TWS Tsunami Products
(Effective April 3, 2017)
Tsunami messages are National Weather Service (NWS) products. NWS products are described by both a World Meteorological Organization (WMO) Header and an Advanced Weather Interactive Processing System (AWIPS) ID. The following table describes the products issued by the two NWS Tsunami Warning Centers (click on the product for an example).
WEPA41 and WEXX20 are segmented Warning, Watch, and Advisory products which contain Universal Geographic Code and NWS Valid Time Event Codes.
WEHW40, WEZS40, WEGM40, WEAK51, WECA40 and WEXX30 are Warning, Watch, and Advisory products which are provided in a bulleted format intended for easy reading.
WEAK61, WEAK63, WECA50, WECA32, WEXX40 and WEXX42 have the same content as WEAK51, WEAK53, WECA40, WECA42, WEXX30 and WEXX32, but in Spanish.
WEPA40 and WECA41 are intended for international authorities and users. While these products do mention U.S. states and territories, they do not reflect additional modeling and analysis conducted by the Pacific Tsunami Warning Center to fine tune the forecasts and alert levels for these coasts. U.S. audiences should refer to the products specific to their region as noted in the table below.
