Residents of the southern United States are facing more severe weather Tuesday, after two days of tornadoes flattened neighborhoods and killed at least 30 people.
The deaths occurred across six states, from Oklahoma to Alabama. The brutal storm system hit hardest in Arkansas and Mississippi, downing trees and power lines and reducing homes and businesses to rubble.
Tens of thousands of people were without power Tuesday, as rescuers continued to search for survivors.
The National Weather Service says the Gulf Coast states of Mississippi, Alabama and Louisiana remain under threat into Tuesday night. Tornadoes and damaging winds are likely, along with large hail, some the size of a baseball.
President Barack Obama offered condolences to the storms' victims Monday during a visit to the Philippines, promising the government will help them recover and rebuild.
The storm system is hitting around the third anniversary of one of the worst tornado outbreaks in U.S. history, which killed more than 300 people and included some 300 reported tornadoes across the nation's southeast.
