New Siren Activation Policy to Include Severe Thunderstorms (September 2008)

Severe Storms headline on newspaperAs 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.
