to a report co-authored by Colorado State University researcher Philip J. Klotzbach and his former mentor, professor emeritus William M. Gray.

“Well above-average activity has occurred so far during the 2008 hurricane season,” the report said. “We expect a very active September.”

With another three months of the official hurricane season left to run, this could be a very stormy period. They did not update their forecast for the full season on Tuesday.

Ike and Josephine are two of the mentioned storms having formed in the first days of September. Ike is forecast to strengthen into a hurricane as early as Wednesday. As far as Josephine is concerned, it is still too early to tell where it will go or how strong it will get.

Hanna reached hurricane strength on Monday but turned back into a tropical storm on Tuesday.

Three other Atlantic hurricanes have been recorded so far this season: Bertha and Dolly in July and Gustav in August.

Seven storms have been observed so far this season, including Hurricane Fay, which became the first storm in recorded history to make landfall in Florida four times, and Hurricane Gustav, which made landfall as a Category 4 storm in Cuba on August 30, and as a Category 3 storm in Louisiana on September 1.

Atlantic storm seasons start on June 1st and end November 30 and usually peak on September 10.
