The Federal Communications Commission (FCC) and the Federal Emergency Management Agency (FEMA) are conducting the first ever Wireless Emergency Alert (WEA) test. Here's what you need to know.

In Colorado, the test will be on Wednesday, October 3 at 12:18 p.m. Mountain Daylight Time (MDT). For the wireless test, also called the 'Presidential Alert', cell towers will send the test for about 30 minutes.

Only cell phones within range of a cell tower who's wireless provider participates in the WEA program will receive the message. FEMA estimates 75% of people in the US will be within range of a cell tower of the more than 100 providers who participate in the program.

The 'Presidential Alert' is one of three alerts sent through the WEA system. The other two are Amber Alerts and dangerous weather conditions.

The message you receive on your phone will say "Presidential Alert: This is a test of the National Wireless Emergency Alert System. No action is needed."

The wireless test is being done along with a national EAS test which will be sent at 12:20 p.m. MDT. Both tests are part of the International Public Alert System (IPAWS).
