One day before the United States conducts a major test of its emergency alert communications network, Russia will hold drills in the event of a major nuclear attack. 

On Wednesday, the United States Federal Emergency Management Agency will test its Integrated Public Alert and Warning System. 

According to The Hill, the test will occur at about 2:20 p.m. Eastern Time unless bad weather postpones it for a week. This will mark only the second time FEMA has tested its national alert system for cell phones, which will be accompanied by a test through radios and TVs.
