Tropical Storm Nicholas headed toward the Texas coast Monday, 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.
In a special advisory late Sunday, forecasters said the center of Nicholas had reformed, and the system strengthened. It had maximum sustained winds of 50 mph (85 kph) and was moving north-northwest at 12 mph (19 kph). It was located off the coast of northeastern Mexico, and was on a forecast track to pass near the South Texas coast later Monday, then move onshore along the coast of south or central Texas by Monday evening.
Nicholas over several days is expected to produce total rainfall of up to 10 inches (25 centimeters) in Texas and southwest Louisiana, with isolated maximum amounts of 20 inches (50 centimeters), across portions of coastal Texas beginning Sunday night through midweek.
Texas Gov. Greg Abbott said the state has placed rescue teams and resources in the Houston area and along the Texas Gulf Coast.
“This is a storm that could leave heavy rain, as well as wind and probably flooding, in various different regions along the Gulf Coast. We urge you to listen to local weather alerts, heed local warnings,” Abbot said in a video message.
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.
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, paralyzed 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 percent of the state — remained without power on Sunday morning, according to the Louisiana Public Service Commission.
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 Sept. 12: 2005, 2011, 2012 and 2020.
