From The Washington Post/Capital Weather Gang:
The rain from Harvey is in a class of its own. The storm has unloaded over 50 inches of rain east of Houston, the greatest amount ever recorded in the Lower 48 states from a single storm. And it’s still raining.
John Nielsen-Gammon, Texas state climatologist, said a rain gauge near Mont Belvieu at Cedar Bayou, about 40 miles east of Houston, had registered 51.9 inches of rain through late Tuesday afternoon. This total exceeds the previous record of 48 inches set during tropical cyclone Amelia in Medina, Texas in 1978.
