Due to overcast skies and rain in the forecast, today’s outdoor warning siren test has been cancelled.

Even though the sirens won’t sound today, this is still a great opportunity to review your emergency plans and check your preparedness kit. Make sure supplies are stocked, batteries are fresh, and everyone in your household knows what to do in case of severe weather.

Stay weather aware and stay prepared.
