Dvorak technique
The origins of Hurricane Fausto were from a tropical wave that emerged into the eastern Atlantic Ocean from the west coast of Africa on August 11. It crossed the Atlantic and Caribbean uneventfully. The tropical wave ultimately entered the Eastern Pacific Basin on August 17. Rapidly organizing, the system was classified using the Dvorak technique at 1800 UTC on August 18. Although a broad closed circulation was present on August 19, the system became less organized and thus was not immediately classified as a tropical depression.
