NEW ORLEANS — Weather forecasters warned residents along Louisiana’s coast to rush preparations Saturday in anticipation of an intensifying Hurricane Ida, which is expected to bring winds as high as 140 mph (225 kph) when it slams Sunday ashore.
Authorities called a combination of voluntary and mandatory evacuations for cities and communities across the region. In New Orleans, the mayor ordered a mandatory evacuation for areas outside the city’s levee system and a voluntary evacuation for residents inside the levee system. But since the storm quickly escalated in intensity, Mayor LaToya Cantrell said it was not possible to order a mandatory evacuation for the entire city, which would require using all lanes of some highways to leave the city.
“If you plan to evacuate, do so now,” said a mid-morning advisory from the city. Traffic was heavy on westbound routes out of town early Saturday, and gas stations were busy. The storm is expected to make landfall on the exact date Hurricane Katrina devastated a large swath of the Gulf Coast 16 years earlier. But whereas Katrina was a Category 3 when it made landfall southwest of New Orleans, Ida is expected to reach an extremely dangerous Category 4 hurricane, with top winds of 140 mph (225 kph) before making likely landfall west of New Orleans late Sunday.
“Today is it,” Jamie Rhome, acting deputy director of the U.S. National Hurricane Center in Miami, said Saturday. “If you’re in coastal Louisiana and Mississippi, you really, really have to get going because today is it in terms of protecting life and property.” Ida intensified Friday rapidly from a tropical storm to a hurricane with top winds of 80 mph (128 kph) as it crossed western Cuba.
Late Saturday morning, Ida was centered 435 miles (710 kilometers) southeast of Houma, a city on Louisiana’s coast. It was traveling northwest at 16 mph (26 kph), forecasters said. Its maximum sustained winds were 85 mph (140kph). The wind speed in the late morning forecast had not picked up from an earlier advisory from the National Hurricane Center. However, forecasters still expected it to reach Category 4 strength before landfall on the central Louisiana coast.
In New Orleans, city officials said residents need to be prepared for prolonged power outages and asked elderly residents to consider evacuating. Collin Arnold, the city’s emergency management director, said the city could be under high winds for about 10 hours. Earlier Friday, Cantrell called for a mandatory evacuation for residents outside the city’s levee protections — a relatively tiny sliver of the city’s population.
Ida would be the latest test of New Orleans’ aging street drainage system. In a statement Friday, the city outlined steps to ensure that pumps were working and power sources to those pumps were ready. But the amount of rain could be enough to overwhelm even a fully functional system.
“We want to be clear that with the amount of rain now forecasted, approximately 10 inches throughout the event, it is likely that we will experience flooding,” the city said in a late Friday statement.
Some ordinarily bustling businesses were closed Saturday. One popular breakfast spot was locked up tight with sandbags against the door to guard against flash floods.
With the storm’s forward speed slowing down and the intensity picking up, the storm surge may overtop some levees that protect parts of New Orleans on the west bank of the Mississippi River, said Heath Jones, emergency manager of the Army Corps Engineers’ New Orleans District. However, he said they are designed to be overtopped and have protections to prevent more damage. There does not appear to be any danger of storm surge coming over the levees that protect the city’s east bank, which makes up most of the town, he said.
Across the region, residents filled sandbags, got gasoline for cars and generators, and stocked up on food. Capt. Ross Eichorn, a fishing guide on the coast about 70 miles (112 kilometers) southwest of New Orleans, said he fears warm Gulf waters will “make a monster” out of Ida.
“With a direct hit, ain’t no telling what’s going to be left — if anything,” Eichorn said. A hurricane warning was issued for most of the Louisiana coast from Intracoastal City to the mouth of the Pearl River, including metropolitan New Orleans. A tropical storm warning was extended to the Alabama-Florida line.
President Joe Biden approved a federal emergency declaration for Louisiana ahead of the storm. Additionally, the hurricane center said a new tropical depression formed early Saturday. It was centered 800 miles (1,285 kilometers) east of the Leeward Islands. It was expected to remain over the open Atlantic Ocean and posed no hazards to land.
