Ida Expected To Make Landfall As Category 4 Hurricane In US

People were evacuating high-risk areas and lining up to buy supplies Friday as Louisiana braced for Hurricane Ida, which was expected to strengthen to an "extremely dangerous" Category 4 hurricane when it hits the southern United States this weekend.

Forecasters warned of surging seas and flooding that could spill over levees as the storm was passing over western Cuba, packing maximum sustained winds near 80 miles (130 kilometers) per hour.

"The time to act is NOW. Hurricane Ida is now forecast to make landfall as a category 4 hurricane," the US National Weather Service urged in a tweet, after the National Hurricane Center (NHC) branded the storm "extremely dangerous."

That level is the second-highest on the Saffir-Simpson hurricane wind scale, with a minimum speed of 130 miles per hour.

The NHC forecast a storm surge of up to six feet above normal tide levels on Cuba's Isle of Youth and warned Friday of expected "life-threatening heavy rains, flash flooding and mudslides" on Jamaica and the Cayman Islands.

Officials have already ordered mandatory evacuations in parts of New Orleans -- which was devastated 16 years ago this month by Hurricane Katrina -- and flood-prone coastal towns on Louisiana's coast such as Grand Isle.

"People are packing and leaving right now," Scooter Resweber, police chief in Grand Isle, told nola.com. "We know this is going to be a big one."

'Potentially devastating'

Louisiana is frequently hit by major storms. New Orleans remains traumatized from Katrina in 2005, which flooded 80 percent of the city and killed more than 1,800 people.

"Now is the time for Louisianans to get prepared," tweeted the state's governor John Bel Edwards, calling on residents to "make sure you and your family are ready for whatever comes."

"Potentially devastating wind damage could occur where the core of Ida moves onshore," the NHC added, noting the storm is likely to produce heavy rainfall and "considerable" flooding from southeast Louisiana to coastal Mississippi and Alabama.

Last week, a rare tropical storm struck the US northeastern seaboard, knocking out power to thousands of Americans, uprooting trees and bringing record rainfall.

Henri missed New York City by several miles but still forced the halt of a star-studded Central Park concert billed as a "homecoming" for a metropolis hard-hit by the pandemic.

Scientists have warned of a rise in the number of powerful cyclones as the ocean surface warms due to climate change, posing an increasing threat to the world's coastal communities.
