Salt Lake City, Utah – Flash flooding remains a real threat across much of Utah through Thursday as deep monsoonal moisture fuels intense afternoon thunderstorms and heavy rainfall. Areas most at risk include southern Utah, slot canyons, normally dry washes, and regions near recent burn scars.
According to the National Weather Service in Salt Lake City, the greatest flood risk will peak during the afternoon and early evening hours, especially in southern Utah. Monsoon-driven storms are expected to deliver rapid bursts of rain, capable of overwhelming dry creek beds and triggering dangerous runoff. The flash flood threat also extends into parts of southwest Wyoming.
Officials urge hikers and outdoor recreationists to avoid flood-prone areas, including narrow canyons and unpaved backcountry roads. Even short-term downpours could become life-threatening in these regions. Burn scars from past wildfires can worsen flooding as the terrain is unable to absorb rainfall.
The NWS warns that the daily flood threat could vary depending on storm development, with risk potentially decreasing later in the day. However, residents and visitors should remain alert and ready to move to higher ground if storms approach.
Flash flood advisories remain in effect across the region through Thursday, with additional updates likely.
