Hurricane Ida has made landfall in southeast Louisiana as a powerful Category 4, where it's bringing life-threatening storm surge, catastrophic winds, and dangerous rainfall flooding.

Ida's center crossed the coast near Port Fourchon, Louisiana, at 11:55 a.m. CDT. Maximum sustained winds were 150 mph, making Ida a high-end Category 4.

Ida has tied two other hurricanes for the strongest landfall on record in the state of Louisiana based on maximum wind speeds. Laura had 150-mph winds when it tracked into southwest Louisiana last year. The other hurricane to make landfall in Louisiana with winds that high was in 1856.

Bands of heavy rain containing strong wind gusts are spreading into the northern Gulf Coast as far east as the Florida Panhandle.

Wind gusts over 120 mph have been clocked at an elevated weather station along the far southeast coast of Louisiana. Storm surge has pushed water levels over 6 feet above normal at Shell Beach, Louisiana, and Waveland, Mississippi.

Serious storm surge flooding has been accompanied by wind gusts over 100 mph in Grand Isle, Louisiana.

Parts of the New Orleans metro area have seen wind gusts top 60 mph.

The National Weather Service has issued an extreme wind warning for far southeast Louisiana until at least 1:30 p.m. CDT. This means winds of 115 to 150 mph are possible in this area.

A hurricane warning is posted from Intracoastal City, Louisiana, eastward to the mouth of the Pearl River, including Lake Pontchartrain, Lake Maurepas, and the New Orleans metro area.

A tropical storm warning is posted from Cameron, Louisiana east to Intracoastal City, Louisiana, and from the Pearl River in Louisiana to the Alabama/Florida border. Tropical storm warnings are also in effect as far inland as northeast Louisiana and central Mississippi.
Forecast Impacts

Storm Surge

Life-threatening storm surge is forecast near and east of where Ida makes landfall. Follow all evacuation orders from local officials if you are in an area vulnerable to storm surge.

A storm surge warning has been issued from the Intracoastal City, Louisiana, to the Alabama/Florida border including Vermilion Bay, Lake Borgne, Lake Pontchartrain, Lake Maurepas and Mobile Bay. This means life-threatening inundation from storm surge is expected in these areas

The following storm surge inundations are possible if the peak surge happens at high tide, according to the National Hurricane Center (NHC).

-Port Fourchon, Louisiana, to the Mouth of the Mississippi River: 12 to 16 feet

-Morgan City, Louisiana, to Port Fourchon, Louisiana: 8 to 12 feet

-Mouth of the Mississippi River to Bay St. Louis, Mississippi, including Lake Borgne: 8 to 12 feet

-Bay St. Louis, Mississippi to Ocean Springs, Mississippi: 6 to 9 feet

-Burns Point, Louisiana, to Morgan City, Louisiana: 5 to 8 feet

-Lake Pontchartrain: 5 to 8 feet

-Ocean Springs, Mississippi, to the border between Mississippi and Alabama: 4 to 7 feet

-Lake Maurepas: 4 to 6 feet

-Intracoastal City, Louisiana, to Burns Point, Louisiana, including Vermilion Bay: 3 to 5 feet

This peak surge will occur within an hour or two of Ida's landfall.

The NHC also notes that overtopping of local levees outside of the hurricane and storm damage risk reduction system is possible where local inundation values may be higher.

Hurricane conditions will spread northward through the hurricane warning area of southeast Louisiana during the day on Sunday.

The NHC said wind damage could be "potentially catastrophic" near where the core of Ida makes landfall in Louisiana.

The worst winds are most likely near the coast between Grand Isle and Morgan City, where wind gusts over 100 mph are possible.

Downed trees, widespread power outages and structural damage will impact a large portion of southeast Louisiana into southwest Mississippi, including parts of the Baton Rouge and New Orleans areas. Power outages in some locations could last for days or even weeks.

Scattered power outages are possible well inland into Monday, possibly as far north as northern Mississippi, southwest Tennessee and northwest Alabama.

Widespread flash flooding, particularly where bands of rain stall for a period of a few hours, is expected near and inland from the northern Gulf Coast. Heavy rain will also lead to river flooding that could linger for several days after the storm.

At least a local flash flood threat will also penetrate inland into the Deep South, Tennessee Valley, Ohio Valley, Central Appalachians, and mid-Atlantic through midweek.

NOAA's Weather Prediction Center is forecasting the following rainfall totals:

-Southeast Louisiana and southern Mississippi: 10 to 18 inches, with isolated 24-inch totals through Monday.

-Coastal Alabama to the western Florida Panhandle: 5 to 10 inches, with locally up 15 inches possible through Tuesday morning.

-Central Mississippi: 4 to 8 inches, with isolated totals up 12 inches possible through Monday night.

-Middle Tennessee Valley to the Ohio Valley, Central Appalachians and mid-Atlantic: 3 to 6 inches, with localized heavier totals Tuesday into Wednesday.

Tornadoes

Isolated tornadoes are frequently a concern with landfalling tropical cyclones.

Some rotating cells in Ida's rainbands may spawn tornadoes from southeast Louisiana into southern Mississippi, southern Alabama and the Florida Panhandle Sunday into Monday. This threat might spread as far north and east as the Tennessee Valley and northern Georgia Monday into Tuesday.

As a reminder, Tropical Storm Fred spawned 29 tornadoes from the South to the Northeast over a week ago.

The fog tucked us in last night, leaving for some surreal driving conditions on the roads. We see the potential for a repeat situation this evening for the valley.
