This product is issued four times per day from June 1 through November 30 at 2 AM, 8 AM, 2 PM, and 8 PM Hawaii Standard Time. A Special Tropical Weather Outlook will be issued to provide updates, as necessary, in between the regularly scheduled issuances of the Tropical Weather Outlook. Special Tropical Weather Outlooks will be issued under the same WMO and AWIPS headers as the regular Tropical Weather Outlooks. A standard package of products, consisting of the tropical cyclone public advisory, the forecast/advisory, the cyclone discussion, and a wind speed probability product, is issued every six hours for all ongoing tropical cyclones. In addition, a special advisory package may be issued at any time to advise of significant unexpected changes or to modify watches or warnings. There is an option to issue advisories, watches, and warnings for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 72 hours. For these land-threatening "potential tropical cyclones", the full suite of advisory and watch/warning products will be issued. Potential tropical cyclones share the naming conventions currently in place for tropical depressions, being numbered from a single list (e.g., "One-C", "Two-C", "Three-C", etc.). The Tropical Cyclone Update is a brief statement to inform of significant changes in a tropical cyclone, to post or cancel watches or warnings, or to provide hourly position updates between intermediate advisories when the storm center is easily followed by radar. The Tropical Cyclone Update can also be used in lieu of or to precede the issuance of a special advisory package. Tropical Cyclone Updates, which can be issued at any time, can be found under WMO header WTPA61-65 PHFO, and under AWIPS header HFOTCUCP1-5.
