The forecast team at Colorado State University, including Dr. William Gray, expect an above-average end to the hurricane season.

The Atlantic Basin -- which includes the Atlantic Ocean, Caribbean Sea and Gulf of Mexico -- has produced 13 named storms, 4 hurricanes and 2 major hurricanes so far this season. The average for an entire hurricane season is about 10 named storms, 6 hurricanes and 2 major hurricanes.

Dr. Gray's group expects 4 additional named storms to form in the months of October and November 2007. Of those 4 storms, 2 are predicted to reach hurricane intensity.

While meteorologists say it's impossible to predict where these storms may go, the La Nina phenomenon in the Pacific Ocean is expected to reduce vertical wind shear through the end of this hurricane season. Strong vertical wind shear disrupts hurricane formation.
