MIAMI — U.S. government forecasters announced Thursday that they expect three to six major hurricanes from an above-average Atlantic storm season.

No major hurricane has made a U.S. landfall in five years, but the forecasters warned U.S. coastal residents that odds are diminished for a sixth consecutive year without a major landfall.

Up to 18 named tropical storms may develop during the six-month Atlantic hurricane season, which begins June 1, according to forecasters at the National Oceanic and Atmospheric Administration. Six to 10 of those storms could strengthen into hurricanes with top winds of at least 74 mph, the agency said.

Three to six could become major hurricanes.

Last year’s hurricane season was one of the busiest on record with 19 named storms.
