Storms Expected To Continue Flooding Southern States For Days

From Arizona to New Mexico deserts and Louisiana swamps, a high pressure system is dumping rain in the South, triggering mass flooding.

Across massive swaths of the South, heavy rains are prompting flooding and flash flooding.

From the high deserts of Arizona and New Mexico to the swamps of Louisiana, storms are dumping inches of rain, on ground in no shape to absorb all that water.

"We're going for periods of a long time without rainfall, and then bang — we'll get periods of very intense rainfall and flooding," said David Feldman, professor of urban planning and public policy at the University of California Irvine.
