The SAME message the NWR sends contains information, which
tells the radio the time period for which the alert is valid. The
time can be set from 15 minutes up to 6 hours. When the
designated time has passed the display message and light will be
reset to their normal state.
Environment Canada is developing a warning system using
SAME technology. Some added events not currently used by
NWS are used in the Canadian system. These are also decoded
according to this table.
