Two children from El Paso are among three people who died in raging flash floods that struck the mountain forest resort town of Ruidoso, New Mexico, the town's mayor said.

More than 300 flooding reports have occurred across the U.S. since last Friday, with more heavy rain expected from Texas to the Mid-Atlantic.

A "considerable" flash flood warning has been issued in Boston as heavy, life-threatening rain pounds the city and areas to the south. Two to 4 inches of rain has fallen so far. Rainfall rates are reaching up to 2 inches per hour.
