Olaf was a weak but persistent tropical storm that made two landfalls and took an erratic path. A tropical depression formed September 26, was upgraded a tropical storm at the next advisory, and immediately moved north. On September 29, Olaf made landfall near Salina Cruz. Olaf dissipated, and the remnants moved far out to sea. During later reanalysis, Olaf was found to be a tropical depression during most of this time, but at the time was considered dissipated.
