# List of named storms (O)

Storms are named for historical reasons to avoid confusion when communicating with the public, as more than one storm can exist at a time. Names are drawn in order from predetermined lists. For tropical cyclones, names are assigned when a system has one-, three-, or ten-minute winds of more than 65 km/h (40 mph). Standards, however, vary from basin to basin. For example, some tropical depressions are named in the Western Pacific, while within the Australian and Southern Pacific regions, the naming of tropical cyclones are delayed until they have gale-force winds occurring more than halfway around the storm center.
    This list covers the letter O.
