Cannon County Emergency Management Agency will be closely watching this week as the large amount of rain comes into Cannon County, Director Roy Sullivan said Monday.

"Most weather patterns affect only portions at a time but this weather event is concerning because it will encompass the entire county with predicted total amounts of up to 10 inches by Sunday night," Sullivan said.

Rain totals over 5 inches in a couple of hours usually always results in flash flooding in Cannon County, washing away back roads and driveways, sometimes making them unpassable, Sullivan added.

"The Cannon County Road Dept. has always done a fantastic job in quickly repairing flood damage and getting traffic going. This event is of concern because there is the potential for widespread damage, so logistically speaking, it will take longer to get the repairs completed," Sullivan advised.

Sullivan said according to, they advise when driving during periods of heaving rain or flooding:

"Unless you're driving a high-riding 4x4, the maximum depth most experts advise you drive a standard car through is slightly less than 4 inches. Modern cars are generally water-tight so they can start to float when driven through water that's only 12 inches deep.

"If you can't see the roadway due to flowing water, don't attempt to drive through it. Even if the water doesn't seem that deep, it can be hiding portions of the roadway or driveway that have been washed away."

Cannon County has had several flood related deaths in years past with three flood fatalities on Auburntown Rd. in 2002, Sullivan said. Two years ago saw a flood rescue in the Mooretown Community when someone tried to cross a flooded driveway.

"The Auburntown and Gassaway Communities see flooding issues fairly regularly and Cannon EMA will do ongoing damage assessment as the weather progresses later the next 7 days," he added.

"This wet weather will progress over the next 7 days so the rain fall totals will be over time and not all at once, so that should make a difference in the flooding we will receive," he added.

Here is the NWS prediction as of this morning:


TODAY: Dry and cool.

TUESDAY AFTERNOON TO EARLY THURSDAY MORNING: First round of heavy rain expected with forecast rainfall of 2" to 4"

REST OF THURSDAY INTO THURSDAY NIGHT: Light rain of 1/2" or less

FRIDAY TO SUNDAY: Several rounds of heavy rainfall likely (exact timing uncertain), with additional forecast rainfall of 3" to 4" before rain ends by Sunday night


IMPACTS: With grounds already saturated and rivers, creeks and streams running high, this additional rainfall could lead to significant flooding over the next week.
