MIAMI —

The U.S. National Hurricane Center said on Thursday that Tropical Storm Aletta has formed in the Pacific Ocean off Mexico’s coast.

Aletta, was located about 190 miles from Manzanillo and had maximum sustained winds of 40 mph, was forecast to head away from land and dissipate by the weekend.

In the Atlantic Ocean, Hurricane Beryl weakened over open water near Mexico's Yucatan Peninsula Thursday, going from the earliest Category 5 hurricane in the Atlantic to Category 2 by afternoon.

Beryl was expected to bring heavy rain and moderate winds to Mexico's Caribbean coast, before crossing Yucatan and restrengthening in the Gulf of Mexico to make a second strike on northeast Mexico.

Over the past days, Beryl has damaged or destroyed 95% of homes on a pair of islands in St. Vincent and the Grenadines, jumbled fishing boats in Barbados and ripped off roofs in Jamaica before rumbling past the Cayman Islands early Thursday.
