A tropical depression formed across the eastern Gulf during the afternoon August 25^th and strengthened to a tropical storm later that evening. The tropical storm slowly strengthened on August 26th as it moved northward. A building mid to upper level ridge of high pressure over the Central U.S. began to turn the tropical storm westward by the afternoon of August 26^th. The tropical storm made landfall just east of New Orleans, Louisiana at 10 PM CST August 26th with maximum sustained winds of 50 mph (45 knots).

The weak tropical storm continued westward across Southern Louisiana on August 27th. The storm weakened into a depression later that evening as it crossed the Sabine River into Southeast Texas, and dissipated over East Texas the afternoon of August 28^th. This storm did not receive a name, as it was found to be of tropical storm strength during the post season analysis. Click here for an interactive map of the tropical storm.
