Colorado State University researchers have released the 2007 Atlantic hurricane forecast for September and October. Phillip J. Klotzbach and William M. Gray with assistance from William Thorson have concluded that the September-only forecast predicts five named storms, two major hurricanes, and a net tropical cyclone activity (NTC) of 80, which is above average.
The research team has predicted five named storms, two hurricanes, one major hurricane, and NTC activity of 42, which is also above average. The team reports that climatologically, September is the most active month of the hurricane season, but they have kept the September monthly forecast the same as was predicted in early August.
According to the Colorado State University Tropical Meteorology Project, forecasts are based on a statistical methodology derived from 55 years of past global reanalysis data and a separate study of prior analog years which have had similar global atmospheric and oceanic precursor circulation features.
