Flash-flooding from overnight and early-morning rains closed one county road and caused an hour-long power outage in the city, officials said.

The rain comes on the heels of an all-day downpour Monday.

About 843 buildings downtown and along Clay Street lost electricity around 5:30 a.m., said Entergy customer service manager Don Arnold. As of 10 a.m., four customers were without power.

Places without electricity included Horizon Casino on Mulberry Street and the Vicksburg Warren School District office on Mission 66.

&#8220We were just fortunate that the downpour was just before we ran the buses,” said VWSD Superintendent James Price, adding that the rain had little effect on routes this morning.

About 2 inches of water did, however, enter a secondary gym at Warren Central High School. The rainfall caused a drain to overflow and water came in through a doorway, Price said.

Construction was being done there and the floor had been stripped down to the concrete, Price said, so damage there was minimal.

Downtown, a retaining wall near Monroe and Jackson streets between the Warren County Board of Supervisors office and the Vicksburg Municipal Auditorium that had collapsed during Monday’s rains further deteriorated. Also, the Vicksburg Wastewater Treatment Plant on Rifle Range Road was flooded.

A special meeting has been scheduled by the Vicksburg Board of Mayor and Aldermen for 2 p.m. today to deal with both issues.

Sgt. Beverly Prentiss of the Vicksburg Police Department said flooding was reported in the 2900 block of Drummond Street, the 300 and 400 blocks Farmer Street, the 2400 block of Grove Street, Pemberton Square Boulevard near Orme Drive and the 800 block of South National Street.

High water was also reported at North Frontage Road and Indiana Avenue.

&#8220People need to be cautious,” Prentiss said. &#8220If they see a whole lot of water or mud, just don’t go through there.”

In the county, the intersection of Paxton Road and Old Highway 27 was shut down.

&#8220It was underwater for a period of time,” and had to be barricaded by deputies, said Sheriff Martin Pace. &#8220That particular intersection drains off quickly as the rain slacks off.”

Water also affected travel on other county roads, Pace said, but they were passable.

Monday’s rains brought more than 6 inches of water to the area. Low-lying streets flooded, a mudslide blocked U.S. 61 North and as many as 265 Entergy customers lost power.

National Weather Service historical data says 6.1 inches is average for an entire March in Vicksburg and only one month, December, has a higher monthly average at 6.4 inches. Normal for October is 3.8 inches. This week’s rain comes after an unusually dry summer.

Showers began falling around 7 p.m Wednesday night, with especially heavy periods at midnight and about 5:30 this morning, National Weather Service data showed.

At 6 this morning, the latest measurement available from the Vicksburg Water Treatment Plant, 1.16 inches had fallen.

No rain was recorded Tuesday.

Today’s rain was forecast to end this afternoon.
