Isaac’s Remnants are Still Kicking!

Posted on: 1:42 pm, September 4, 2012, by Jason Simpson

Isaac made landfall on Louisiana’s Coast last Tuesday night (and slowly continued to move inland on Wednesday morning), and over the past seven days, it has made it from Plaquemines Parish to the Ohio River Valley creating all kinds of havoc along the way. Numerous tornadoes occurred over Mississippi, Southwest Alabama, and a few others were scattered as far north as Illinois and Missouri.

Sunday’s storms in the Tennessee Valley were one of Isaac’s lingering effects; today’s clouds and showers are also thanks to Isaac.

Last night, heavy storms over Central and South Alabama produced flash flooding a widespread wind damage; Dallas County was one of the hardest hit spots in the entire state. Over 9 inches (9.64″ to be exact) of rain have fallen in Selma since last night, and there is a lot of flash flooding going on down in the Central and South sections of the state.

Here’s the estimated storm total rainfall from the Birmingham NEXRAD at the Shelby County Airport:

A few heavy showers and storms are still possible even in the Tennessee Valley through early evening, but we don’t expect widespread flooding rain or severe weather.

Isaac may have another trick up his sleeve before all is said and done! This mass of clouds, showers and storms that seems somewhat disorganized around the South today could spin up an area of low pressure in the northeastern Gulf of Mexico by Friday. Here’s the NAM model’s forecast map showing what will be Hurricane Leslie off to the right, but the little yellow circle shows where we might have the development of a new tropical depression soon. Odds are, this will not develop into a major storm. There are some general ideas here that suggest it will not have a major impact on Alabama’s Gulf Coast (or for places like Destin or Panama City) this weekend. We will be looking at it closely, and if there’s a change, we’ll let you know!
