A Hurricane We Will Remember For A Long Time

| August 29, 2012 @ 7:51 pm

The center of tropical Storm Isaac is approaching Baton Rouge tonight.

Donaldsonville is already in the center, which is certainly less defined, but winds there are ESE at 8 mph. The pressure was 28.87 inches or 978 millibars. Officially, winds are listed at 60 mph.

The center is moving slolwy north northwest.

At Baton Rouge, there is heavy rain with NNE winds at 25 gusting to 39 mph.

Some dry air has worked into the western side of the circulation, drying up the rain on that side of the storm, from Opelousas to New Ibera to Frankin and shortly to Houma.

Still getting northwest winds at 52 gusting to 64 mph at a platform 65 miles south of New Iberia.

At Louis Armstrong New Orleans International Airport, it was raining with overcast skies, winds SSE at 35 gusting to 45 mph. The barometer is reading 29.15 inches of mercury. Rain should begin to diminish in the next couple of hours at the Airport and hopefully soon in the city of New Orleans as well. But this will not be before a record rainfall was set for the date, 5.64 inches. This broke the previous record of 4.50 inches 7 years ago. Wonder what was happening that day?

Interestingly, the Mississippi River flowed backwards last night and this morning, as a storm surge pushed all the way past Baton Rouge.

Numerous flash flood warnings across southeastern Louisiana, southern Mississippi and even Mobile County in Alabama.

In Alabama, there is a tornado warning for Monroe and Wilcox Counties in Southwest Alabama. This for radar indicated tornado near Pine Apple.

This storm is part of a band of scattered storms that extends from Wilcox and Dallas counties through Pike, Barbour and Henry Counties in in Southeast Alabama. This band is weakening, with the exception of the westernmost storm.

The band of showers approaching the I-20 corridor has all but fallen apart.

6-8 inches of rain will follow the slowly decaying low as it moves through Louisiana, Arkansas, Missouri and Illinois into Indiana.
