Public Information Statement
Issued: 3:46 PM EST Feb. 24, 2017 – National Weather Service

A Severe Thunderstorm Watch has been issued by the National Weather
Service in Michigan. In the interest of public safety, the following
safety rules are provided. Public and commercial broadcast stations
serving the affected area are asked to frequently broadcast these
messages while the watch is in effect.

As a quick reminder, the term watch means conditions are favorable
for the development of severe weather in the designated area. During
a watch, there is no cause for immediate concern. You should go
about your normal business, but keep abreast of weather developments.
Public safety officials should, however, activate prearranged plans.

A warning, on the other hand, means a severe thunderstorm or tornado
has been observed or indicated by radar. People in the path of the
storm should take immediate precautions as outlined here.

Severe thunderstorms produce strong damaging winds of 58 mph or
greater, large hail of one inch in diameter or greater, heavy
rain and deadly lightning. Winds in excess of 58 mph can push over
shallow rooted trees, break off tree limbs about the size of your
wrist and damage chimneys and TV antennas. In rare occasions,
severe thunderstorms can produce winds in excess of 80 mph which
could break windows, Peel surfaces off of roofs, snap large trees
and move trailer homes and automobiles. Hail one inch in diameter
or larger can damage windows, vehicles and exterior finishes of
buildings, especially if accompanied by severe winds.

Persons should stay indoors and away from areas with loose items
that could become flying debris. Severe thunderstorms can and
occasionally do produce tornadoes so be prepared to move to an
appropriate shelter should it become necessary. Lightning is one
of the worst killers, so stay indoors and avoid using electrical
appliances. You should get out of open fields and off of farm or
other types of heavy equipment. Avoid towers or tall trees. If
on a boat or swimming, get out of the water and to shore as
quickly as possible. Also avoid areas subject to flash flooding.

If you lose power, and plan to use a portable power generator in
your home be careful. Observe all safety precautions to avoid
Carbon monoxide poisoning, electrocution or a fire. Portable
generators should only be operated outdoors in a dry and well
ventilated area.
