TULUM, Mexico (AP) — Beryl battered Mexico's Yucatan Peninsula on Friday after hitting near the resort town of Tulum, whipping trees and knocking out power, and officials in Texas urged coastal residents to prepare as the storm moves toward the Gulf of Mexico

Beryl hit Mexico as a Category 2 hurricane but weakened to a tropical storm as it moved across the peninsula. The U.S. National Hurricane Center expects Beryl to regain hurricane strength once it reemerges into the warm waters of the Gulf of Mexico, where it is forecast to head toward northern Mexico near the Texas border, an area soaked by Tropical Storm Alberto just a couple of weeks ago.

Beryl spread destruction in Jamaica, St. Vincent and the Grenadines, and Barbados this week after becoming the earliest storm to develop into a Category 5 hurricane in the Atlantic. Three people have been reported dead in Grenada, three in St. Vincent and the Grenadines, three in Venezuela and two in Jamaica, officials said.

Mexican authorities had moved some tourists and residents out of low-lying areas around the Yucatan Peninsula before landfall, but tens of thousands remained to tough out the strong winds and expected storm surge. Much of the area around Tulum is just a few yards (meters) above sea level.

The city was plunged into darkness when the storm knocked out power as it came ashore. Screeching winds set off car alarms across the town. Wind and rain continued to whip the seaside city and surrounding areas Friday morning. Army brigades roved the streets of the tourist city, clearing fallen trees and power lines.

After seeing Beryl tear through the Caribbean, 37-year-old Luci´a Nagera Balcaza was among those who stocked up on food and hid away in their homes.

"Thank god, we woke up this morning and everything was all right," she said. "The streets are a disaster, but we're out here cleaning up."

Although no dead or wounded have been reported, nearly half of Tulum continued to be without electricity, said Laura Velázquez, national coordinator of Mexican Civil Protection.

In Texas, some counties have already issued voluntary evacuation orders in low-lying areas. Along the Texas coast in Corpus Christi, city officials announced it had distributed 10,000 sand bags in less than two hours on Friday, exhausting its supply.

"This is a determined storm, that is still strong," Texas Lt. Gov. Dan Patrick said.

Patrick has issued a pre-emptive disaster declaration for 39 counties, which allows state and local authorities to start planning and contracting for response.

Nim Kidd, chief of state emergency operations, said oil companies have started moving employees off oil rigs along the coast that may be in the path of the storm.

While many in the Yucatan Peninsula took a deep breath, Jamaica and other islands ravaged by the hurricane were still reeling. As of Friday morning, 55% of Jamaica still without electricity and most of the country was without running water, according to government figures.

Jamaican Prime Minister Andrew Holness promised swift relief for residents affected by Hurricane Beryl after visiting one of the worst-affected areas of the island, the southern parish of St Elizabeth on Thursday afternoon.

"I know some of you are experiencing discomfort and displacement, and I want to assure you that the government will move as quickly as we can to get you the help you need," he said.

The storm's center Friday afternoon was about 60 miles (95 kilometers) northwest of the town Dzilam and moving west-northwest at 15 mph (about 24 kph), Mexicans authorities said. Beryl had maximum sustained winds of 70 mph (115 kph).

Before the storm hit Mexico, official had set up shelters in schools and hotels. When the wind began gusting over Tulum's beaches Thursday, officials on four-wheelers with megaphones rolled along the sand telling people to leave and authorities evacuated beachside hotels. Sea turtle eggs were even moved off beaches threatened by storm surge.

Tourists also took precautions. Lara Marsters, 54, a therapist visiting Tulum from Boise, Idaho, said she had filled up empty water bottles from the tap.

"We're going to hunker down and stay safe," she said.

Earlier in the week, the hurricane 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 and knocked out electricity in Jamaica.

On Union Island, part of St. Vincent and the Grenadines, a man who identified himself as Captain Baga described the storm's impact, including how he had filled two 2,000-gallon (7,570-liter) rubber water tanks in preparation.

"I strapped them down securely on six sides; and I watched the wind lift those tanks and take them away — filled with water," he said Thursday. "I'm a sailor and I never believed wind could do what I saw it do. If anyone (had) ever told me wind could do that, I would have told them they lie!"

The island was littered with debris from homes that looked like they had exploded.
