Louisiana Declares Emergency Ahead of Tropical Storm Nicholas

Nicholas reached hurricane strength as it approaches landfall in Texas, bringing flooding rains to Houston and parts of Louisiana still recovering from Hurricane Ida’s blow two weeks ago.

Nicholas was upgraded to a hurricane with winds reaching 75 miles per hour, the National Hurricane Center said in an 11 p.m. New York time advisory. The storm was located about 20 miles (32 kilometers) southeast of Matagorda, Texas, and was expected to reach landfall within hours.

While it will mostly bypass the Gulf of Mexico’s oil and natural gas platforms, it could dump as much as 18 inches (46 centimeters) of rain, posing a threat to coastal refineries and petrochemical facilities. 

Louisiana Declares Emergency Ahead of Tropical Storm Nicholas

“Houston is in the crosshairs,” said Steve Silver, a senior meteorologist with Maxar, noting that precipitation poses a bigger threat than wind. Nicholas will be “a significant rainfall event.” 

Louisiana Governor John Bel Edwards declared a state of emergency and Texas Governor Greg Abbott ordered emergency crews to get ready for the storm. A hurricane warning stretches from Port O’Connor to Freeport, Texas, and the heaviest rain will likely fall from Monday to Wednesday, according to the Weather Prediction Center. The storm surge could reach five feet at Galveston Bay in Houston. 

The storm’s slow forward advance adds to the flooding risk as it passes over the region. 

“I would call it a serious threat,” said Jim Rouiller, lead meteorologist at the Energy Weather Group. “If it slows up tomorrow, we could have serious trouble.”

Nicholas is the Atlantic’s 14th storm in 2021. Half of the storms so far have hit the U.S., and Ida was the season’s worst, crashing into the Louisiana coastline before devastating New York with rain and floods that killed more than 40 people. On Monday, AIR Worldwide updated its projected losses from Ida, saying the storm probably caused $20 billion to $30 billion in insured losses. Earlier estimates ranged around $18 billion

The latest storm is expected to hit areas of Louisiana still recovering from last year’s Hurricane Laura and is likely to bring heavy rain to areas slammed by Ida, Edwards said. That could also disrupt efforts to restore power. 

Nicholas may also disrupt restoration efforts of Gulf of Mexico oil platforms and pipelines that have remained offline since Ida. Nearly 50% of oil supply is still down in the Gulf and the volume of shut-in output may start growing once again. U.S. Gulf Coast physical crude prices could surge if supplies aren’t returned promptly.

An average Atlantic season produces 14 storms by the time it ends in November, so 2021 is ahead of pace.
