MAYFLOWER, Ark. -- Auctioneers preparing for a backyard estate sale Saturday morning made an explosive discovery among the china and other items up for bid -- a suitcase full of military-grade explosives.

Auctioneers got the suitcase open just before the sale on Saturday and found three blocks of military-grade C-4 plastic explosive, two tubes of a similar plastic explosive, a blasting cap and some dynamite.

Workers quickly called 911. The Conway Fire Department's bomb squad put the aging explosives inside a special container and drove them out to an isolated spot to destroy them, district chief Jon McMahon told the Log Cabin Democrat newspaper.

The auction went on as planned.

Faulkner County sheriff's office Maj. Andy Shock said the explosives had deteriorated over time and likely were at least 15 years old. Shock said that age put the C-4 at the outer limits of its shelf life, meaning the explosives were unstable and even more dangerous.

The items at the estate sale belonged to a U.S. Navy veteran who recently died, Shock said. Deputies continued to investigate the incident, but charges weren't likely as the presumed owner of the explosives is dead, he said.

MIAMI -- Flooding left behind by Tropical Storm Fay forced residents in parts of northern Florida out of their homes Sunday, while the storm's remnants were forecast to dump several inches of rain on at least four other states.

Officials ferried people by boat from homes in DeBary, 25 miles north of Orlando, where some streets were under 4 feet of water, and flooded neighborhoods in and around Tallahassee.

"The water is very deep. It's already at everybody's door," said Debra Galloway, who lives in the Timber Lake subdivision east of Tallahassee. She was still at home Sunday evening but had no power and said if the rain continued, she would join neighbors who had already left by boat.

Fay made landfall a record four times in Florida before it was downgraded to a tropical depression late Saturday. The storm caused widespread flooding as it zigzagged across Florida for nearly a week.

Fay has been blamed for 13 deaths in the U.S., 11 in Florida and one each in Alabama and Georgia. A total of 23 died in Haiti and the Dominican Republic from flooding.

MIAMI -- A cab driver may have fallen asleep at the wheel early Sunday morning before plowing into a group of bicyclists out for a leisurely morning ride on the MacArthur Causeway, police said.

The 8 a.m. accident left many of the riders sprawled on the pavement in the eastbound lane and sent six to the hospital.

The most seriously injured was a 48-year-old man who was taken into surgery and listed in critical condition; the five others were in stable condition.

The other five suffered severe road burn when thrown to the pavement and were treated at the scene.

After the accident, two bicycles were still attached to the cab, one crushed underneath it, the other by its front passenger door. The cab's windshield was shattered.

Police identified the driver as Herbert Morais, 52, with the Checker Cab company.

"He's openly admitted to falling asleep behind the wheel of the car," said Detective Juan Sanchez, a Miami Beach police department spokesman. "At this point he hasn't been charged with anything. The investigation is still ongoing."

LEWISTON, Maine -- People worried about the high cost of keeping warm this winter will draw little comfort from the Farmers' Almanac, which predicts below-average temperatures for most of the U.S.

"Numb's the word," says the 192-year-old publication, which claims an accuracy rate of 80 to 85 percent for its forecasts that are prepared two years in advance.

The almanac's 2009 edition, which goes on sale Tuesday, says at least two-thirds of the country can expect colder-than-average temperatures this winter, with only the Far West and Southeast in line for near-normal readings. "This is going to be catastrophic for millions of people," said almanac editor Peter Geiger.

The almanac predicts above-normal snowfall for the Great Lakes and Midwest, especially during January and February, and above-normal precipitation for the Southwest in December and for the Southeast in January and February. The Northeast and Mid-Atlantic regions will likely have an unusually wet or snowy February, the almanac said.

SAN ANTONIO -- A San Antonio couple is accused of trying to trying to trade sex with the woman's 5-year-old daughter for an apartment, a used car and child care for her 10-month old daughter.

Jennifer Richards, 25, and her married boyfriend, Sean Michael Block, 40, appeared before U.S. Magistrate Judge Nancy Stein Nowak on Friday. Richards is charged with using interstate facilities to transmit information about a minor. Block is charged with distributing child pornography.

Nowak ordered Block held. Richards' detention hearing was delayed until Tuesday, the San Antonio Express-News reported Sunday.

According to an affidavit unsealed last Tuesday, the investigation began when an informant told the FBI about a text message allegedly sent by Block reading: "Nice piece 5 yrs old belongs to my gf and she wants to sell it."

Richards and Block crafted a deal that, in addition to the apartment and used car, included child care for Richards' 10-month-old daughter, whose sexual service the couple intended to sell later, Rex Miller, the FBI's lead agent on the case, testified.

The couple had also hoped to blackmail the informant, Miller said.
