Subject: Changes to the Tsunami Threat Message effective
         Wednesday, October 1, 2014

Effective Wednesday, October 1, 2014, at 0000 Coordinated
Universal Time (UTC), the NWS Pacific Tsunami Warning Center
(PTWC) in Honolulu, HI, will eliminate the use of alerting terms
"watch" and "warning" in its WEPA40 PHEB Tsunami product for the
Pacific and instead provide rapid notification of potential
tsunami threats. This change is being made at the request of
member states of the Pacific Tsunami Warning and Mitigation
System to improve the service.

PTWC will issue Watch/Warning/Advisory products under different
headers for U.S. domestic locations which were formerly provided
tsunami alerts exclusively through the WEPA40 PHEB product. For
further information on these Watch/Warning/Advisory US domestic
locations please see:
