Hurricane Harvey to bring 'life-threatening' floods to Texas

Washington, Aug 25 : Texas is expected to experience "life-threatening" floods from the heavy rains and storm surge accompanying Hurricane Harvey, the US National Hurricane Centre (NHC) has announced.

At 9 p.m. (local time) on Thursday night, the storm was located 490 km southeast of Corpus Christi, and moving toward the north-northwest at 17 km/h, according to the latest NHC advisory.

Harvey, now a Category 1 storm with maximum sustained winds of 140 km/h, is forecast to make landfall on the middle Texas coast late Friday or early Saturday as a major hurricane (Category 3, 4 or 5).

The advisory expanded the hurricane warning area, which now extends from Port Mansfield northeastward to Sargent, an area that is home to more than 1.4 million people.

A tropical storm warning has been issued for a larger area populated by roughly 12 million people that includes Houston, the fourth-largest city in the US.

Heavy rains could also affect other parts of southern, central and eastern Texas and neighbouring Louisiana.

"Rainfall from Harvey may cause devastating and life-threatening flooding," the NHC said.

Texas Governor Greg Abbott has already declared a state of emergency for 30 counties that lie in the storm's path.
