A series of thunderstorms triggered flooding in parts of east, central and southeast Charlotte on Tuesday evening, forcing the rescue of dozens of people from cars and homes in high waters.
The storms, which struck the Charlotte area during the height of the evening commute, also produced scattered reports of wind damage, including an unconfirmed report of a tornado in the Matthews-Mint Hill area.
Firefighters have used boats this evening to rescue stranded motorists and residents, and Charlotte officials have called in extra help to deal with flash flooding across the city.
A flood warning is in effect for central and eastern Mecklenburg County this evening.
The flooding washed out a portion of East Independence Boulevard near Briar Creek, and the inbound lanes remained closed at 10:15 p.m. Crews are trying to repair the road tonight, before the morning commute.
In addition, much of Freedom Park was under water at 10 p.m., as the Briar Creek poured over its banks.
The area remains under a tornado watch until midnight, although meteorologist Melissa Hurlbut at the Storm Prediction Center in Norman, Okla., said the storms have been weakening over the last hour or so.
“Little rotation and supercell structure has been observed recently,” Hurlbut said, adding that the loss of daytime heating is causing the storms to weaken.
However, new showers and storms continue to form this evening in the Greenville-Spartanburg area and move toward Charlotte. While those storms lack the power of the severe weather which hit the area earlier, they will dump more rain on already-soggy ground.
More than 2 inches of rain fell in two hours this evening at Charlotte/Douglas International Airport, and Doppler radar estimates indicate that between 3 and 4 inches might have fallen in east Charlotte, Matthews and Mint Hill.
An automated weather gauge in the Annecy neighborhood near Sam Newell and Rice roads in Matthews measured rainfall coming down at a pace of 3 inches per hour at 6 p.m. — moments before the storm knocked out power to the weather station.
Thousands of Duke Energy customers in Mecklenburg County lost power, but electricity had been restored to all but 2,000 customers by 9:30 p.m.
Additional severe weather is possible late Wednesday, forecasters say.
Capt. Mark Basnight of the Charlotte Fire Department said there were more than 70 flood-related incidents, with firefighters making about 50 rescues.
A number of people have been forced to flee their homes because of high water, including residents at the Doral Apartments on Monroe Road. The American Red Cross opened a shelter at East Mecklenburg High at 9 p.m. for anyone displaced by the storm.
The storms moved into the Charlotte area about 4:45 p.m. and intensified over the city. At 6:10 p.m., there were unconfirmed reports of a tornado touchdown near Interstate 485 between Matthews and Mint Hill.
The National Weather Service also reported several trees blown down at Thompson and Idlewild roads, along the Matthews-Mint Hill line.
While vivid lightning and gusty winds hit parts of the area, the heavy rain caused the biggest troubles. By 6:30 p.m., two to three inches had fallen in some areas and Charlotte firefighters began rescuing people trapped in cars or homes by high water.
Firefighters rescued more than a dozen people. Most calls were for motorists trapped in rising waters on major thoroughfares, but firefighters were also being called out to houses with power lines on them. There were no immediate reports of injuries.
East Independence Boulevard’s inbound lanes were closed for a time this evening at Albemarle Road, because the Briar Creek overflowed and flooded the roadway. Reports from crews dealing with the flooding indicated that several feet of water were on Independence Boulevard at one point.
Fire officials, who were bringing in additional resources from outlying parts of the city and from neighboring cities, encouraged people to stay home until the storm had passed. They asked residents to call 911 only if they have a life-threatening emergency, and be ready with information about the location and any injuries.
The first flooding calls came in around 5:20 in areas just west of uptown Charlotte, according to Capt. Rob Brisley, spokesman for the Charlotte Fire Department.
“As the system has moved from west to east,” Brisley said, “so did the calls for service.”
At the height of the storm, a motorist was trapped in a car at Buick Drive and Electra Lane. At least two people were trapped in a car on East Independence Boulevard near North Wendover Road. And a house had flooded on the 800 block of Crater Street, according to the Charlotte Fire Department.
The fire department was also pulling people from the water at Randolph and Wendover Roads, on Villa Court and near Third Street and Caswell.
“We’re asking people to get off the road and stay off the road now,” said fire department spokesman Capt. Mark Basnight.
Flooding was happening all over the city, but concentrated on Freedom Drive and Independence Boulevard near the end of rush hour.
Flooding has closed North Tryon Street near East 16th Street. Freedom Drive at Thrift Road and 9th Street between College and Brevard streets were also flooded, the Charlotte Fire Department is reporting.
The storms developed what meteorologists call a “training” process. That means thunderstorms continued to form and follow the same path. A weak and stalled frontal system across the Piedmont provided a focus for the thunderstorm develop.
Larry Gabric, chief meteorologist at the National Weather Service office in Greer, S.C., said the storms in Charlotte were training. “It’s just an east-west line through the city,” he said.
This trend of afternoon thunderstorms is expected to continue Wednesday and Friday — with a quiet Thursday forecast.
