Unnamed Tropical Storm

June 11-16, 1956

A tropical depression formed in the Bay of Campeche late on June 11^th and strengthened into a tropical storm during the afternoon on June 12^th as it continued to move due northward. The tropical storm continued to slowly strengthen as it moved northward, being steered by a mid to upper level ridge of high pressure across the Caribbean and a mid to upper level low over Texas and Louisiana. The tropical storm made landfall near Cocodrie, Louisiana at 11 AM CST June 13^th with maximum sustained winds of 60 mph (50 knots).

The weakening tropical storm continued northward across Southeast Louisiana and Southwest Mississippi that afternoon and evening, weakening to a tropical depression near Vicksburg, Mississippi. The upper level low over Louisiana began to turn the weakening depression northwest across Arkansas, where it dissipated early on the 16^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.
