Tropical Storm Helene threatens Florida, placing most of the state on high alert as it is one of the strongest storms to make landfall in the United States in over a year, according to CNN.

While the storm's track and intensity are likely to change some before it reaches land, NHC forecasters said one factor seems unavoidable: its size.

Helene officially strengthened into a hurricane Wednesday, the National Hurricane Center said. Here's what we know about its forecast in Mexico.

Tropical Storm Helene promised to become a hurricane on Wednesday as it rapidly intensified in the eastern Gulf of Mexico, threatening to bring life-threatening storm surge to Florida within the next two days.

Forecasters say they expect Tropical Storm Helene in the Caribbean Sea to strengthen rapidly and become a hurricane as it moves north across the Gulf of Mexico on Wednesday toward the U.S. The Nationa

Another storm system is taking aim at Florida, this time possibly the Panhandle with storm effects all along the Gulf Coast. Tropical Storm Helene, soon to be a hurricane, is sweeping up from the Caribbean Sea into extremely warm waters that are fuel for tropical cyclones.
