Nicholas dumps rain along Gulf Coast.
HOUSTON (AP) — Tropical Storm Nicholas hit the Texas coast early Tuesday as a hurricane and dumped more than a foot (30.5 centimeters) of rain along the same area swamped by Hurricane Harvey in 2017, drenching storm-battered Louisiana, knocking out power to hundreds of thousands of people and bringing the potential for life-threatening flash floods across the Deep South.
Nicholas made landfall on the eastern part of the Matagorda Peninsula and was soon downgraded to a tropical storm. It was about 15 miles southsouthwest of Houston, Texas, with maximum winds of 60 mph as of 7 a.m. CDT Tuesday, according to the National Hurricane Center in Miami. Nicholas was the 14th named storm of the 2021 Atlantic hurricane season.
Galveston saw nearly 14 inches of rain from Nicholas while Houston reported more than 6 inches of rain — a fraction of what fell during Harvey, which dumped more than 60 inches of rain in southeast Texas over a four-day period.
Nicholas is moving so slowly it will dump several inches of rain as it crawls over Texas and southern Louisiana, meteorologists said. This includes areas already struck by Hurricane Ida and devastated last year by Hurricane Laura. Parts of Louisiana are saturated with nowhere for the extra water to go, so it will flood, said University of Miami hurricane researcher Brian McNoldy.
"It's stuck in a weak steering environment," McNoldy said Tuesday. So while the storm itself may weaken "that won't stop the rain from happening. Whether it's a tropical storm, tropical depression or post-tropical blob, it'll still rain a lot and that's not really good for that area."
The storm was moving northnortheast at 8 mph and the center of Nicholas was expected to move slowly over southeastern Texas on Tuesday and over southwestern Louisiana on Wednesday.
Nicholas, expected to weaken into a tropical depression by Wednesday, could dump up to 20 inches of rain in parts of central and southern Louisiana.
Much of Texas' coastline was under a tropical storm warning that included potential flash floods and urban flooding. Texas Gov. Greg Abbott said authorities placed rescue teams and resources in the Houston area and along the coast.
In Houston, officials worried that heavy rain could inundate streets and flood homes. Authorities deployed high-water rescue vehicles throughout the city and erected barricades at more than 40 locations that tend to flood, Mayor Sylvester Turner said Monday.
"This city is very resilient. We know what we need to do. We know about preparing," said Turner, referencing four major flood events that have hit the Houston area in recent years, including devastating damage from Harvey.
Meteorologist Kent Prochazka of the National Weather Service told The Associated Press early Tuesday that Nicholas' winds downed trees in coastal counties and caused some gas stations to lose awnings.
"Right before it made landfall, it abruptly intensified into a hurricane and as it moved inland, the pressures began to rise with it. The winds have relaxed slightly and now we're getting down into tropical storm force (winds)," he said.
CenterPoint Energy reported that over 450,000 customers were without power as the storm rolled through Houston.
