Weather Underground midday recap for Wednesday,April 30,2014

More heavy rainfall and strong thunderstorms developed across the Southeast on Wednesday, while the Mid-Atlantic states saw severe thunderstorm development. A strong cold front continued moving across the Eastern states and continued pulling abundant moisture northward from the Gulf of Mexico. This allowed for heavy rainfall and flooding to continue across the Southeast, moving into the panhandle of Florida. Rainfall totals surpassed 5 inches in some locations across the Florida panhandle, with up to 9.52 inches of rain reported at Destin, Florida, and 7.14 inches reported at Panama City, Florida. These areas saw rainfall rates over 2 inches per hour, which caused major flood damage to roads, homes, and people. Please remember to stop and turn around when you come to a flooded road as it is always deeper than it looks.
At the same time, the northern side of this cold front stretched northward up the East Coast and also brought heavy rain and flooding to the Northeastern states and New England. There was a slight chance of severe thunderstorm development for parts of the Mid-Atlantic states, as moisture and energy continued to pour in from the south. Severe thunderstorms were expected to develop from South Carolina through Washington D.C., with large hail and strong damaging winds as the main threats, with a couple of tornadoes possible.

Groundwater Mining in California Creates Farming Hub but Land Sinks by Feet

By Michael Kuhne, AccuWeather.com Staff Writer
April 30,2014; 10:10PM,EDT
 
 
Mining groundwater for agricultural use in the San Joaquin Valley has not only created one of the most productive agricultural regions in the United States, but it has also simultaneously altered the surface of the land causing noticeable subsidence or sinking in the region, according to the U.S. Geological Survey.
"The maximum subsidence, near Mendota, was more than 28 feet," USGS reported, citing a 1970 comprehensive survey.
Overall subsidence has slowed since the 1970s due to reductions in the pumping and recovery of groundwater, as well as the use of other types of surface water irrigation.
"At least some of the groundwater is stored in between clay deposits and within clay deposits," AccuWeather.com Senior Meteorologist Ken Clark said. "When you extract the water, you take out the water surrounding (the) clay molecules, and this then allows the clay to compress. The more water you take out, the more compacting you have, and when that happens, the valley sinks."

According to U.S. Department of Agriculture National Agricultural Statistics Service Pacific Region Office Deputy Director Dave DeWalt, nearly 11.3 percent of the total value of U.S. agriculture commodities comes from California's prime agricultural region.
"So far (in 2014) we've only seen about one-third of the precipitation we normally would have," DeWalt said, referring to the Sacramento area.
With the drought continuing, food prices will spike.
"It is some of the richest farmland in the U.S.," Clark said. "There is talk that some commodities may not be feasible as they take a lot of water to grow. Such as almonds, a huge cash crop. It takes one gallon of water to make one almond."

According to Fresno State University Center for Irrigation Technology Consultant Sergeant Green, understanding the utilization of groundwater and the impacts on the Valley is not as simple as it seems.
"Water, crops and productivity are all dynamic," Green said.
The current crops using the most water in the region are almonds and alfalfa, he said.
"Almonds are a critical export that helps with balance of trade, and alfalfa is critical for the dairy industry which is a huge part of the agriculture economy in the Valley," Green said. "The three top agricultural commodities are almonds, grapes and dairy products."
The San Joaquin Valley is part of the Central Valley of California, includes the Sacramento
Valley and the Sacramento-San Joaquin Delta. This area produces about a quarter of the nation's table food on only 1 percent of the country's farmland, USGS reports.

"Groundwater in the north of the Valley is relatively stable, the south Valley (Fresno south to Bakersfield) has declined consistently," Green said. "Old pre-1960s subsidence stopped until surface water supplies from the Bay-Delta were cut back starting in the mid-'90s."
According to the USGS, land subsidence in the Valley was first recorded in 1945 by Engineering Consultant I.H. Althouse.
"The history of land subsidence in the San Joaquin Valley is integrally linked to the development of agriculture and the availability of water for irrigation," the USGS reported. "Further agricultural development without accompanying subsidence is dependent on the continued availability of surface water, which is subject to uncertainties due to climatic variability and pending regulatory decisions."
The 10,000-square-mile area making up the Valley floor is comprised of continental sediments and includes fine-grained, stream and lake deposits, which are susceptible to compaction, the USGS reported.
"When farmers and ranchers have to rely on groundwater instead of stored above ground water during extended droughts, more water is being extracted than can be returned," Clark said. "Once the clay is compacted, there is no way to ‘unpack' it."
According to AccuWeather.com Meteorologist Randy Adkins Jr., California has received less than their average rainfall for several years consecutively.
"It's been a multi-year drought," he said.
AccuWeather.com Meteorologist Jim Andrews said the last three winter rainy seasons (October to April) were drier than normal, the last winter being driest of the three. Cumulative rainfall (including melted snow) is as little as one half of normal amount for the three rainy seasons collectively, Andrews said.
"Fresno has only seen 55 percent of their normal for those three seasons," he said. "That's around 16 inches of rain less than normal."
Andrews added that the Sacramento region has been doused with only 68 percent of their normal rainfall of 54.5 inches.
Green said rainfall is not adequate to recharge the groundwater, adding it needs to be stored, applied or recharged in specific areas that allow the capability to add more water than what is being extracted at those locations.
In addition, new developments in irrigation are being utilized currently, but the amount of water needed will continue to be based on what crops are in demand, Green said.
"Precision irrigation systems are now widespread and continuing to increase rapidly, but don't always mean less water is used," he said. "Crop requirements determine total demand, and permanent crops such as almonds have been increasing for some time."

Los Angeles: Heat Wave Induces Fire Threat Through Late Week

By Kristen Rodman, AccuWeather.com Staff Writer
April 30,2014; 10:50PM,EDT
 
 
With record-challenging heat building in the city through late week, the fire threat will increase in Southern California this week.
As temperatures are expected to reach the mid-90s both Wednesday and Thursday, the city will have the chance to break its old record of 89 degrees set in 1929.

However, the heat combined with the gusty Santa Ana winds will raise the fire danger from Los Angeles down through San Diego this week.
"The combination of very low humidity, heat, sunshine and wind can cause any fire that gets started to spread rapidly through dry brush and potentially into populated areas," Clark said.

Heat, Fire Threat Build in California Through Thursday

On Wednesday afternoon, a fire broke out in Day Canyon in the Etiwanda Preserve, located just north of Rancho Cucamonga near Los Angeles. Residents in the vicinity of the fire were evacuated Wednesday. As of Wednesday afternoon, the fire burnt nearly 200 acres.
By Wednesday evening, the fire had grown to more than 1000 acres.

Through Thursday, the Santa Ana winds are expected to gust up to between 40 and 70 mph, continuing the fire threat for the region.
People are strongly urged to use extra caution when operating machinery or equipment that can spark a fire.
While the heat wave is expected to diminish over the weekend, temperatures will remain in the 90s on Friday.

Smoke Plume Engulfs Virginia Skies After Oil Fire, Train Derailment

By Michael Kuhne, AccuWeather.com Staff Writer
April 30,2014; 10:41PM,EDT
 
 
Dark clouds of thick, black smoke belted with flames soared into the sky above downtown Lynchburg, Va., Wednesday afternoon as authorities evacuated several buildings in the area, The Associated Press reported.
"Lynchburg officials are reporting that between 12 and 14 CSX tanker cars carrying crude oil were involved in the train derailment in downtown Lynchburg causing extensive flames and dense black smoke," city officials reported.
The train was traveling from Chicago to Virginia when the derailment occurred, CSX said in a news release. Three rail cars were on fire but have since been extinguished.
At around 2 p.m. when the incident occurred, dense fog hovered throughout the area, which reduced visibility to under a mile, AccuWeather.com Meteorologist Carl Erickson said.
There have been no injuries reported at this time, according to the city's news release.
Residents were allowed to return to their homes in the evacuated area of Commerce and Jefferson streets, the city said.
The fire was reported along the James River. No contamination of drinking water due to the oil spill has been reported.
Erickson said storms will approach the region into the evening hours.
"There will be some showers and, as with any storm, you can have some gusty winds move through," he said, citing trouble in firefighting efforts and spread of the fire.
Erickson said after midnight the storms should begin to taper off.

Firefighters and rescue workers work along the tracks where several CSX tanker cars carrying crude oil derailed and caught fire along the James River near downtown in Lynchburg, Va., Wednesday, April 30, 2014. Nearby buildings were evacuated for a time, but officials said there were no injuries and the city on its website and Twitter said firefighters on the scene made the decision to let the fire burn out.
