This may end up being one of the worst flood disasters in U.S. history.
Harvey has stalled inland over southeast Texas, resulting in catastrophic, record flooding.
Periods of torrential rain will continue over parts of Texas the next several days with more flooding likely.
Parts of southeast Houston saw more than two feet of rain in 24 hours.
The flooding has rivaled what was observed during Tropical Storm Allison in 2001 in some locations.
Isolated rainfall totals from Harvey could be up to 50 inches by later this week.
