Tropical Storm Hanna struck an overhead slam at the U.S. Open, postponing one men's semifinal and forcing the women's final off its usual Saturday date for the first time in 34 years.

With whipping wind and rain moving up the Atlantic Seaboard, the title match between Serena Williams and Jelena Jankovic was shifted from Saturday night to Sunday night.

"I'll be ready for Sunday, Monday, Tuesday," Williams said. "Doesn't matter."

The men's final was rescheduled from Sunday afternoon to Monday afternoon. It's the first Monday final for the men at the Open since 1987, when Ivan Lendl defeated Mats Wilander.

Hanna cut short the Rafael Nadal-Andy Murray semifinal. That match resumes Sunday afternoon, with Murray up 6-2, 7-6 (5), 2-3.

Roger Federer, going for a fifth straight Open crown, beat the rain and Novak Djokovic with a four-set victory in his semifinal.

Hanna also took out two baseball games. The Phillies-Mets game in New York was washed out, with the top two teams in the NL East to play a day-night doubleheader Sunday.

In Baltimore, the opener of a day-night doubleheader between the Orioles and Oakland Athletics was postponed. That game originally was set for Sunday afternoon, but had been moved to Saturday because of a scheduling conflict with the Baltimore Ravens.

The NASCAR race at Richmond International Raceway, which will set the field of 12 drivers for the 2008 series championship, already had been switched from Saturday night to Sunday. The Nationwide Series race went from Friday night to Sunday night.

Hanna Knocks Out Power

Tropical Storm Hanna continued to move up the Atlantic coast Saturday. Forecasters said it moved into Virginia and New England, dumping torrential rain in many places.

Top winds were still near 50 mph.

The storm was expected to bring 4 to 6 inches of rain from central North Carolina through the eastern mid-Atlantic states and into southern New England. The rain has brought flash flooding in some areas.

WBAL-TV in Baltimore reported a person was killed and a child was injured in a weather-related crash on Interstate 95 as rain from Hanna caused hazardous driving conditions. Officials said the driver of a sport utility vehicle died after the vehicle veered off southbound I-95 near Powder Mill Road in Beltsville and hit a tree.

Authorities in Haiti fear that the death toll in the flooded city of Gonaives could rise into the hundreds. But they say they haven't found that many bodies, despite some media reports that more than 500 are dead. The Haitian government said Saturday afternoon that 163 people across Haiti are confirmed dead in the aftermath of Tropical Storm Hanna. Hurricane Ike is approaching the hemisphere's poorest country, bringing the likelihood of more rain.

By midday, almost 100,000 homes and businesses along the East Coast were without power.

In the resort town of Ocean City, Md., lifeguards were posted at all entrances to the beach to urge people to stay well back from the waves. But that didn't stop surfers from trying to ride the swells that reached 12 feet by late morning.

Peacekeepers, Aid Workers Race To Feed Haitians

Relief workers still haven't been able to reach thousands of people left stranded and hungry by Tropical Storm Hanna in Haiti. And now there's a threat of more rain from Hurricane Ike for the flooded city of Gonaives.

More than 160 people have been confirmed dead in Haiti. Officials said a report of a higher death toll was based on an unconfirmed estimate.

Flooded roads have stood in the way of efforts to get food to those who need it, even as Ike threatens to trigger more deadly flooding.

A container ship chartered by the World Food Program arrived Friday near Gonaives. It was guarded by Argentine peacekeepers with assault rifles. Within hours, the U.N. started distributing high-energy biscuits and water to emergency shelters. Operations were suspended at dark because it was considered too dangerous.

Josephine Dissipates Near East Atlantic

Josephine has weakened to a tropical depression.

At 5 a.m. Atlantic time, the center of Josephine was about 855 miles west of the Cape Verde Islands.

It was moving toward the west-northwest near 7 mph. Maximum sustained winds are near 30 mph. Little change in strength is forecast during the next 48 hours.
