On alert

Vice President Joe Biden says authorities on alert for a Sept. 11 anniversary terror threat are more worried about "a lone actor" with a bomb than an extremely complicated plot like the airliner attacks on the twin towers and the Pentagon.

Biden says new information about a possible plot for a car bombing in Washington or New York comes from a "credible source" but isn't confirmed. Biden says there's "no certitude." He says the government is doing everything possible to guard against any attack, and "all hands are on deck."

Speaking Friday on NBC's "Today" show, Biden advised residents of Washington and New York to "continue your life as normal" and remain vigilant and report any suspicious activity to law enforcers.

Fairfax flooded

High water forced authorities to close the Capital Beltway in both directions Thursday evening where it crosses a stream called Cameron Run and at another location in Fairfax County. National Weather Service meteorologist Heather Sheffield said the northern Virginia area had gotten 13 inches of rain in the past two days. Two people, including a 12-year-old boy, died Thursday in rising floodwaters in Fairfax County as the remnants of Tropical Storm Lee sent torrential rains streaming into northern Virginia, officials said.

Wind farms funded

Two projects in Virginia aimed at speeding the development of offshore wind farms are getting federal funding. The U.S. Department of Energy awarded $4.1 million to Alstom Power Inc. and $500,000 to Dominion. Both companies are based in Richmond. Alstom Power will use the funding to develop an advanced turbine control system, while Dominion will analyze a hypothetical 600-megawatt offshore wind project for performance and cost-of-energy estimates.

Sept. 11 commemoration

Arlington County, home to the Pentagon, will host several events Saturday to commemorate the 10th anniversary of the Sept. 11 attacks. A commemorative event Saturday night at 7:30 p.m. at the Air Force Memorial, which overlooks the Pentagon, will feature musical performances by the Air Force Band Brass Quintet Ensemble and Wakefield High School's a cappella choir. The county also is sponsoring a 5K run Saturday that benefits a variety of charities related to Sept. 11 and military families.

Serial slasher

Police are seeking 40-year-old Johnny Guillen Pimentel who has been charged in a series of slashings of young women in Fairfax County in recent months. Police believe he may have left the area. Authorities believe he may be driving a blue 2003 Honda Civic with Virginia tag KLX2689. Since February, nine women have reported being slashed from behind at malls and retail outlets in the county. None suffered serious injuries.

Attorneys booted

A prosecutor and a defense attorney have both been removed from a child abuse case in Caroline County. According to The Free Lance-Star Circuit Judge Joseph J. Ellis removed Commonwealth's Attorney Tony Spence and defense attorney John LaFratta on Wednesday. Ellis said he's not sure the defendant can get a fair trial if Spence and LaFratta remain due to personal animosity between them.

Dead dolphin

A bottlenose dolphin that was stranded in a creek near the Chesapeake Bay has been found dead. The Virginia Aquarium and Marine Science Center's stranding team found the dolphin's carcass Friday in the Diascund Creek off the Chickahominy River. The team will perform a necropsy on the dolphin. Higher waters from Hurricane Irene might have pushed the 6-foot-to-8-foot-long male dolphin into the freshwater river.
