Public Information Statement

Statement as of 7:00 AM EDT on April 27, 2015

The National Weather Service has declared the week of April 27th
through may 1st, severe weather awareness week in New England. This is
the first in a series of five public information statements on various
topics related to severe weather awareness.

During severe weather awareness week, the National Weather Service
encourages the public to become more aware of the threats associated
with thunderstorms, so they can act appropriately when severe storms

... Severe weather awareness - some basic definitions...

New England will soon be transitioning from early Spring-like weather to
a more Summer-like weather pattern. With the warmer weather comes an
increasing threat of thunderstorms. By definition, every thunderstorm
contains lightning and is, therefore, a potentially deadly storm. In
addition, certain thunderstorms present other threats, as well. These
threats include high winds, hail, tornadoes, and flash flooding.

The National Weather Service uses a watch and warning program to alert
the public to potentially threatening weather. In the summertime,
watches and warnings are issued for severe thunderstorms, tornadoes, and
flash flooding, and special marine warnings are issued for gusty winds
in marine areas. Here are some basic definitions.

A watch indicates that the atmospheric conditions are favorable for
severe weather to develop.

     If a watch has been issued for your area, keep an eye on the
     sky, and monitor NOAA Weather Radio or your local broadcast
     media for any possible warnings.

A warning indicates that severe weather is imminent or is already

     If a warning has been issued for your area, be prepared to seek
     a safe shelter if you are in the path of the storm.

Here are some basic definitions of the events for which watches and
warnings are issued.

Severe thunderstorm - a thunderstorm that produces damaging wind
                      gusts of 58 mph or more, and/or hail 1 inch or
                      greater in diameter.

Tornado - a violently rotating column of air that extends from the
          cloud to the ground.

Flash flood - flooding that occurs very rapidly, usually due to
              very heavy rain from a slow moving thunderstorm.

In addition to these warnings which are issued for land areas, the
National Weather Service issues special marine warnings for marine

Special marine warning - issued for marine areas for storms with
                         frequent wind gusts of 34 kts (about 39
                         mph) or greater.

One of the best ways to monitor these conditions is by purchasing an
alert-activated NOAA Weather Radio for your home or business. If you
are within the broadcast range of a NOAA Weather Radio transmitter, tone
activated NOAA weather radios can be set to automatically turn on when a
severe thunderstorm, tornado, or Flash Flood Warning has been issued by
the National Weather Service. In addition, alert-activated weather
radios can be programmed to activate only if the warning has been issued
for the county(ies) that you are interested in. For more information on
purchasing a NOAA Weather Radio, contact the National Weather Service.
NOAA weather radios can often be purchased at stores that sell small
electronic equipment.

Finally, if you are caught in a severe thunderstorm or tornado, know
what to do to minimize the risk that you or someone with you could be
killed or seriously injured from the storm. And, after the storm, be
sure to report storm damage to local law enforcement agencies and ask
them to relay the information to the National Weather Service.
