CDC reports West Nile cases up on Gulf Coast

ATLANTA -- West Nile virus cases in the United States rose this year, with a marked increase along the Gulf Coast, the government reported Thursday. Health officials had worried that standing water left by Hurricanes Katrina and Rita would allow mosquito populations to grow and the virus to proliferate. The number of human cases in Louisiana, Mississippi, Alabama and Texas increased by about 24 percent from 2004, the Centers for Disease Control and Prevention said.

ANCHORAGE, Alaska -- Three environmental groups sued the federal government Thursday, seeking to protect polar bears from extinction because of disappearing Arctic sea ice.

Icy weather causes power outages in southern U.S.

COLUMBIA, S.C. -- Freezing rain and ice across the South early Thursday closed schools, snarled traffic and caused power outages to more than 350,000 customers. The outages were caused by ice that formed on tree limbs and fell onto power lines. About 160,000 were without power in South Carolina, 102,000 in Georgia and 40,000 in North Carolina.

"The trees and power lines are down everywhere on the road. It's just dangerous to be out," said Rebecca Neal, who was using blankets to keep warm in her powerless Greenville home and thinking about finding a hotel for the night. The National Weather Service said the freezing rain was expected to continue in the region through Thursday evening and overnight temperatures were forecast to dip into the 20s. More power lines and tree limbs could snap under ice layers expected to grow to up to three-quarters of an inch thick.
