The sun sets behind power lines in Long Beach.

A Southern California week that began with record-breaking heat and could end with the remnants of a hurricane is a good reminder to sign up for services that notify you when trouble’s heading your way.

A host of agencies and companies offer text, email and other alerts that can help you prepare for looming disasters. Here’s how to get in on the automated flow of information.

Flex Alerts and other power issues

If you’re a customer of Southern California Edison, visit the company’s Preference Center to sign up for alerts by email, text or phone call. In addition to notifications about Flex Alerts and scheduled blackouts, you can be alerted about repairs and peak rate periods.

In the city of Los Angeles, you can sign up for text or email alerts about power issues on the L.A. Department of Water and Power website.

Customers with San Diego Gas & Electric will need to download an app to get their alerts. And if you’re in Pacific Gas & Electric’s turf, go to the alerts page on its website to sign up for notifications about outages, rates, scheduled repairs and other issues.

Wildfires

Cal Fire offers to send you text messages to keep you updated about fires in your area. You can sign up on the Ready for Wildfire site.

While you’re there, you can also create a wildfire readiness plan, including steps you can take to make your property less vulnerable to fire and to be ready for an evacuation order. The plans are customized to your location and living situation.

Earthquakes

ShakeAlert is an earthquake detection and warning system developed by the U.S. Geological Survey with the help of multiple partners in government and academia. It is designed to send alerts when the first signs of a major earthquake are detected, giving people a few precious seconds or even tens of seconds to prepare for larger shockwaves.

Earthquake warnings may be sent over the Wireless Emergency Alert system, which reaches most cellphones in use today (see below). And smartphones in California running Google’s Android operating system have the built-in ability to receive ShakeAlert messages.

Beyond that, there are at least three free apps available for Apple and Android smartphones that will receive and display ShakeAlert messages in this state: MyShake from UC Berkeley, QuakeAlert USA from Early Warning Labs, and SD Emergency, a general-purpose disaster-preparedness app by San Diego County.

Severe weather and other regional emergencies

If you’ve got a cellphone, chances are good that you’ll automatically receive the Wireless Emergency Alerts broadcast by federal, state, tribal and local authorities. These include Amber Alerts about possibly abducted children; “imminent threat alerts” about extreme weather, disasters, active shooters and other emergencies in your area; and more routine public safety alerts.

For example, the California Office of Emergency Services used the system Wednesday to send out a “severe alert” about the need to conserve energy. “Power interruptions may occur unless you take action,” it warned, urging recipients to “turn off or reduce nonessential power” until 9 p.m. (It worked; blackouts were avoided.)

This system can also deliver text messages from the president in the event of a national emergency. So far, that particular capability has been used only once, in a test three years ago.

Verizon, AT&T and T-Mobile all deliver Wireless Emergency Alerts at no charge to customers, as do some prepaid phone services, but older mobile phones may not be able to receive the messages or take advantage of the system’s more advanced features. More compatibility information is available from Verizon, AT&T, T-Mobile and other service providers’ websites.

Local notifications

The state’s counties have their own alert systems to notify participants about local public safety emergencies. In Los Angeles County, the system — Alert LA County — sends out messages via text, phone call or email when residents need to evacuate immediately, to prepare to evacuate, or to shelter in place. In other words, it’s for really serious stuff.

The notifications are free, but you have to sign up for them. To do so, visit the “Stay Informed” page on the Ready LA County site.

The city of Los Angeles, meanwhile, offers an alert system called NotifyLA that can send notifications via text, email or phone call. You can sign up through Everbridge, which operates the system. For other cities’ alert systems, check out this list of links provided by L.A. County.

Finally, Everbridge’s Nixle platform carries local public safety information from numerous agencies, including the Los Angeles Police Department, the L.A. County Sheriff’s Department and the California Highway Patrol. Topics covered include traffic tie-ups, criminal activity, missing persons and severe weather.

You can sign up for text alerts by texting your ZIP Code to 888777. Those messages will count against your monthly allotment, if your mobile carrier charges you for text messaging. As an alternative, you can download the Nixle app and receive the alerts through the internet instead of texts.

NOAA Weather Radio

If you don’t have a smartphone or just want a backup system for emergency alerts, you can tune in to the National Oceanic and Atmospheric Administration’s broadcast network.

NOAA Weather Radio stations pump out an around-the-clock stream of official National Weather Service warnings, watches and forecasts. But they also serve as “all hazards” alert systems, transmitting warnings and “post-event information” about natural disasters, environmental hazards and public safety incidents.

There’s just one catch: NOAA Weather Radio operates on frequencies that your typical car radio can’t receive. You’ll need a specialized device — NOAA’s website offers a list of radios and retailers that sell them.

Tsunamis

If the earth is shaking under the ocean instead of under your feet, that raises the possibility of a different threat: a tsunami. It’s not as unusual an event as you might think; since 1880, a tsunami has hit Los Angeles County every three to four years on average.

Granted, most have been pretty meek by the time they reached Venice Beach. But still, the potential is there, as we saw in 2011, when a tsunami triggered by an earthquake off the coast of Japan caused $100 million in damage to California harbors and ports.

The feds will transmit tsunami warnings over the Wireless Emergency Alert system and NOAA Weather Radio. But if you’d like to hear more directly from the government’s Pacific Tsunami Warning System, you can check its live online feed or follow its Twitter posts.

COVID-19

If you’re still concerned about catching the highly infectious coronavirus, you can install the CA Notify app on your smartphone. The app will alert you when you come into close contact with another CA Notify app user who has recently tested positive.

Designed to preserve the confidentiality of users, the app won’t tell you who the infected person was — just that you were in close contact with someone who has the virus. The system works, however, only if it’s widely used, if users get tested regularly, and if users share their positive test results with the app.
