High Quality Content by WIKIPEDIA articles! Hurricane Otis was a moderate hurricane that threatened the Baja California Peninsula but dissipated before landfall. Otis developed on September 28, 2005, off the western coast of Mexico, from a tropical wave that emerged from the western coast of Africa and traversed the Atlantic Ocean during the preceding several weeks. After attaining tropical storm status on September 29, the storm moved in a generally northwestward direction for most of its duration. It ultimately peaked at Category 2 intensity on the Saffir–Simpson Hurricane Scale before beginning to weaken. The storm degenerated into a tropical depression on October 3 and dissipated fully on October 5, near the coast of Baja California Sur. Preparations for the storm were completed on the Peninsula; tropical cyclone watches and warnings were declared and numerous shelters opened. However, the storm`s effects were minimal, and limited to gusty winds with heavy rainfall. No major damage was reported.
