Weather officials say there’s a “pretty good chance” for moderate to possibly heavy rain to fall on the Santa Clarita Valley Sunday night through Monday morning, prompting a flash flood watch for areas affected by recent wildfires. “A watch is just to give people an early heads up that flash flooding is possible,” said meteorologist Scott Sukup of the National Weather Service. “Once we can actually see a storm on radar, if it looks like there’s going to be flash flooding we’ll issue a warning,” he continued. Of special concern is the Sand and Sage Fire burn areas where there could be mud and debris flow. The flash flood watch is in effect from 4 p.m. Sunday afternoon until 4 a.m. Monday morning.
