LONDON (ICIS)--Tropical Storm Nicholas is expected to cause “life-threatening” flash floods across the southern US as it approaches Houston, the National Hurricane Center (NHC) said on Tuesday, as hurricane warnings across the region were downgraded.
The storm made landfall in the petrochemicals hub states of Texas and Louisiana on Monday night local time, with maximum sustained windspeeds of 75 miles/hour (120 kilometres/hour), according to the NHC.
As of early Tuesday morning in the US, a hurricane warning in place from Matagorda to Freeport had been downgraded to a tropical storm warning, as have alerts from Freeport to San Luis Pass and south of Matagorda to Port O’Connor.
The NHC also issued a fresh tropical storm warning from Sabine Pass to Cameron, Louisiana, as well as storm surge warnings across Sargent, Sabine Pass and across to Rutherford Beach, Louisiana.
The storm surge warnings could lead to evacuations of those areas, the agency added.
“This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions,” the NHC said.
Nicholas comes 15 days after Hurricane Ida made landfall in Louisiana, causing significant disruption to oil and natural gas production in the US Gulf.
