More than a foot of rain could fall on the southern United States over the next week, with some spots on the Gulf Coast seeing more than ten inches of rain yesterday alone. On a scale from "grab an umbrella" to "Jim Cantore's comin' to town," this week will be a solid "build yourself an ark."

Between 10 and 15 inches of rain fell along the northern Gulf Coast in less than 24 hours yesterday, resulting in catastrophic flash flooding in cities along Interstate 10 from Mobile, Alabama to Pensacola, Florida. The National Weather Service issued a "flash flood emergency" for much of the area as both waterways and infrastructure were overwhelmed by the copious amounts of rain.
