NOAA's Climate Prediction Center issued its forecast Wednesday.
Forecasters said there is a 70 percent chance that this hurricane season will be below normal.
Forecasters predict six to 11 named storms, with three to six of those storms becoming hurricanes.
They said up to two of the storms could become major hurricanes.

Forecasters said warm El Niño waters in the Pacific will enhance storms there, but will alter the jet stream, helping it dip farther south. The winds from the jet stream will increase wind shear over the Atlantic, making it difficult for storms to form.
El Niño is forecast to grow stronger as the summer wears on.
"A below-normal season doesn't mean we're off the hook. As we've seen before, below-normal seasons can still produce catastrophic impacts to communities," said NOAA Administrator Kathryn Sullivan.
Hurricanes Andrew and Claudette formed and did their damage during El Niño years.
Tropical Storm Ana, which formed earlier this month, is included in the forecast, but forecasters said it should not be seen as an indication of the overall season strength.
Hurricane season runs from June 1 through Nov. 30.
