Towns in Missouri, central Illinois and at least four other Midwestern states are under a flood warning, as heavy spring rains swell the Mississippi and other rivers to dangerously high crests. In some areas, rivers have already hit record flood levels.
In places where residents have been forced to evacuate their homes, the American Red Cross has set up shelters at schools and other facilities.
A large storm system moving through the center of the country, has already caused major flooding in Chicago and is threatening to bring severe weather to the Tennessee Valley all the way to the Gulf Coast, tonight.
Just a stone's throw from two of Los Angeles' busiest freeways lies the Sepulveda Basin Wildlife Reserve, a unique spot in an urban jungle.
The northern portion of the reserve is adorned with 30-foot-tall cottonwood trees, spots of coyote bush and other plants. Native plants cover 50 percent of the nature spot, says Kris Ohlenkamp with the San Fernando Valley Audubon Society.
"On the other side it was significantly more than that," he says.
