Hurricane Flossy

September 20-25, 1956

A tropical depression formed just east of the Yucatán Peninsula across the Northwest Caribbean Sea the afternoon of September 20^th. The depression moved west northwest, moving inland early on September 21st and began to move northwestward across the Yucatán Peninsula through early on September 22^nd.

Upon entering the southern Gulf, the depression strengthened into Tropical Storm Flossy by daybreak on September 22^nd. Flossy turned more north northwest and eventually northward, gradually intensifying as it headed towards the Louisiana coast. By the afternoon of September 23^rd, Flossy intensified into a minimum hurricane as it began to turn northeast with an approaching upper level trough and cold front.

Hurricane Flossy made landfall across lower Plaquemines around 4 AM CST September 24^th with maximum sustained winds of 85 mph (75 knots) and a minimum central pressure of 980 millibars (28.94 inches). Flossy made a secondary and final landfall near Destin, Florida around 6 PM CST as it accelerated east northeastward. Flossy quickly weakened overnight and became an extratropical storm on September 25^th as it merged with the approaching cold front. Click here for an interactive map of Hurricane Flossy.
