Hurricane Beryl was moving toward Mexico’s Yucatán Peninsula early Friday as a Category 3 storm, after spending the last week tearing through the eastern Caribbean, where it left islands flattened in its wake. It was expected to make landfall on Friday before emerging in the Gulf of Mexico.

At least eight people have been killed as the storm lashed parts of Grenada, then Jamaica and the Cayman Islands this week. Beryl, which formed as a tropical storm last Friday, grew at one point to a Category 5 hurricane, breaking a record for the earliest such storm in the Atlantic season.

Here are key things to know about the storm:

• Hurricane watches and warnings were in effect across the Yucatán Peninsula on Friday morning, and the storm is not expected to weaken as it approaches land.

• Storm surge could raise water levels by as much as four to six feet.

• Beryl is expected to weaken quickly when it crosses the Yucatán Peninsula and re-intensify when it emerges over the Gulf of Mexico by the end of the day.

• Early Friday morning, the National Weather Service said there was an “increasing risk” that northeastern Mexico and southern Texas would see strong winds, storm surge and heavy rain by the end of the weekend.

The storm has left destruction in its wake.

Beryl made landfall on Monday in Grenada, where officials said about 98 percent of the buildings on Carriacou and Petite Martinique, where 9,000 to 10,000 people live in total, had been damaged or destroyed, including Carriacou’s main health facility. Crops were ravaged, and fallen trees and utility poles littered the streets.

“We have to rebuild from the ground up,” said Dickon Mitchell, prime minister of Grenada.

It then churned along toward Jamaica, where on Wednesday heavy rain and destructive winds left their mark as well. Beryl was the strongest storm to approach the island in over a decade.
