SALT LAKE CITY — Flood watch alerts are in place for St. George, Richfield and Manti through Monday, as Hurricane Hilary prepares to make landfall near the southwestern United States.
The National Weather Service expects showers and thunderstorms with a 15% to 35% chance of flash flooding in west-central and southwest Utah. It warned that slot canyons, dry washes and areas near burns scars have the highest risk of flooding.

According to Christine Kruse, a lead meteorologist with the NWS, Utah will be impacted by Hillary in a few ways.
“First up, we are seeing rain across western Utah this morning that associated with that increasing moisture,” she said. “Later today, we are expecting some strong to severe thunderstorms across south western Utah.”
Kruse said, with time, the storms are expected to spread across northern Utah, probably overnight.
“The other part of this is we’re expecting really strong winds,” she said. “Potentially gusts up to 60 mph.”
These winds are expected from roughly north of Cedar City and into Box Elder County.
The NWS cautions those planning on recreating outdoors to monitor the weather and encouraged those driving to not go across flooded backcountry roads.
Forecasts predict strong to severe thunderstorms making their way across southwestern Utah on Sunday. The NWS said the main threats are “strong damaging winds and a very low chance of tornado potential.”
