 A tropical wave passed through the islands of Cape Verde on September 6 and tracked westward at about 19 mph (31 km / h). Early on September 9, a tropical depression developed while located about midway between Cape Verde and the Lesser Antilles. The depression moved northeastward and by September 10 it strengthened into Tropical Storm Flora. A reconnaissance aircraft flight into the storm on September 11 recorded winds of 75 mph (120 km / h); thus, Flora became a hurricane. Around the time, the storm attained its peak intensity with maximum sustained winds of the same velocity and a minimum barometric pressure of 994 mbar (29.4 inHg). Flora then accelerated northeastward toward the Azores. During another reconnaissance flight on September 12, no evidence of a tropical cyclone was reported. Thus, Flora became extratropical at 1200 UTC that day.
