From Tulum to Cancun, tourism-dependent communities still soaked by the remnants of Tropical Storm Gamma could bear the brunt of Delta. Delta increased in strength 80 mph, more than doubling from a 60 mph storm at 2 pm EDT Monday to 140 mph at 2 pm EDT Tuesday.

MEXICO CITY – Tropical Storm Delta rapidly strengthened into a hurricane in the Caribbean Monday, aiming to hit Mexico's Yucatan Peninsula potentially as a major storm before continuing on to strike the U.S. Gulf coast later in the week. It continued to break up just north of the Yucatan Peninsula. The hurricane was moving into an area with very warm water and nearly calm high winds that forecasters at the hurricane center called “a very conducive environment for strengthening." The U.S. National Hurricane Center said Monday evening that a hurricane warning was in effect in Mexico, from Tulum to Rio Lagartos, as well as Cozumel. A tropical storm warning is in effect for the Cayman Islands and the Cuban province of Pinar del Rio.
