Tropical Depression Eight formed from a tropical wave 1130 mi (1815 km) east of the Lesser Antilles on September 12, just before the system that eventually became Humberto formed. It was slow to develop and became Tropical Storm Ingrid early on September 14. Shearing winds from a tropical upper tropospheric trough soon weakened the cyclone, it returned to depression strength on September 15, and the final advisory was issued on September 17 as the system degenerated into an open wave north of the Leeward Islands. Ingrid was the first storm of the 2007 season not to threaten land, and there were no reports of damage or casualties.
