Fefa passed directly over Hawaii as a tropical depression on 7 August 1991. It had peaked far out at sea at 105 kt and was weakening as it neared the islands. Only 27 official forecasts survive in the archive, all issued more than a day before the closest pass, so the replay stops early. Forecasts issued from Honolulu in this era were never written into the digital record.
