American emergency alert systems continue to face challenges in reaching everyone in harm's way

Despite significant improvements in American emergency alert technology, the country often fails to broadcast warnings that reach people in time. "Federal, state and local authorities share responsibility for alerting citizens that they are in danger," report Drew FitzGerald, Josie Reich and Caitlin Ostroff of The Wall Street Journal. "But the country’s patchwork of digital and physical emergency-alert tools is often a step behind Mother Nature, with deadly consequences."

The tragic July 4th flooding, where, in Kerr County alone, there were more than 90 confirmed fatalities, offers a sobering picture of how much can go wrong. "There were repeated flash flooding warnings in Kerr County, as rain moved in and the Guadalupe River surged at the start of the July 4 weekend," the Journal reports. "Those alerts never reached some of the campers and residents who lacked cellphone service, silenced notifications or didn’t have phones with them, and outdoor sirens were considered but never built."

Texas is not alone. Human errors during the January Los Angeles wildfires caused some text alerts to be delayed, with some even sent to the wrong areas. During Maui's deadly wildfires, cellphone networks failed, leaving some residents who would have received text warnings unaware and unable to seek safety in time.

Besides Mother Nature's stealth, human error and the unpredictability of first-time disasters, what else is going wrong? "The Federal Emergency Management Agency’s internet-based alert system has made it easier for local authorities to reach residents," they write. "But industry experts say some rural officials often lack the funding, expertise or permission from state authorities to push their own alerts through broadcasters and cellphones."

Too many alerts "can cause cellphone users to shut off notifications that become bothersome or irrelevant. A menu of warnings for floods, fires, missing children and more have caused 'alert fatigue' in some areas," the Journal reports. "The FCC is working on changes that would let authorities send muted or vibrate-only notifications in less-dire situations. Those changes won’t go into effect until 2028."
