The hurricane that battered the Louisiana coast, has left billions of dollars in insured losses, according to a Karen Clark & Company flash estimate.

Hurricane Francine soaked Louisiana with 7.33 inches of rain in one day, knocked out electricity to hundreds of thousands of homes and businesses and threatened widespread flooding.

It also sent a potentially deadly storm surge rushing inland along the Gulf Coast, affecting portions of the Mississippi Delta, Alabama, western Georgia and the Florida Panhandle.

The high-resolution KCC US Hurricane Reference Model estimate of $1.5 billion includes the privately insured damage to residential, commercial, and industrial properties and automobiles, as well as business interruption.

It does not include boats, offshore properties, or National Flood Insurance Plan losses.

Hurricane Francine made landfall near Terrebonne Parish as a Category 2 hurricane with 100-mph maximum sustained winds.

But Following landfall, Francine rapidly weakened, eventually becoming a tropical depression while moving northward into Mississippi. The system transitioned to a post-tropical cyclone over central Mississippi.

KCC said: “New Orleans was spared from the highest wind speeds, which would have led to a much higher loss event, but tropical storm winds did affect the entire city.

“Hurricane Francine passed well to the east of Baton Rouge where relatively lower, but still potentially damaging, winds were observed.

“Storm surge levels were not high enough to overtop levees, helping to mitigate the damage. Like the wind impacts, the storm surge was highest along and to the east of Francine’s track.

“Terrebonne, Lafourche, and Plaquemines Parishes experienced storm surge heights of over 4 feet along their coastline and among their numerous lakes and wetlands.

“The coastal areas of Mississippi, including Biloxi and Gulfport, experienced similarly high storm surge levels as Francine generated strong onshore winds in this area even after making landfall.

“Surge even funnelled up the Mobile Bay in Alabama and brought two to three feet of surge to Mobile, Alabama and other areas surrounding the Mobile and Tensaw Rivers.”
