Flood water was rushing into the first floor of the KHOU 11 building in Houston Sunday morning, forcing an evacuation of the building.

Buffalo Bayou, across the street from the station just outside downtown, was one of many locations seeing immense flooding as Tropical Storm Harvey dumped staggering amounts of rain on the Greater Houston area.

Broadcaster Len Cannon was live on air when a puddle of water started crawling toward the anchor desk during extended coverage Sunday morning.

The broadcast, along with newsroom operations, were moved to a second-floor conference room.

Later Sunday morning, the first-floor newsroom was completely flooded and water was rushing into the station's front door.

According to KHOU reporter Janelle Bludau, the station’s building last flooded during Tropical Storm Allison in 2001.

Allison left Harris County with 22 fatalities and more than $5 billion in property damage in its wake, according to a previous KHOU report.

KHOU has floodgates around its building.
