Louisiana communities battered by Hurricane Ida face the possibility of weeks without power in the stifling, late summer heat as they begin the task of clearing debris and repairing damage from the storm.
Ida ravaged the region’s power grid, leaving the entire city of New Orleans and hundreds of thousands of other Louisiana residents in the dark with no clear timeline on when power would return.
Some areas outside New Orleans also suffered major flooding and structural damage.
“There are certainly more questions than answers. 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,” Louisiana governor John Bel Edwards told a news conference.
“But what I can tell you is we are going to work hard every day to deliver as much assistance as we can.”
President Joe Biden met virtually with Mr Edwards and Mississippi governor Tate Reeves, along with mayors from cities and parishes most impacted by Hurricane Ida, to receive an update on the storm’s impacts and to discuss how the federal government can provide assistance.
“We are closely coordinating with state and local officials every step of the way,” Mr Biden said.
The storm was blamed for at least four deaths in Louisiana and Mississippi, including two people killed on Monday night when seven vehicles plunged into a 20ft-deep hole near Lucedale, Mississippi, where a road had collapsed after torrential rains.
In Slidell, crews searched for a 71-year-old man whose wife said he was attacked by an alligator in Ida’s floodwaters.
She pulled him to the steps of the home and paddled away to get help, but when she returned he was gone, authorities said.
On Monday, rescuers in boats, helicopters and high-water trucks brought more than 670 people in Louisiana trapped by floodwaters to safety.
An additional 20 people were rescued in Mississippi.
Crews planned to go door to door in hard-hit areas to make sure everyone got out safely.
Power crews also rushed into the state.
The governor said 25,000 utility workers were on the ground in Louisiana to help restore electricity, with more on the way.
Still, his office described damage to the power grid as “catastrophic”, and power officials said it could be weeks before electricity is restored in some spots.
More than one million homes and businesses in Louisiana and Mississippi were left without power as Ida pushed through on Sunday with winds that reached 150mph.
The wind speed tied it for the fifth-strongest hurricane ever to hit the mainland.
By late Monday, the storm had been downgraded to a tropical depression with winds of up to 35mph, though forecasters still warned of heavy rain and a flood threat for parts of the Tennessee and Ohio valleys.
The storm was blamed for at least two deaths – a motorist who drowned in New Orleans and a person hit by a falling tree outside Baton Rouge.
The hurricane blew ashore on the 16th anniversary of Katrina, the 2005 storm that breached New Orleans’ levees, devastated the city and was blamed for 1,800 deaths.
This time, New Orleans escaped the catastrophic flooding some had feared.
But city officials still urged people who evacuated to stay away for at least a couple of days because of the lack of power and fuel.
The US Environmental Protection Agency issued emergency fuel waivers for Louisiana and Mississippi, effective immediately, on Monday night, which will end on September 16.
Some places were also dealing with water problems.
Eighteen water systems were out, impacting more than 312,000 people, and an additional 14 systems affecting another 329,000 people were under boil water advisories, Mr Edwards said.
The hurricane twisted and collapsed a giant tower that carries key transmission lines over the Mississippi River to the New Orleans area, causing widespread outages, Entergy and local authorities said.
The power company said more than 2,000 miles of transmission lines were out of service, along with 216 substations.
The tower had survived Katrina.
The storm also flattened utility poles, toppled trees on to power lines and caused transformers to explode.
In Mississippi’s southwestern corner, entire neighbourhoods were surrounded by floodwaters, and many roads were impassable.
Several tornadoes were reported, including a suspected twister in Saraland, Alabama, that ripped part of the roof off a motel and flipped an 18-wheeler, injuring the driver, according to the National Weather Service.
