Tropical Storm Debra was the second of two tropical storms to hit the United States in the 1978 Atlantic hurricane season. The fourth named storm of the season, Debra developed from the interaction between a high-altitude cold low and a lower tropical wave in the Gulf of Mexico. Forming on August 25, it was upgraded to Tropical Storm Debra based on data from a Hurricane Hunter aircraft. As Debra approached the coast, it attained peak winds of 60 mph (95 km/h). The storm made landfall on the coast of Louisiana, east of the Texas border. Two deaths were caused by the storm. Debra weakened as it moved inland and ultimately dissipated on August 29 over Arkansas.
