BEAUMONT, Texas — Texas Division of Emergency Management meteorologists have issued a rare high flood risk for Wednesday for portions of Liberty, Harris, Chambers, Brrazoria and Galveston counties. 

"High risks for flash flooding are rarely issued and often see flood fatalities and millions of dollars in damages," TDEM meteorologist John Honoré tweeted Wednesday morning. 

A high flood risk means severe, widespread flash flooding is expected. Ares that don't normally experience flash flooding could. Lives and property are in greater danger, according to the National Weather Service. 

Matagorda County, Texas, has seen rain bands produce up to 5 inches of rain per hour Wednesday morning.

Moderate flood risk means numerous flash floods are likely, according to the NWS. Many streams may flood, potentially affecting larger rivers and bayous.
