If you stay informed, you'll know when disasters are going to strike.
Be sure to keep up with information from your local government leaders and media. If the Emergency Alert System is activated, tune to 740 AM or 88.7 FM to receive emergency messages. And many jurisdictions offer text message or email notifications. But don't just rely on one source--stay informed by using multiple sources of information.
Another way to stay informed is to have a NOAA Tone-Alert Radio (with a battery backup). The NOAA radio, also called a weather radio, is programmed to listen to National Weather Service forecast broadcasts and sound an alarm is severe weather is predicted for your area. NOAA Weather Radios are also available with strobe lights and other non-audible alert methods for people who are deaf or hard-of-hearing.
