Historic, 1,000-year flood ‘like nothing South Carolina has ever seen’

SC flooding
October 2015SOUTH CAROLINA South Carolina’s record-smashing days of rain created a 1,000-year flood event that scientists may be studying for years, caused by a confluence of weather events. Some parts of the Charleston area received twice as much rain as Hurricane Hugo dropped in 1989, though mercifully without hurricane winds or a storm surge. Tropical moisture from Hurricane Joaquin and a second storm system was squeezed by two conflicting weather systems “into a narrow band of intense rainfall” funneled directly at South Carolina, according to AccuWeather. “I have never seen rainfall this intense, in this large of an area and during this short of a period in absence of direct impact from a tropical storm or hurricane,” said AccuWeather Chief Meteorologist Elliot Abrams. The storms resulted in what’s known as a 1,000-year flood, but scientists caution that doesn’t mean such flooding won’t be seen again during our lifetimes.
“You can, in theory, have a 1,000-year flood the very next day,” said Brenda Ekwurzel, senior climate scientist at the Union of Concerned Scientists. In a 100-year flood zone, there’s a 1 percent chance of flooding each year, and homeowners are typically required to have flood insurance. In a 1,000-year flood area, there’s a one-tenth of 1 percent yearly chance of flooding, but that doesn’t mean there will be 1,000 years between floods. “We certainly don’t have precipitation records going back 1,000 years,” said meteorologist Emily Timte of the National Weather Service, Charleston. The last rain event that comes close was in June 1973, when an unnamed tropical system dumped 16.56 inches on the Charleston area over four days.
During the first four days of this month, some parts of the Charleston area reported more than 2 feet of rain, and the 17.29 inches recorded at Charleston International Airport was enough to break all the records. “We beat the greatest one-day, two-day, three-day and four-day rainfalls,” Timte said. The heavy rains came during a time of unusually high tides, and with soil already saturated by heavy rain in late September. As a result, rainfall was less able to either soak into the ground or flow into the sea. In downtown Charleston, the harbor lapped over the seawall at The Battery, water came up through storm drains and the entire peninsula was closed to non-resident vehicles on Saturday.
Some neighborhoods in North Charleston and in suburban and rural areas were flooded so badly that residents were evacuated by emergency crews, in one case by helicopter. Upstate, streams became angry rivers, washing away roads and vehicles. Eleven deaths were reported in South Carolina and two in North Carolina, including at least seven drowning victims. “This was historic,” Ekwurzel said. “People will be studying this one.” –Post and Courier

    Did you ever think, even for a moment, that a nation that for decades spewed 25% of the Earth’s pollution into the air, might get paid back in spades? Too bad if you didn’t because it is happening now. I think the people of the Carolinas are reaping what their nation has sowed over decades!

    Today, 15Oct2015, in Southern California, our high deserts are flooding. In the nearby mountains Lake Hughes residents have been advised to shelter in place if safe evacuation is not available. Burn areas have strong mud flows. The only comment our local knuckle-head MSM weather readers are making about the convective activity is laughable. The funnel clouds may produce a tornado. ( I’m old. Have BZD-induced neurocognitive disorder. Have PTSD. I am blessed to have survived 3 cryptogenic strokes.I am blessed to have been shown the promises are true: A wonderful existence is awaiting us after death. I am blessed to remember my prayers, family, loved ones and you, Alvin. I hope I am politely blunt.)

    10/15/15: “Drivers describe long night on road as mudslides engulf nearly 200 vehicles”
    http://www.latimes.com/local/lanow/la-me-ln-5-freeway-remains-closed-more-thunderstorms-expected-20151016-story.html
    “Nearly 200 vehicles, including 75 tractor-trailers and two tour buses carrying passengers, were trapped on California 58 east of Tehachapi in up to 20 feet of mud and debris after torrential rains pummeled the area and forced drivers to flee.
    “Multiple mudslides hammered the highway just east of Sand Canyon between 4 p.m. and 5 p.m. as commuters traveled on Tehachapi Pass, a crossing in the Tehachapi Mountains in Kern County, said Ray Pruitt, spokesman for the Kern County Sheriff’s Department. Authorities said 115 vehicles, tractors-trailers and the tour buses were swallowed by several feet of mud.
    ““I have never seen slides like this,” Pruitt said…”
    “A series of heavy downpours Thursday pummeled northern Los Angeles County, causing mudslides and flash floods that inundated roads, trapped drivers and forced the closure of nearly 40 miles of the 5. Golf ball-sized hail pounded Lake Hughes and parts of Palmdale.”
