The West Coast is bracing for Tropical Storm Hilary, and Arizona residents are bracing for the risk of dangerous flash flooding.
Hurricane Hilary weakened to a Category 1 as it approached Baja California in Mexico Sunday morning and downgraded further to a tropical storm before reaching southern California. But it still has potential to bring a historic amount of rain to the Southwest.
The western reaches of Arizona are the most at risk for flooding and high winds, and residents are preparing for the storm. The Mohave County Sheriff's Office has issued evacuation orders for parts of Lake Mead due to flooding risks.
"With high winds, we want to anchor everything down that we can. Put everything away. Furniture, anything that could become a flying object," said Tony Badilla, the Yuma County Emergency Management Director.
The county gave out thousands of sandbags Saturday and is asking everyone to stay inside once the storm hits.
Hurricane Hilary: Where Arizonans can get sandbags ahead of possible flooding in parts of the state
As Hurricane Hilary is raising concerns for flooding in Arizona, various county and city governments are making sand and sandbags available for residents who want to protect their homes from potential floodwaters.
The National Weather Service is warning parts of western and northern Arizona of the possibility of tornadoes. There's a 2-4% possibility that it could occur in areas including Kingman, Lake Havasu City and as far east as Flagstaff.
"The National Weather Service just issued a High Wind Advisory for us. We’ll have winds up to 65 mph. Obviously, we’re gonna have up to an inch and a quarter of rain," Badilla said. "So we’re expecting the worst and preparing for that, so we’ll see how this plays out [Sunday]. They did put a slight warning out for possible tornadoes along the Colorado River area, which is our area."
The Phoenix area could see widespread rain heading into Sunday evening and overnight Monday, but the brunt of the storm will be felt further west. The highest potential for flooding will start at 3 p.m. through midnight, according to the National Weather Service.
