Keeping yourself up to date

No power, no Internet? A batterypowered radio may be your best way to get information on what’s going on.

Tune in to AM radio. In the Bay Area, KGO 810 and KCBS 740 carry regular news updates, and each is set up to run emergency information broadcasts from local authorities.

Listen for a warning siren. The city of San Francisco, for example, will blast its sirens during a major disaster, which is a cue to listen to an emergency radio broadcast. ( The sirens are tested at noon every Tuesday.)

Consider buying an emergency radio. The radio includes channels that regular AMFM radios don’t get, including essential weather and disaster broadcasts from the National Oceanic and Atmospheric Administration. To find your local NOAA station, go to https:// www. weather. gov/ nwr/ station_ listing.
