Tropical Storm Edouard expected to inundate parts of Texas and Louisiana

Tropical Storm Edouard headed toward the US Gulf coast early on Tuesday and was expected to gain strength before bringing potentially heavy rains and flooding into parts of Texas and Louisiana.

The storm was upgraded on Monday night from a tropical depression, and forecasters with the National Hurricane Center (NHC) expect it will make landfall in Texas later on Tuesday.

Early on Tuesday, the storm was about 65 miles (100km) south-south-east of Cameron, Louisiana, and 90 miles south-east of Port Arthur, Texas, with maximum sustained winds of 40mph (65km/h) while moving west-north-west at 8mph.

Texas’s governor, Greg Abbott, said the biggest problem expected from the storm was flooding. Forecasters are anticipating 3-6 inches (7-15cm) of rain in the greater Houston area, with some areas of the state’s upper coast getting up to 9in. More than 4in per hour could fall and will probably cause flash flooding in low-lying and urban areas, according to the National Hurricane Center (NHC).

“This is our first big storm of the season, and I’ll tell you, Texas is prepared,” Orlando Alanis of the Texas division of emergency management said during a news conference.

Crews worked on Monday to clear dry vegetation that could ignite from a lightning strike and cause fast-spreading fires, Abbott said.

Meanwhile, the remnants of Tropical Storm Dolly brought rain and thunderstorms to parts of Haiti and the Dominican Republic, the Turks and Caicos, and the Bahamas, the NHC said.

In the Pacific Ocean on Monday evening, Tropical Storm Lowell was about 630 miles south-east of Hilo, Hawaii, with maximum sustained winds of 70mph while moving west at 10mph. Forecasters said Lowell could rapidly intensify and become a major hurricane by Wednesday.

Also in the Pacific, Tropical Storm Marie formed early Tuesday well offshore of south-west Mexico and was not threatening land, the center said. The storm was about 470 miles south-west of Manzanillo with maximum sustained winds of 45mph and was moving north-west. Marie was expected to become a hurricane in the coming days.

Elsewhere in the Pacific, Karina became a hurricane on Sunday, fueled by warm waters far from any shore, and strengthened on Monday into a powerful category 4 storm. But it did not threaten land, forecasters said.

On Tuesday morning, Hurricane Karina remained a category 4 hurricane and was centered 1,210 miles west-south-west of the southern tip of the Baja California peninsula of Mexico with maximum sustained winds of 140mph while moving west-north-west at 10mph, the NHC said.
