A high pressure system swept across Warren County Sunday and this morning, dumping more rain than Tropical Storm Isaac and causing mudslides and flash flooding.

Vicksburg Water Treatment plant put the 24-hour rainfall, as of 8 a.m., at 3.96 inches.

During Isaac the highest 24-hour total was 3.67 inches.

The rainfall for the past 24 hours brought the city’s precipitation for the year to 50.83 inches, compared with an average of 39.82.

The rain was caused by a high-pressure system picking up moisture from the Gulf of Mexico, said National Weather Service meteorologist Marc McAllister.

“We won’t worry about lack of rain anytime in the future,” McAllister said. “There are people around the country screaming for rain because of the drought, but we’re in pretty good shape down here.”

The moist soil in the area along North Washington Street wasn’t able to withstand the downpour. City crews were clearing a half-mile area north of Spouts Springs Road this morning, and traffic was slowed to one lane, Police Chief Walter Armstrong said.

On Thompson Lake Road, about 2½ miles north of Spouts Springs, a culvert failed near a natural gas distribution substation, and the north side of the gravel road washed away, leaving a ravine about 3 feet deep. The road was rutted but passable this morning.

City street superintendent Skipper Whittington said a tree fell on Great Street about 7 p.m. Sunday, blocking the street, breaking a utility pole and pulling power lines down on Harrison Street.

Entergy customer service representative Tammy Rankin said about 300 customers in that area lost electricity, but power was restored Sunday night.

Whittington said flash flooding affected North Washington Street at Spouts Bayou Road, Sky Farm Avenue and Halls Ferry Road at Coccaro’s Alley in Marcus Bottom Sunday.

Another area that flooded was Stadium Drive. Grady Edwards, 1001 Stadium Drive, said this morning the area “looks like a little lake.”

Armstrong said police investigated 11 accidents — two with injuries — scattered across the city from Saturday morning until about 9:30 a.m. today.

He said the extent of the injuries in the accidents was unknown.

Rain was expected to let up tonight, but dreary conditions will continue into Tuesday, McAllister said.

The rest of the week should be cool and clear with highs in the 70s and lows near 50, he said.
