Tropical Storm Edouard Approaches Gulf Coast

Tropical Storm Edouard formed in the Gulf of Mexico on Monday and is expected to strengthen before bringing potentially heavy rains and flooding to parts of Texas and Louisiana, according to the National Hurricane Center (NHC). The storm was upgraded from a tropical depression on Monday night, and forecasters expect it to make landfall in Texas on Tuesday.

Early Tuesday, the storm was located about 65 miles south-southeast of Cameron, Louisiana, and 90 miles southeast of Port Arthur, Texas, with maximum sustained winds of 40 mph (65 km/h) while moving west-northwest at 8 mph (13 km/h). Some reports placed the storm slightly farther offshore, at 85 miles southeast of Cameron and 115 miles southeast of Port Arthur, moving west-northwest at 7 mph. The NHC warned that Edouard could approach hurricane strength before reaching the northwest Gulf Coast.

Flooding and Rain Forecast

Texas Governor Greg Abbott said the biggest problem expected from the storm is flooding. Forecasters are anticipating 3-6 inches of rain in the greater Houston area, with some areas of the state's upper coast receiving up to 9 inches. The National Hurricane Center warned that more than 4 inches per hour could fall, likely causing flash flooding in low-lying and urban areas.

Abbott told a Monday press conference: "The biggest problem we expect with the storm at this moment in time is flooding." He added that local rainfall could reach 10-15 inches, with some areas seeing 3 or 4 inches per hour. AccuWeather reported that rain would sweep into Houston by midday Tuesday, with 2-8 inches expected in the city and along the upper Texas coast, and as much as 12 inches in areas east of Houston. In some Gulf Coast areas, winds could reach up to 60 mph.

The NHC warned of flash flooding from the Upper Texas coast into east-central Texas and southwest Louisiana on Tuesday and Wednesday, particularly in urban centers. A storm surge warning is in effect for the coast from High Island to the Vermilion/Cameron Parish Line, according to the agency.

Preparedness and Safety Warnings

Abbott said Texas was prepared to deploy emergency resources, including rescue aircraft, high water vehicles, and swift water rescue boats. "It's so incredibly important for anybody in any region of the state, but especially in Harris County, to avoid driving into what appears to be waters on the roadway," he said. "Too often we see people get swept away or have their cars washed away, especially in the Harris County area because of rising waters."

Orlando Alanis of the Texas Division of Emergency Management said during a news conference: "This is our first big storm of the season, and I'll tell you, Texas is prepared."

Crews worked Monday to clear dry vegetation that could ignite from a lightning strike and cause fast-spreading fires, Abbott said. "We are concerned about additional fires being caused by the storm coming in," he added.

Keith Stephens, a spokesperson for Houston's CenterPoint Energy, warned that some power lines may be brought down in the storm. Pablo Vegas, CEO of the Electric Reliability Council of Texas, said there are no restrictions on energy usage amid the storm. The National Weather Service said its tropical storm warning remains in effect until Wednesday morning for Chambers County and surrounding Gulf Coast areas.

Other Atlantic and Pacific Systems

The remnants of Tropical Storm Dolly brought rain and thunderstorms to parts of Haiti and the Dominican Republic, the Turks & Caicos, and the Bahamas, the hurricane center reported.

In the Pacific Ocean on Monday evening, Tropical Storm Lowell was about 630 miles southeast of Hilo, Hawaii, with maximum sustained winds of 70 mph (110 km/h) while moving west at 10 mph. Some reports placed Lowell about 690 miles southeast of Hilo. Forecasters said Lowell could rapidly intensify and become a major hurricane by Wednesday.

Elsewhere in the Pacific, Tropical Storm Marie formed early Tuesday well offshore of southwest Mexico and was not threatening land, according to the NHC. The storm was about 470 miles southwest of Manzanillo, with maximum sustained winds of 45 mph, and was moving northwest.

Hurricane Karina became a hurricane on Sunday, fueled by warm waters far from any shore, and strengthened Monday into a powerful Category 4 storm. It did not threaten land, forecasters said. On Monday evening, Karina was centered about 1,135 miles west-southwest of the southern tip of Mexico's Baja California peninsula, with maximum sustained winds of 130 mph (215 km/h) while moving west-northwest at 9 mph. Some reports on Tuesday morning placed Karina at 1,210 miles west-southwest with winds of 140 mph (220 km/h).
