Does Madison, Wisconsin, do a siren test every Wednesday of the week, or a Wednesday every month? The sirens went off around noon today and last for maybe 2 minutes. Why would a siren test last so long? Lancaster never did an actual siren test (unless you count the 10 second noon whistle), so I am curious as to what they check while the sirens go off during those 2 minutes?
Thanks,
