Tropical Storm Debby (2006)
Early in its life, Debby was forecasted to pass through the southern Cape Verde islands as a tropical storm, possibly causing life-threatening flooding. Most computer models consistently predicted Debby to move to the northwest throughout its lifetime, though intensity was more of a problem for forecasters. The National Hurricane Center continually predicted Debby to strengthen into hurricane status, though strong vertical shear eventually prevented the storm from becoming a hurricane.
