Harvey broke the record for wettest tropical storm in U.S. history.
National Weather Service reported that Harvey has the biggest accumulation of rainfall ever recorded in the United States, for a single tropical storm.
The Service recorded more than 50 inches of total rainfall at a site southeast of Houston, higher that the previous record if 48 inches.
Harvey has now set a preliminary record, surpassing 50 inches for the greatest amount of measured single-storm rainfall for the continental US. Additional rainfall accumulations of 6 to 12 inches are expected to the north and east of Houston from far east Texas into southwestern Louisiana. This is producing devastating flooding. Numerous Flash Flood Warnings are in effect.
