GALVESTON, Texas (AP) — Hurricane Laura is forecast to rapidly power up into a “catastrophic” Category 4 hurricane, even stronger than previously expected, as it churns toward Texas and Louisiana gathering wind and water that swirls over much of the Gulf of Mexico.

Satellite images show that Laura has become “a formidable hurricane” in recent hours, threatening to smash homes and sink entire communities. It has undergone a remarkable intensification, “and there are no signs it will stop soon,” the National Hurricane Center said in a briefing early Wednesday.

Laura’s maximum sustained winds have increased to near 110 mph (175 kph) with higher gusts, forecasters said early Wednesday.

“We are expecting widespread power outages, trees down. Homes and businesses will be damaged,” said Donald Jones, a National Weather Service meteorologist in Lake Charles, Louisiana, which is near the bullseye of Laura’s forecast track.

“I’m telling you, this is going to be a very serious situation,” Jones said.
