Emergency Alerts are on the Rise in the Philly Region. Here’s What You Need to Know

If you think you’re receiving more emergency notifications on your mobile phone, television, or radio, you’re not imagining it.

Tornado and severe thunderstorm warnings in the Philadelphia area have been increasing since 2019, according to the National Weather Service. That’s partly because of increased tropical systems, and also because of improved technology that better detects severe weather such as tornadoes.

If you live in Philadelphia, you may have received several notifications this summer about emergencies — from the chemical spill in the Delaware River to the I-95 bridge collapse. The city’s Office of Emergency Management has also lowered its threshold for notifying residents about building fires — from three-alarm fires to two alarms.
