Tornado Warning Sirens
The City of Lockport warning sirens are tested on the first Tuesday of each month at 10:00 a.m. If the
sirens are activated at any other time, this means a severe weather emergency, (such as a confirmed tornado or
funnel cloud) has been detected in close proximity to the City and residents should seek cover immediately.
The sirens will make a high-pitched tone for a period of three minutes and the warning shall be in effect for a
period of one hour. (The City does not sound an "all clear" siren.) Warning sirens are located at various
locations throughout the city. When the weather appears threatening, don't rely solely on sirens to protect you and
your family. Stay indoors and monitor local television and radio stations for watches and warnings! Remember, you
are the person most responsible for your safety!
