Isaac Moves Onshore Over Louisiana

29 Aug 2012, 1:03 pm

Isaac moved onshore for the second time earlier this morning, and is slowly starting to weaken. However, heavy rains are a big concern as we go through the next few days from the Gulf Coast to the Ohio Valley.

Isaac as of 2 PM ET

Issac, now over land, is slowly starting to weaken. Winds are still reaching 75 mph, and the storm is finally starting to get a little kick to it, moving to the NW at 6 mph.

You can see the circulation of Isaac sitting just inland from the Gulf of Mexico on the Louisiana coastline via the wind map.

Impacts earlier today

Isaac has made two landfalls within the past 12-24 hours. The first, Tuesday Night near the mouth of the Mississippi, and then one earlier this morning around Port Fourchon.

We have seen high winds and impressive rainfall amounts from Isaac over the past couple days, greatly affecting how people are going about their lives in the Gulf Coast states. Above are some of the more impressive numbers we have found so far.

We’ve had reports of levees being topped in Plaquemines Parish. Areas near Braithwaite, LA are under 12′ of water from the overtopping. Residents are in the progress of being evacuated. We’ll have a picture from that area later in this blog.

We also had a report from Jeff Piotrowski of another levee almost being overtopped or breached in southern Plaquemines Parish. The levees are definitely going to be a concern in southern Louisiana over the next day.


We are looking at the system starting to pick up in speed over the next few days after hanging out over Louisiana for the next day or so. After that we should see the storm turn to the northeast and affect areas such as Illinois and Indiana into the weekend.

Rainfall amounts should be over 10″ in some locations of Louisiana over the next few days. As they system works northward, we expect to see rainfall amounts decrease, but 4″+ are possible from Missouri into Ohio through Monday morning.
