Tropical Storm Zeta is spinning across the U.S. South after walloping New Orleans, blacking out 1.9 million homes and businesses and leaving a trail of wreckage from Louisiana to North Carolina.

Hurricane Zeta is strengthening as it spins across the Gulf of Mexico, threatening to slam into New Orleans in the evening Oct. 28 as a Category 2 storm capable of uprooting trees and causing massive power outages.

Storm-weary Louisiana is once again under a hurricane warning, with Zeta leaving Mexico’s Yucatan Peninsula on a path that could hit New Orleans the night of Oct. 28.

Tropical Storm Zeta gathered strength as it bore down on the Mexican cities of Cozumel and Cancun, where it was forecast to dump heavy rain before turning north to threaten the U.S. Gulf Coast from Louisiana to Mississippi with another direct hit.
