A Synoptic Review of Tropical Storm Cindy and the Impacts to the North Central Gulf Coast (305)

This study discusses the evolution and impacts of Tropical Storm Cindy. Tropical Storm Cindy made landfall near the Texas-Louisiana border in the early morning hours of 22 June 2017. Vertical wind shear in the background environment and dry air entrainment into the storm caused far-reaching effects well removed from the center of circulation. Upper air, satellite, and radar data were analyzed to determine evolutionary trends with regard to the latter characteristics. Although very heavy rain fell, it was forecast to be greater in extent and intensity versus what actually verified. Widespread rainfall totals in the North Central Gulf Coast of generally less than 10 inches fell over the duration of the event. This did cause localized flash and river flooding, but not to the extent initially anticipated. The storm also spawned ten tornadoes with two being EF-1s, and eight, EF-0s. By examining the synoptic scale evolution and corresponding patterns of associated thermodynamic and kinematic ingredients, it is possible to gain a greater understanding of both how the event evolved and possibly why the rainfall pattern did not materialize to its fullest potential.
