New Siren Activation Policy to Include
Severe Thunderstorms (September 2008)
 As
we all know, a severe thunderstorm with straight line winds of 70
mph or greater can do as much damage as a weak (EF0) tornado.
Effective immediately, Oakland County Emergency Response and
Preparedness will activate the County's Outdoor Warning sirens for
tornados and severe thunderstorms with damaging winds at/near 70 mph
or greater in Oakland County and within a ten mile buffer around the
County (this will give citizens living close to the border more time
to take cover).
In the past, the outdoor warning sirens were only activated when
a tornado was sighted or strongly indicated on radar. This
change in policy is a result of the tornado touchdown in Holly last
year and the severe thunderstorm with damaging 80mph winds in early
June.
This doesn't mean that the sirens will go off every time severe
weather is in the area. Had the 70 mph policy been in place,
Oakland County would have activated the outdoor warning sirens an
additional 6 times since January 2006.
