Tropical Storm Heidi was the last of the 4 tropical systems to develop from the extended surface trough of low pressure. A tropical depression developed out of this on September 11 northeast of the Bahamas, and became Tropical Storm Heidi on the 12th 400 miles east of Jacksonville. The storm never got well organized, partly due to the outflow from Ginger. As it looked like it would go out to sea, a large low-pressure system over the Appalachian Mountains forced the system westward into Maine, where it dissipated on the 15th.
