Tracking the Tropics: Eyewall of Hurricane Ida moving onshore in Louisiana

TAMPA, Fla. (WFLA) — Hurricane Ida is on its final approach toward the Louisiana coastline as it continues to gather strength before it makes landfall Sunday afternoon or evening.

According to the National Hurricane Center, Ida is about 50 miles south of the mouth of the Mississippi River as it moves northwest at 14 miles per hour. The storm has reached max sustained winds of 150 miles per hour with the potential strengthen again before landfall.

"(The NHC) now call for it to have sustained winds of 155 mph at landfall but say it could be even stronger than that," meteorologist Amanda Holly said. "157 mph is needed for a category five. However, damage wise, it won't make too much of a difference."

The NHC said Ida is expected to bring a "life-threatening storm surge, potentially catastrophic wind damage, and flooding rainfall" to the northern parts of the Gulf Coast, with impacts potentially starting Sunday morning.

Rainfall amounts are expected to be between 10 to 18 inches with isolated maximum levels possibly reaching into 24 inches of rain across southeast Louisiana into southern Mississippi, according to the NHC. The water is expected to be at its deepest on the coast near or east of landfall, where larges waves are expected to join the surge.

Ida is expected move well into the inland parts of Louisiana and west Mississippi before possibly making a turn to the northeast Monday.

  • East of Rockefeller Wildlife Refuge Louisiana to the Alabama/Florida border
