Public Information Statement
National Weather Service Honolulu HI
154 PM HST Tue Jan 23 2018


The National Weather Service in Honolulu has received questions
from people today wondering why their cell phones did not alert
them for the Tsunami Watch which was issued last night.

Wireless Emergency Alerts (WEA) are emergency messages sent by
authorized government alerting authorities through your mobile
carrier. Government partners include local and state public safety
agencies, FEMA, the FCC, the Department of Homeland Security, and
the National Weather Service. Alerts are sent automatically to
WEA-capable phones during an emergency.

As of January 2018, only the following most urgent National
Weather Service warnings are sent nationwide as WEA messages:

Tsunami Warnings
Tornado Warnings
Flash Flood Warnings
Hurricane Warnings
Typhoon Warnings
Dust Storm Warnings
Extreme Wind Warnings

In order to minimize disruption to wireless device users,
watches, advisories and other types of warnings are not
disseminated via WEA and will not alert your phone. However, many
of these warnings and watches are tone-alerted via NOAA Weather
Radio. This is another option for users who wish to be immediately
notified of hazards such as a Tsunami Watch.
