What to do when you receive an emergency alert

In an emergency situation, an alert will be sent by Redwood City authorized personnel and you will receive alerts based on your profile preferences either to email, cell phone, text message or home phone. Read these messages promptly and follow the instructions. Additional instructions may follow throughout the emergency situation so keep your phone near you. Even if the cell phones are busy, text messages should still come through to your phone.

When you do receive an alert message, please follow the instructions on that message. Please do NOT call 911 or an Emergency Communications Center as they are already aware of the emergency -- and your call will tie-up precious resources, further endangering the emergency situation. We will make every effort to update websites in real time with more information about the emergency. In addition, you should tune to local TV and radio.
