MIAMI—A strengthening Tropical Storm Zeta is expected to become a hurricane Monday as it heads toward the eastern end of Mexico’s resort-dotted Yucatan Peninsula and then likely move on for a possible landfall on the central U.S. Gulf Coast at midweek.
Zeta on Sunday became the earliest ever 27th named storm of the Atlantic season. The system was centered about 175 miles southeast of Cozumel island Monday morning, the U.S. National Hurricane Center said. It had maximum sustained winds of 70 mph.
