Tropical Storm Helene was a long-lived tropical cyclone that oscillated for ten days between a tropical wave and a 70 mph (110 km/h) tropical storm. It was the twelfth tropical cyclone and eighth tropical storm of the 2000 Atlantic hurricane season, forming on September 15 east of the Windward Islands. After degenerating into a tropical wave, the system produced flooding and mudslides in Puerto Rico. It reformed into a tropical depression on September 19 south of Cuba, and crossed the western portion of the island the next day while on the verge of dissipation. However, it intensified into a tropical storm in the Gulf of Mexico, reaching its peak intensity while approaching the northern Gulf Coast. Tropical Storm: peak winds of 70 mph (60 knots), lowest pressure 986 mb. September 15 – September 25, 2000. Landfall: September 22 at 40 mph, 30.5°N 86.6°W. Accumulated cyclone energy: 3.5.
