The Gulf Coast of Texas and Louisiana was bracing on Monday for the arrival of Tropical Storm Nicholas, which was expected to batter the region with life-threatening storm surge, flash flooding and gusty winds.
The storm, carrying winds of 104 kph, was headed northward at 115 km south of Port O’Connor, Texas, the National Hurricane Center (NHC) said in a Monday afternoon bulletin.
It was forecast to make landfall along the southern or central coast of Texas late on Monday evening.
The National Weather Service issued storm surge, flood and tropical storm warnings and watches that were in effect until at least Tuesday for the area that reached from the southern tip of Texas across the state’s Gulf coast and into the Louisiana.
“This is a life-threatening situation,” the NHC said.”Persons located within these areas should take all necessary actions to protect life and property from rising water.”
Nicholas is the second storm in as many weeks to threaten the US Gulf Coast.
Hurricane Ida wreaked havoc in late August, killing more than two dozen people and as it devastated communities in Louisiana near New Orleans.
“We want to make sure that no one is caught off guard by this storm,” Louisiana Governor John Bel Edwards said during news briefing on Monday afternoon. “Heavy rainfall will be the primary concern.”
Edwards warned that drainage systems still clogged with debris from Ida and other recent storms may not be able to handle the expected deluge of rainwater, causing flash flooding.
Teams of rescue workers with high water vehicles and boats were prepared to respond to people trapped by flooding across southern Louisiana, Edwards said.
Nicholas could also knock out electricity and hamper restoration efforts as more than 119 000 homes and businesses remain without power from Ida, he said.
Houston Mayor Sylvester Turner urged the city’s 2.3 million residents to stay at home starting on Monday evening.
Parts of the city were expected to get 20 cm or even more rain, according to the forecast.
“Take things seriously and prepare,” he said during a news conference. “This is primarily a rain event and we don’t know how much rain we will be getting.”
Houston, the fourth most populous city in the United States,was devastated in 2017 when Harvey, a Category 4 hurricane, slammed Southwest Texas, dropping up to 40 inches of rain in some sections and killing more than 100 people.
As of Monday afternoon, heavy rains fell for about three hours in Houston, where winds were light.
Houston Independent School District canceled classes for Tuesday, while dozens of districts in Texas shut down Monday.
