Double Rainbow and Mammatus Clouds Hang Over Houston

A spectacular double rainbow dazzled Houstonians on May 17, as thunderstorms brought heavy rain to southeastern Texas and parts of Louisiana.

Video filmed by Paul Medica shows the arcs and a sky full of mammatus clouds at sunset over Houston on Monday evening.

On Tuesday the National Weather Service issued a flash flood warning for much of southeast Texas through Thursday, warning of rainfall totals up to eight inches. Credit: Paul Medica via Storyful
