When storms roll in, water rushes downhill fast, gaining speed and force as it moves — often with deadly results.

KERR COUNTY, Texas – The Hill Country flood, marked by unprecedented rainfall and unfortunate timing, has become one of the deadliest floods in Texas history, with its swift waters catching many off guard in the dead of night.

Five people died in Central Texas floods in October, and then the rain kept coming for the next two months. Catastrophic flooding devastated the Hill Country, and statewide at least 180 Texans died because of the countless overflowing rivers and creeks.
