High Quality Content by WIKIPEDIA articles! Tropical Storm Isidore was the 15th tropical cyclone and 9th named storm of the 1984 Atlantic hurricane season. Isidore formed as a tropical depression on September 25, while situated off the southeastern Bahamas. The depression headed west, and was upgraded to a tropical storm in the central Bahamas the next day. It made landfall near Jupiter, Florida, and retaining tropical storm strength, Isidore curved to the northeast, emerging over water near Jacksonville, Florida. Isidore continued northeast until it was absorbed by a frontal system on October 1. Though damage was generally light, the storm affected several regions from the Bahamas to the U.S. East Coast. One death was reported in Florida, and total damage is estimated at $1 million (1984 USD).
