Track of TS 13L

In late August, a tropical wave producing scattered showers and thunderstorms entered the Western Caribbean. Moving generally west-northwestward, the wave began to organize in the southeastern portion of the Gulf of Mexico.

During the afternoon hours of September 1, the hurricane hunters went out to investigate the well-defined wave, and found a closed low-level circulation. Thus, advisories were initiated on Tropical Depression Thirteen.

Moving northwest, the tropical depression was upgraded to a tropical storm, given the name “Lee” on September 2. Continuing to organize, Lee reached a peak intensity of 60 mph early on September 3, while located just south of Louisiana.

At 4AM CDT September 4, Lee made landfall roughly 50 miles to the southwest of Lafayette, Louisiana with maximum sustained winds of 45 mph. Further weakening occurred as Lee moved across Louisiana, and the last NHC advisory on Lee was issued early on September 5. Here, the storm can be seen on the right side of the main image, moving over Louisiana.
