Lee Blocks Things Up
I want to thank Chris Misun, a good friend of mine, from Moquah Wisconsin, who now lives Meridian Mississippi, for sending in this picture Friday evening before the rain set in. Tropical Storm Lee, a formidable Tropical Storm, developed in the Gulf of Mexico on Friday. It appears that this slow moving storm will bring very heavy rain to the Lower Mississippi Valley and part of the Tennessee and Mississippi River Valleys through the next several days. When Chris sent me this picture, he mentioned that is was just overcast, but they were waiting for the rain because he said they need it bad!
Infrared Satellite of Lee
The infrared satellite image of Tropical Storm Lee shows a decent swirl in the cloud mass over the Gulf of Mexico. As you would expect, he certainly doesn't look like a hurricane, but because of his slightly more organized structure and his slow movement, Lee is going to pack a tremendous flooding punch for folks along the Gulf Coast States.
Lee Tracks Slowly to the Northeast
The track on Lee is slowly to the northeast, which is going to dump a lot of tropical moisture over the Gulf Coast States. The good news is that Lee's winds aren't going to be all that strong because he'll stay at tropical storm strength throughout his life span over the Lower Mississippi Valley.
Major Flooding Due To Lee
I am very worried about the flooding potential as a ridiculous amount of rain looks to fall in spots that had river flooding earlier this year. This time, I don't think the flooding is going to be just confined to the river valley... I believe the flooding will be more widespread as nearly 2 feet of rain could fall in isolated spots. The image below shows the 5 day rainfall forecast, which will take us through the middle of next week.
Flooding Concerns Posted For New Orleans
Nearly 6 years after Hurricane Katrina, a much less developed tropical wave is plowing into Louisiana. Storm surge and strong winds definitely don't look like the threats here. Tropical Storms are notorious for their heavy rainfall potential and I don't think Lee will disappoint in that category. In fact, I think Tropical Storm Lee is going to be more than just a minor inconvenience. Flooding concerns have already been posted for counties and perishes along the Gulf Coast where rainfall amount could be quite astounding.

Hurricane Katia Continues Westward
I don't want to spend much time on Katia, but it's worth mentioning since some of the latest forecasts have Katia nearing the New England states by next weekend. Here's the latest on KATIA from the National Hurricane Center
