Meanwhile, forecasters warned that Hurricane Katia could strengthen in the warm waters of the western Gulf of Mexico into a major hurricane before it makes landfall in the Mexican state of Veracruz, south of flood-ravaged Texas, which is still reeling from mass flooding after Harvey’s landfall less than two weeks ago. And in the eastern Caribbean, Hurricane Jose is threatening to bring fierce winds and a storm surge to the island of Barbuda, where Hurricane Irma damaged 95 percent of the island’s buildings after it hit on Tuesday.
