Tropical Storm Barbara

July 27-31, 1954

Early on July 27^th, an area of low pressure along a decaying frontal zone developed offshore Southeast Louisiana. By daybreak, it is estimated that a tropical depression developed south of Grand Isle, Louisiana. The depression tracked northwestward, intensifying into Tropical Storm Barbara early on July 28^th.

Tropical Storm Barbara continued to slowly move northwest and slowly intensified. Barbara made landfall between Cameron and Grand Chenier, Louisiana at 4 AM CST July 29^th with maximum sustained winds of 60 mph (50 knots) and a minimum central pressure of 999 millibars (29.50 inches). Barbara slowly weakened after landfall, tracking northwest across Southwest Louisiana for the remainder of the morning and moved across Southeast Texas by the afternoon. Barbara weakened to a depression by the evening hours and dissipated by daybreak on July 30^th across Central Texas. Click here for an interactive map of Tropical Storm Barbara.
