In addition, a special advisory package may be issued at any time to advise of significant unexpected changes or to modify watches or warnings.

For these land-threatening "potential tropical cyclones", NHC will issue the full suite of advisory and watch/warning products that previously had been issued only for tropical cyclones. Potential tropical cyclones will share the naming conventions currently in place for tropical depressions, being numbered from a single list (e.g., "One-E", "Two-E", "Three-E", 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 is also 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 WTPZ61-65 KNHC, and under AWIPS header MIATCUEP1-5.
