A new executive order from President Donald Trump that's part of his effort to invigorate energy production raises the possibility that his Department of Justice will go to court against state climate change laws aimed at slashing planet-warming greenhouse gas pollution from fossil fuels.

Trump's order, signed Tuesday, comes as U.S. electricity demand ramps up to meet the growth of artificial intelligence and cloud computing applications, as well as federal efforts to expand high-tech manufacturing. It also coincides with "climate superfund" legislation gaining traction in various states.

Days of unrelenting heavy rain and storms that killed at least 18 people worsened flooding as some rivers rose to near-record levels and inundated towns across an already saturated U.S. South and parts of the Midwest.

Cities ordered evacuations and rescue crews in inflatable boats checked on residents in Kentucky and Tennessee, while utilities shut off power and gas in a region stretching from Texas to Ohio.

Parts of the Midwest and South faced the possibility of torrential rains and life-threatening flash floods Friday, while many communities were still reeling from tornadoes that destroyed whole neighborhoods and killed at least seven people.

Forecasters warned of catastrophic weather on the way, with round after round of heavy rains expected in the central U.S. through Saturday.

Indonesian rescuers recovered 10 bodies after a landslide struck vehicles on a hilly road on the country's main island of Java, police said Friday.

Torrential rains pushed mud, rocks and trees down the mountainside road on Thursday, burying a van with seven people aboard and a pickup truck with three traders and full of vegetables near Watu Lumpang, a resort area in East Java's Mojokerto district, said local police chief Andi Yudha Pranata.
