Thirty-mile-per-hour wind gusts preceded a thunderstorm cell that dumped more than an inch of rain, according to data suppled by New Orleans Lakefront Airport.

The rain pummeled New Orleans for about an hour, causing flash flooding all throughout the area, especially Lakeview where many streets completely flooded, and in some cases submerged vehicles.

Canal Boulevard underpass near the railroad tracks went completely underwater, according to tweets posted on Twitter in the wake of the storm.
