PENSACOLA, Fla. (AP) - The U.S. government is set to update its outlook for the Atlantic hurricane season.

In May, the National Oceanic and Atmospheric Administration predicted that this could be the busiest hurricane season since 2005, when Katrina and Rita ripped along the same part of the Gulf Coast now coping with one of the world's worst oil spills.

NOAA scientists previously said they expected as many as 23 named tropical storms, including up to seven major hurricanes. They will update their forecast Thursday.

So far, three named storms have developed. Hurricane Alex made landfall June 30 in northern Mexico. Tropical Storm Bonnie forced crews drilling a relief well in the Gulf of Mexico to evacuate last week.

Tropical Storm Colin dissipated Tuesday over the open Atlantic.
