Over just two hours, the Guadalupe River at Comfort, Texas, rose from hip-height to three stories tall, sending water weighing as much as the Empire State building downstream roughly every minute it remained at its crest. The force of floodwater is often more powerful and surprising than people imagine.

New satellite images released from Maxar Technologies show the destruction of the flash floods that have resulted in the deaths of more than 100 people over the July 4 weekend.Local authorities estimate around 160 people are still missing as Thursday marks the seventh day of the search for victims.
