At least 22 people were killed and rescue crews searched desperately Sunday amid shattered homes and tangled debris for dozens of people still missing after record-breaking rain sent floodwaters surging through Middle Tennessee.

Saturday's flooding in rural areas took out roads, cellphone towers and telephone lines, leaving families uncertain about whether their loved ones survived the unprecedented deluge. Emergency workers were searching door to door, said Kristi Brown, a coordinator for health and safety supervisor with Humphreys County Schools.

A wildfire burning for a week in Northern California continued to grow out of control, one of about a dozen big blazes in the drought-stricken state that have destroyed hundreds of homes and forced thousands of people to evacuate.

There was zero containment Sunday of the Caldor Fire, which had charred nearly 154 square miles (399 square kilometers) of trees and brush in the northern Sierra Nevada after breaking out Aug. 14. The cause was under investigation.

Henri was downgraded to a tropical depression as it churned deeper inland early Monday, with experts predicting it will settle for awhile near the New York-Connecticut border before heading back east. Here's everything to know about the Northeast weather that's tropical in name, but far from its titular home:

IS HENRI STILL A HURRICANE?

Romania will soon conduct a census of its protected brown bears using DNA for the first time, with tensions raised between villagers fearing further attacks and conservationists warning against looser hunting laws.

Incidents with hungry bears descending into villages have sparked the ire of residents, in a country that has seen around 100 attacks over the last three years. 

Hurricane Grace — temporarily knocked back to tropical storm force — headed Friday for a second landfall in Mexico, this time taking aim at the mainland's Gulf coast after crashing through the country's main tourist strip.

The storm lost punch as it zipped across the Yucatan Peninsula, but it emerged late Thursday over the relatively warm Gulf of Mexico and was gaining energy.

Authorities combing areas of North Carolina flooded by the remnants of Tropical Storm Fred said Thursday that two people have been found dead and about 20 were unaccounted for.

Meanwhile, Fred — now a post-tropical cyclone — was pushing through New York and New England with drenching rains, and Tropical Storm Henri was sending dangerous waves onto East Coast beaches. Forecasters said Henri will likely strengthen into a hurricane as it approaches the northeastern U.S. early next week.

July was the planet's hottest month in 142 years of record keeping, according to U.S. weather officials. Several U.S. states — including California, Nevada, Oregon and Washington — also saw their hottest ever July.

In August, wildfires continued to rage across the western United States and Canada, southern Europe, northern Africa, Russia, Israel and elsewhere.

A major wildfire burning northwest of the Greek capital decimated large tracts of pine forest for a third day as hundreds of firefighters, assisted by water-dropping planes and helicopters, battled the flames Wednesday.

The blaze in the Vilia area broke out Monday shortly after another wildfire started to the southwest of Athens. Several villages and a nearby nursing home received evacuation orders.

A wildfire raged through a small Northern California forest town Tuesday, burning dozens of homes as dangerously dry and windy weather also continued to fuel other massive blazes and prompted the nation's largest utility to begin shutting off power to 51,000 customers.

The Caldor fire in the northern Sierra Nevada had burned an estimated 50 homes in and around Grizzly Flats, a town of about 1,200 people, fire officials said at a community meeting.

During last week's heatwaves in Italy and Spain, meteorologists in both countries announced provisional data suggesting temperature records had been set there.

But such claims need to be verified by the United Nations before being confirmed or rejected -- a process that can take months of careful scientific checking.
