The National Hurricane Center says heavy rainfall and a flash flooding threat continue to spread inland in Mississippi.
Two people have been killed and 10 injured in a road collapse on a Mississippi highway, likely triggered by heavy rains unleashed by Hurricane Ida, officials said.
Three people among those injured were in critical condition, the Mississippi Highway Patrol said on Tuesday.
“We’ve had a lot of rain with Ida, torrential,” Mississippi Highway Patrol officer Calvin Robertson said. “Part of the highway just washed out.”
Seven vehicles plunged into a deep ditch that resulted from the highway collapse, local media reported.
Ida, one of the most powerful hurricanes ever to hit the US Gulf Coast, had weakened to a tropical depression by late Monday as it churned over Mississippi, where the system brought heavy rains overnight.
The storm, which deluged Louisiana with rain and killed at least two people in the state, caused widespread power outages across Louisiana, Mississippi and Alabama, and prompted rescue operations in flooded communities around New Orleans.
By early Tuesday, more than one million customers remained without power in Louisiana, according to PowerOutage, which gathers data from US utility companies.
Residents in the hardest-hit areas could experience power outages for weeks, utility company Entergy said on Monday. Many water systems in the state were also out. Officials in Jefferson Parish in the New Orleans metropolitan area asked residents to conserve water to prevent sewage system backups.
“I can’t tell you when the power is going to be restored. I can’t tell you when all the debris is going to be cleaned up and repairs made,” Governor John Bel Edwards said Monday. “But what I can tell you is we are going to work hard every day to deliver as much assistance as we can.”
Widespread flooding and power outages also slowed efforts on Tuesday by energy firms to assess damages at oil production facilities, ports and refineries.
Late on Monday, the St Tammany Parish Sheriff’s Office said that it is investigating the possible death of a 71-year-old man. His wife told police the man was likely killed by an alligator while walking in floodwaters. The victim has so far not been found and the incident remains under investigation.
Climate change is driving deadly and disastrous weather across the globe, including stronger and more damaging hurricanes.
Ida made landfall on Sunday as a Category 4 hurricane, 16 years to the day after Hurricane Katrina, evoking memories of a disaster that killed more than 1,800 people in 2005 and devastated New Orleans.
But a $14.5bn system of levees, flood gates and pumps designed in the wake of Katrina’s devastation largely worked as designed during Ida, officials said, sparing New Orleans from the catastrophic flooding that devastated the area 16 years ago.
The state’s healthcare systems also appeared to have largely escaped catastrophic damage at a time when Louisiana is reeling from a resurgence of COVID-19 infections that has strained hospitals.
