30 kn in a 24-h period. Relocated A term used in an advisory to indicate that a vector drawn from the preceding advisory position to the latest known position is not necessarily a reasonable representation of the cyclone's movement. Reformed A term used in an advisory to indicate that the center of a tropical cyclone, usually weak, has dissipated and a new center has formed at a different location. This will sometimes lead to an incorrect representation of movement. The center of a cyclone can reform multiple times in its life. The new center is not given a new name from the rotating name lists, unless there is a period of time between old center dissipation and new center reformation. Remnant Low A post-tropical cyclone that no longer possesses the convective organization required of a tropical cyclone...and has maximum sustained winds of less than 34 knots. The term is most commonly applied to the nearly deep-convection-free swirls of stratocumulus in the eastern North Pacific. S Saffir-Simpson Hurricane Scale/Saffir-Simpson Hurricane Wind Scale (SSHWS) The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 categorization based on the hurricane's intensity at the indicated time. The scale provides examples of the type of damage and impacts in the United States associated with winds of the indicated intensity. Sea surface temperature Water temperature close to the surface of a large body of water, such as an ocean or sea. Normally, an ocean temperature of spanning through at least a 50-metre depth is one of the six requirements needed to maintain the special mesocyclone that is the tropical cyclone. These warm waters are needed to maintain the warm core that fuels tropical systems. Severe Tropical Cyclone A term used by RSMC Nadi and the Tropical Cyclone Warning Centers in Perth, Darwin, Jakarta, Port Moresby and Wellington to describe an Australian category 3, 4 or 5 tropical cyclone that has wind speeds greater than . Severe Tropical Storm A term used by the Japan Meteorological Agency to describe a typhoon with 10-minute windspeeds between . Storm surge An abnormal rise in sea level accompanying a hurricane or other intense storm, and whose height is the difference between the observed level of the sea surface and the level that would have occurred in the absence of the cyclone. Storm surge is usually estimated by subtracting the normal or astronomic high tide from the observed storm tide. Storm
