Harvey is now one for the history books.

The storm battering Houston broke the US record for rainfall from a tropical system Tuesday, according to the National Weather Service

A weather station southeast of Houston reported 49.32 inches of rain as of the morning — smashing the previous record of 48 inches set in 1978 in Medina, Texas, by Tropical Storm Amelia.

“It’s a big deal,” said meteorologist Marc Chenard of the weather service’s Weather Prediction Center.

More than a dozen other spots around Houston have recorded more than 40 inches of rain.
