MIAMI (AP) — The Atlantic hurricane season will likely be a busy one that may spawn as many as 23 named tropical storms, including up to seven major hurricanes, a number that’s not likely to be affected by the Gulf oil spill, the U.S. government said Thursday.

The National Oceanic and Atmospheric Administration predicted that eight to 14 storms would strengthen into hurricanes, with top winds of 74 mph or higher. Three to seven of those could become major storms that reach Category 3 or higher — meaning they bring sustained winds of at least 111 mph.

‘‘If this outlook holds true, this season could be one of the more active on record,’’ NOAA administrator Jane Lubchenco said in a statement. ‘‘The greater likelihood of storms brings an increased risk of a landfall. In short, we urge everyone to be prepared.’’

A hurricane might help break up the oil spill staining the Gulf of Mexico, but the oil won’t affect significantly how tropical storms develop, forecasters said.

The 2010 government forecast is based on the weakening of El Nino. The Pacific Ocean phenomenon created strong wind shear that helped suppress storm development in the Atlantic last season. Record warm water temperatures also will feed storms crossing the Atlantic this year.

Three hurricanes developed out of nine tropical storms in 2009.

None of the hurricanes came ashore in the United States. Hurricane Ida hit Nicaragua as a Category 1 storm in November.

Florida Gov. Charlie Crist urged coastal residents to remember the destruction left in the wake of hurricanes in 2004 and 2005.

‘‘Don’t take anything for granted,’’ Crist said at the annual Florida Governor’s Hurricane Conference in Fort Lauderdale. ‘‘We don’t need to suffer from hurricane amnesia.’’

National Hurricane Center Director Bill Read said Wednesday that his biggest concern for the season is a storm striking Haiti, where hundreds of thousands of people have been living in makeshift camps since the Jan. 12 earthquake. Heavy rains can trigger serious flooding and mudslides in the mountainous Caribbean country, but no evacuation plans exist for displaced communities.

Tropical storms are named when their sustained winds reach 39 mph. The first named storm of the 2010 season will be Alex.

In April, Colorado State University researchers predicted 15 named storms would form this season, with four developing into major hurricanes.

The Atlantic hurricane season begins Tuesday and runs through Nov. 30.
