According to the weather service, an average hurricane season produces 12 named storms.
Meanwhile, Katia strengthened into a hurricane in the southwestern Gulf of Mexico.
All eyes are on Hurricane Irma as it moves toward Florida, but it's not alone.
Irma, a category five hurricane, is expected to have passed over the Caribbean by Friday, however Hurricane Jose is expected to follow a similar path when it arrives over the weekend. However, the hurricane is forecast to turn southwestward and approach the coast within the warning area late Friday or early Saturday.
Jose is moving toward the west-northwest near 17 miles per hour (28 km/h) and this general motion is expected to continue over the next couple of days. Storms of Category 3 and above are defined as major hurricanes.
Irma hit several Caribbean islands on Wednesday, including Barbuda, St. Martin, Anguilla, and St. Barts. The U.S. National Hurricane Center says the storm is stationary with little overall motion expected though late Thursday. The storm is 45 miles east of Tampico, Mexico and could become a Cat.1 hurricane before going ashore.
Jose, like Katia, is a Category 1 hurricane with 75 miles per hour winds.
If the storm tracks over the beleaguered islands of the northern Lesser Antilles, they could face destructive winds for the second time in four days and up to 10 inches of rainfall.
CNN's Leyla Santiago, in the capital of San Juan, said there were already power outages as strong winds lashed the island and the center of the storm moved just off the northeast coast.
Katia is anticipated to pass over Mexico, dumping heavy rain over the states of Veracruz, Tamaulipas and Puebla.
