Nine to 15 tropical storms are expected, with four to eight of those strengthening into hurricanes.
The federal government is predicting a near-normal Atlantic hurricane season in 2012.
Nine to 15 tropical storms are forecast in the initial outlook issued Thursday by the National Oceanic and Atmospheric Administration. Four to eight of those storms may strengthen into hurricanes, and one to three of those could grow into "major" hurricanes of Category 3 or higher, Reuters reported.

The six-month storm season officially begins June 1, but got off to an early start with the formation of Tropical Storm Alberto last Saturday off South Carolina's coast, according to The Associated Press.
Last year marked the sixth consecutive year without a major hurricane making US landfall, according to the AP.

Two current climate factors are expected to limit hurricane development this year, if they persist: strong wind shear, which can tear apart burgeoning hurricanes, and cooler sea-surface temperatures in the far eastern Atlantic, USA Today reported.
"Another potentially competing climate factor would be El Niño, if it develops by late summer to early fall," Gerry Bell, lead seasonal hurricane forecaster at NOAA's Climate Prediction Center, told USA Today.
Earlier this month, two of the biggest private weather forecasting companies, AccuWeather and the Weather Channel, also predicted an average or slightly below-average hurricane season, according to the Washington Post.
Last month, meteorologists at Colorado State University estimated 10 tropical storms, four of which would be hurricanes. Colorado State University meteorologist William Gray was the first scientist to make seasonal hurricane forecasts in the 1980s.
