Tropical Storm Nicholas headed toward the Texas coast Sunday night, is threatening to bring heavy rain and floods to coastal areas of Texas, Mexico and storm-battered Louisiana.
Forecasters at the National Hurricane Center in Miami said a hurricane watch was issued for the central portion of the Texas coast with much of the state's coastline now under a tropical storm warning. Nicholas is expected to approach the middle Texas coast late Monday and could bring heavy rain that could cause flash floods and urban flooding.
Nicholas over several days is expected to produce total rainfall of up to 25 centimeters in Texas and southwest Louisiana, with isolated maximum amounts of 50 centimeters, across portions of coastal Texas beginning Sunday night through midweek.
Texas Gov. Greg Abbott placed rescue teams and emergency medical groups on standby along the length of the Texas Gulf Coast.
“We will continue to closely monitor this storm and take all necessary precautions to keep Texans safe,” Abbott said in a statement. “I encourage Texans to follow the guidance and warnings of their local officials and be mindful of potential heavy rain and flooding.”
Louisiana Gov. John Bel Edwards on Sunday night declared a state of emergency ahead of the storm's arrival in a state still recovering from Hurricane Ida and last year's Hurricane Laura and historic flooding.
“The most severe threat to Louisiana is in the southwest portion of the state, where recovery from Hurricane Laura and the May flooding is ongoing. In this area heavy rain and flash flooding are possible. However, it is also likely that all of south Louisiana will see heavy rain this week, including areas recently affected by Hurricane Ida," Edwards said.
At 5:30 AM IST, the centre of the storm was forecasted to pass near or just offshore the coasts of northeastern Mexico and South Texas on Monday, and hit south or central Texas on Monday night or early Tuesday. Its maximum sustained winds were clocked at 40 mph (65 kph) and it was moving north-northwest at 12 mph (19 kph). Gradual strengthening is possible until it reaches the coast Monday night or early Tuesday.
The storm was expected to bring the heaviest rainfall west of where Hurricane Ida slammed into Louisiana two weeks ago. Although forecasters did not expect Louisiana to suffer from strong winds again, meteorologist Bob Henson at Yale Climate Connections predicted rainfall could still plague places where the hurricane toppled homes, paralysed electrical and water infrastructure and left at least 26 people dead.
"There could be several inches of rain across southeast Louisiana, where Ida struck,” Henson said in an email.
Across Louisiana, 140,198 customers -- or about 6.3% of the state -- remained without power on Sunday morning, according to the Louisiana Public Service Commission.
The storm is projected to move slowly up the coastland which could dump torrential amounts of rain over several days, said meteorologist Donald Jones of the National Weather Service in Lake Charles, Louisiana.
“Heavy rain, flash flooding appears to be the biggest threat across our region,” he said.
While Lake Charles received minimal impact from Ida, the city saw multiple wallops from Hurricane Laura and Hurricane Delta in 2020, a winter storm in February as well as historic flooding this spring.
“We are still a very battered city,” Lake Charles Mayor Nic Hunter said.
He said the city is taking the threat of the storm seriously, as it does all tropical systems.
“Hope and prayer is not a good game plan,” Hunter said.
In Cameron Parish in coastal Louisiana, Scott Tranhan is still finishing repairs on his home damaged from last year's Hurricane Laura that put about 2 feet of water in his house. He hopes to be finished by Christmas. He said many in his area have moved instead of rebuilding.
“If you get your butt whipped about four times, you are not going to get back up again. You are going to go somewhere else,” Tranham said.
Colorado State University hurricane researcher Phil Klotzbach said via Twitter that Nicholas is the 14th named storm of 2021 Atlantic hurricane season. Only 4 other years since 1966 have had 14 or more named storms by September 12: 2005, 2011, 2012 and 2020.
