...Todays Topic for Severe Weather Awareness Week is Watches
and Warnings...

The National Weather Service, in cooperation with the Arkansas
Department of Emergency Management, has proclaimed the week of
February 28th through March 6th as Severe Weather Awareness Week
in Arkansas.

A different topic will be discussed each day, and todays topic
is watches and warnings.

Surrounding an event featuring severe thunderstorms, watches
and warnings are issued to help you prepare for the elements.

Severe thunderstorms produce damaging straight-line wind gusts
of 58 mph or greater, quarter size hail or larger, and/or
tornadoes.

When conditions are favorable for severe storms, a watch is
issued by the Storm Prediction Center /SPC/ in Norman, Oklahoma.
SPC is a part of the National Weather Service.

Watches often encompass a large area, sometimes several states,
and are valid for roughly six hours.

When storms develop and are classified as severe, warnings are
issued by your local National Weather Service office.

Warnings are posted for one or more counties and are valid for
an hour or less.

When severe weather warnings are issued in the future /starting
April 28th/, there is something to mention. For a standard
Severe Thunderstorm Warning /60 mph winds and one inch hail/,
nothing will change. However, if 70 to 80 mph gusts or golf
ball to tennis ball size hail are in the warning, it will
result in a thunderstorm damage severity of "considerable".
For 80+ mph gusts or 2.75+ inch /baseball or larger/ size hail,
the damage tag will be labeled as "destructive". This tag will
result in the activation of a Wireless Emergency Alert /WEA/
through the Integrated Public Alert and Warning System /IPAWS/,
and this will go to cell phones within the warning polygon.

With a watch in place, severe storms might happen. When
warnings are in place, severe storms are happening.

...Watch and Warning Rules to Follow...

You should be ready to go to a safe place when a watch is in
effect. Monitor conditions for several hours or until the
watch expires or is cancelled.

You should go to your safe place when a warning is in effect.
Stay put until storms pass and/or the warning expires or is
cancelled.

The safest place to be is a safe room or a basement. If these
are not available, go to an interior room on the lowest floor
of a house or building. Put as many walls between you and the
outdoors as possible.
