Severe Weather Awareness Week: Flooding in the Lowcountry

Weather News

CHARLESTON, SC (WCBD) – Flooding is something we know all too well here in the Lowcountry; it doesn’t take much for us to see some sort of flooding. 

“Turn around don’t drown” is a phrase used a lot when flooding is in the forecast. 

Flooding is the number one cause of death associated with thunderstorms each year with more than 90 fatalities yearly. 

That is why tell people not to drive into flooded roadway because it is impossible to determine how deep the flooding may be and it doesn’t take much to cause damage.

In fact, it only takes about 6-inches of water to stall a car and only 12-inches of water to move the car.

When the word ‘flash’ is used before the flood watch/warning, it refers to the amount of time before that flooding is expected.

Flash means that flooding is expected within a few hours, this is usually used when excessive rainfall is expected or a dam/levee have failed. 

Standard flood watches/warnings are issued when flooding is happening slowly, greater than 6 hours.

Flood waters can take a few hours to a few days to recede.
