Example Input: Mexico City, Mexico (CNN) -- What was Hurricane Karl weakened Friday to a tropical storm after making landfall, but the heavy rain it spawned could still cause mudslides and flash floods in the Mexican interior, forecasters said. Karl was downgraded after coming ashore as a Category 3 hurricane about 10 miles (15 kilometers) north of Veracruz, Mexico, CNN's satellite and radar estimates showed. The storm is forecast to weaken to a tropical depression later Friday or Saturday and dissipate over the mountains of Mexico on Sunday, the U.S. National Hurricane Center said Friday evening. It added the Mexican government has discontinued all coastal watches and warnings. The storm delivered torrents of rain and fierce winds several hours before it hit land around 11:30 a.m. (12:30 p.m. ET). Photographs sent to CNN's iReport by Ricardo Arcaraz, who lives in Veracruz, showed heavy rain and trees on top of power lines. He reported widespread outages. Maximum sustained winds later weakened to around 70 mph (115 kph) with higher gusts, according to the Hurricane Center. Karl, located about 75 miles (115 kilometers) east of Puebla Mexico, was moving west-southwest at about 9 mph (15 kph), it said. Satellite images and surface observations from Mexico suggest Karl is weakening rapidly as it passes through steep mountains, the Hurricane Center added. High winds remain a threat, though forecasters said they will likely weaken too in the coming days. The homes of at least 3,000 families in central Mexico were damaged, the state-run Notimex news agency reported. "Tropical storm force winds are occurring in a small area near the center. These winds will continue to spread inland along the track of the center tonight but should decrease rapidly as Karl weakens," the Hurricane Center said. Potentially dangerous rain also was forecast. "Karl is expected to produce rainfall accumulations of 5 to 10 inches across portions of south-central Mexico, with isolated amounts of 15 inches possible in the mountains," the center said. "These rains could cause life-threatening flash floods and mudslides." Within the past day or so, some 8 inches of rain has fallen in Veracruz, according to CNN meteorologist Brandon Miller. Some local flooding was already reported, the Mexican Interior Ministry said. Officials closed some roads and urged evacuations for large, low-lying areas in Veracruz. Mexico's National System for Civil Protection issued a red alert, the highest level, for central and southern Veracruz. An orange alert was in place for northern Veracruz and the states of Hidalgo, Tlaxcala and Puebla. A yellow alert was issued for the states of Tamaulipas, San Luis Potosi and Oaxaca. Mexican President Felipe Calderon also sent a warning Friday morning on his Twitter account. "An alert for Hurricane Karl in the nation's central states," it said, adding that Karl "could convert to a Category 4. It will enter through Veracruz around midday." Texas could be spared any major problems because a storm surge occurs only near the landfall location, said CNN meteorologist Sean Morris. Coastal flood advisories have been issued for south Texas, which means forecasters expect a small amount of coastal flooding but nothing serious, Morris said. A larger threat to south Texas will come from several inches of rain that could cause flooding and mudslides. The area could see as much as 4 inches by Sunday, with isolated amounts of up to 6 inches in far southern Texas. CNN meteorologists Brandon Miller and Mari Ramos contributed to this report.

Example Input: Washington (CNN) -- If the threat of underwear bombs became known last Christmas, why did airport screeners only recently begin aggressively checking for them? The answer is two-fold, Transportation Security Administration Director John Pistole told reporters Tuesday. First, the lack of a permanent leader at the TSA hindered change, he said. Secondly, the agency needed time to train screeners on the new pat-down protocols. The threat of hidden bombs became instantly clear on December 25, 2009, Pistole said, when authorities arrested Umar Farouk AbdulMutallab, a Nigerian man, after his failed attempt to ignite his hidden explosive on a flight from Amsterdam to Detroit, Michigan. TSA officials immediately started looking at what they needed to do to modify technology or pat downs to detect the bombs, he said. But at that time, the top job at TSA was filled by a career official. The White House delayed nominating a TSA chief and then White House and Congressional Republicans feuded for a year over nominees. Much of the debate centered on whether the nominees supported unionization of airport screeners. Two of President Obama's nominees withdrew from consideration. "Frankly it just came down to the fact there was not a presidentially appointed, Senate-confirmed administrator in place until I was confirmed at the end of June to make a really significant decision like that, that would have impact on a number of people," Pistole said. "That was a big part of it." Pistole was sworn in as administrator in July and soon thereafter made the decision to go through "enhanced pat downs." Training time accounts for the rest of the delay, as the TSA quietly began pilot programs in Boston, Massachusetts, and Las Vegas, Nevada, in August, and rolled the program out nationwide in early November. Pistole consistently has said it was his decision to implement enhanced pat downs. He said he opted not to publicize them in advance because he felt to do so would be to give a "roadmap" to would-be terrorists. Implementation of the pat downs was further delayed because time was needed to train screeners on the new protocols, he said. Those protocols are considered sensitive security information, and have not been shared with the public. But Pistole said protocols do not allow for screeners to grope passengers. Pistole said some passenger descriptions of the procedures are "so wildly outside the standard operating protocols that it just absolutely should not be happening. If it is, then we'll take appropriate action." "If we receive any complaints from a passenger about something happening, then we immediately follow up both with that passenger and with our security officers," he said. Most airport checkpoints have closed circuit television systems, which help investigators find out what happened, he said. Videotape helped dispel one passenger's complaint that she was handcuffed to a chair and mistreated, he said. "If there's a security officer that did something that's not appropriate, then we take appropriate action. I just want to make sure that I have all the facts," Pistole said.
Example Output: The failed underwear bombing last Christmas raised the threat of bombs hidden in clothes .
Pistole says after that, the pat-down program was delayed by two factors .
The TSA lacked a permanent leader until July .
Extensive training also was required before implementation of the program, he says .

Example Input: In 2010 alone, there were roughly 1,100 attacks on U.S. fuel convoys. This has cost the men and women of our armed forces dearly. Military officials recently reported  that more than 3,000 uniformed soldiers and contractors died while protecting such missions in Iraq from 2003 to 2007.  But new Pentagon initiatives could dramatically reduce our battlefield fuel demand through the use of new clean energy technologies, helping save lives and stretch ever-scarce defense dollars. The U.S. Department of Defense is one of the world's largest institutional energy consumers. Using more than 300,000 barrels of oil daily, the U.S. military consumes more petroleum products than three-quarters of the countries in the world. In fiscal year 2008, energy cost the department about $17.9 billion. Leaders in the Pentagon, though, are up to the challenge. The Defense Department played a key role in the development of the Internet, semiconductors and modern satellite-based navigation, used by virtually anyone with a smartphone. Now, as detailed in a recent report by the Pew Charitable Trusts, its efforts to improve vehicle efficiency and use advanced biofuels could similarly lead the way for countless U.S. businesses seeking a foothold in the burgeoning global clean energy economy. Building on the work of an expert panel convened by the Defense Science Board, the Pentagon has called for a new technology development strategy aimed at reducing risk to soldiers and enhancing our nation's overall long-term energy security. The department considers this one of its top strategic imperatives. In keeping with this plan, the military has set a target of obtaining 25% of its energy from renewable sources by 2025, with 450 renewable energy projects already functioning. For example, the Navy will soon test a hybrid electric drive system for the USS Truxtun, a guided missile destroyer, which will save 8,500 barrels of fuel annually. The Air Force made history last year with the first flight of a biomass-powered aircraft, the A-10C Thunderbolt II. And the Army has insulated roughly 9 million square feet of bases in Iraq and Afghanistan, reducing energy consumption by 77,000 gallons per day. With more than 500,000 buildings and structures at major installations around the world, the Defense Department manages three times the square footage operated by Walmart. Since 1985, it has reduced its facility energy consumption by more than 30%. The Army's "Net Zero" program offers another case in point. The project aims to have select installations each produce as much as they consume in energy, water or waste by 2020. Fort Carson and Fort Bliss, to name just two, will become Net Zero in all three areas. Combined, these efforts could have a huge impact on U.S. operational security. On average, each deployed soldier requires 22 gallons of fuel per day. In fact, in Afghanistan alone, tens of millions of gallons of fuel must be delivered each month. Yet, according to the U.S. Army, there is roughly one casualty for every 46 ground resupply convoys in Afghanistan. So reducing our reliance on oil could keep countless troops out of harm's way. This Pentagon initiative could also act as a catalyst for our nation's growing clean energy economy. According to Pew's report, the military's sizable purchasing power could provide a crucial difference in helping technologies make the transition from the labs to the marketplace. In the process, badly needed jobs and manufacturing opportunities in the private sector also could be created across the nation. The past decade has presented great challenges to our armed forces. They have responded with creativity, tenacity and courage. The Pentagon has been charged with managing two wars, helping establish more robust homeland security measures and responding to worldwide humanitarian emergencies. Throughout these trying times, however, the military also has looked inside its own operations and developed a sound strategy to enhance America's security and lessen our dependence on foreign fuels. Congress and the White House should match that effort and aid this endeavor to save American lives, money and energy.
