Wider weather episode

Tropical Storm Helene formed in the NW Caribbean Sea on September 24. Helene moved northward into the Gulf of Mexico where it strengthened into a hurricane on September 25. During the day on September 26, Helene remained off the coast of Florida and an upper low over the southeast US led to strong moisture transport and strong forcing over the area. Heavy rain rates and training bands led to flash flooding developing. Increasing shear associated with the hurricane also led to the development of several tornadoes in heavy rain bands.
