STATE
OF WASHINGTON
EMERGENCY ALERT SYSTEM

NOAA/NWS
Information and Maps
[February
10, 2007]
National
Weather Service (NWS) offices in
Seattle, Spokane,
Portland, and Pendleton are authorized
to activate the Emergency Alert System
(EAS) in Washington state. These four NWS offices have
short-fuse county warning
responsibility for their respective
parts of Washington (see attached
map). EAS event codes that NWS uses
are listed in Tab 17 (EAS Master
List). EAS activation is recommended
for short-fuse events (less than six
hours to the event). NWS EAS message authentication
is conducted through the EAS
origination code.
NWS
EAS messages are transmitted in
Washington through
NOAA Weather Radio (NWR) (see attached
map and list of stations).
If
a NWS office is unable to activate EAS
for a weather event because office
communications are down or one or more
NWR transmitters are off the air,
Washington State Emergency Management
serves as the backup and can transmit
the EAS message for the NWS.
To
report any kind of NOAA Weather Radio
transmitter outage trouble, use this
web site link to report the problem www.nws.noaa.gov/nwr/outages.html
Watch/Warning
Definitions
Outlook - The
initial notice of potential
hazardous flooding or weather. Issued up to 5 days in
advance of a potential event, it is
the initial message to help raise
the first level of community
awareness and preparedness.
Watch - Conditions
are favorable for hazardous weather
to occur in a designated geographic
area, but not yet certain. For short-fuse severe weather
events (e.g. - severe thunderstorm,
tornado), a watch can be issued up
to 12 hours in advance. For long fuse events (e.g. -
flood, high wind), a watch is issued
from 12 to 48 hours in advance.
A
watch is a planning tool, a second
higher level of awareness and
preparedness, permitting those who
need to take preliminary actions to
do so in a timely manner. Be alert,
monitor NOAA Weather Radio or other
weather information sources, and be
PREPARED to take immediate action if
the watch is changed to a warning.
Warning - Hazardous
flood or significant weather is
occurring or imminent within the
next 12 hours in the designated
geographic area(s). TAKE ACTION NOW to protect
life and property!
