As remnants of Subtropical Storm Alberto spread into the Great Lakes region, people were keeping a weary watch on dams and hillsides Thursday as rains from the storms have triggered floods and mudslides in the Appalachians of the Southeast.

In the North Carolina mountains, one of those landslides was blamed for a gas leak that destroyed a home, killing two people. Boone police Sgt. Shane Robbins said the landslide resulted in the "catastrophic destruction" of the home Wednesday afternoon because of a gas leak.

Elsewhere, four dams being closely watched by a state team of special engineers were holding up, North Carolina Gov. Roy Cooper said Wednesday.

But Cooper went ahead and declared a state of emergency for his hard-hit mountain counties, saying the forecast for the rest of the week calls for isolated heavy rain storms that could instantly cause flooding in areas that have had 20 inches (50 centimeters) of rain in the past 15 days.

"This storm isn't yet over. I'm urging people to keep a close eye on forecasts," Cooper said.

Alberto, while still spinning like a classic tropical storm, has managed to make its way since a Memorial Day landfall in the Florida Panhandle to just outside of Chicago. Forecasters said it would still bring rain and gusty winds to the Great Lakes this week.

Alberto's heavy rains have been widespread. Scattered flooding was reported in several states from Alabama through Tennessee, Kentucky, Illinois, the Carolinas and Virginia and West Virginia.

In Hopkinsville, Kentucky, high winds and heavy rains gave Sherry Key a fitful night's sleep.

"I have dogs and they're terribly afraid of storms, so they were on top on top me all night," said Key, an airport office manager.

The worst of the flooding was in the Appalachian Mountains. Up to 7 inches (18 centimeters) of rain caused flooding in Helen, a mountain town in Georgia, the National Weather Service said.

Atlanta station WAGA-TV reported that several roads near the downtown area of that German-styled tourist destination were shut down because of the rising water. No injuries were reported.

Two deaths had been reported during the storm's passage. A television news anchor and a photojournalist were killed Monday in North Carolina while covering the weather, when a tree became uprooted from rain-soaked ground and toppled onto their SUV, authorities said. WYFF-TV of Greenville, South Carolina, said news anchor Mike McCormick and photojournalist Aaron Smeltzer died.

In the mountains of North Carolina, two Department of Transportation workers survived a close call when their dump truck was swept away by a mudslide in McDowell County while trying to clean debris from an earlier slide. The men were able to climb from the overturned truck and stand on its side in the Catawba River until they were rescued, Gov. Cooper said.

Authorities in Cuba say Alberto left four people dead there as the storm drenched the island in heavy rain. Interior Minister Julio Cesar Gandarilla said late Tuesday they died as a result of "recklessness" during the storm. He gave no details. The deaths occurred as authorities worked to contain an oil spill in central Cuba's Cienfuegos Bay that followed the flooding of nearby oil refinery.
