An increased risk of flash flooding exists again today across much of Utah as deep monsoonal moisture remains in place. If plans take you outdoors today, especially in slot canyons, normally dry washes, or areas near recent burn scars, stay tuned to the forecast and be ready to seek higher ground if storms threaten.
There is an increased risk of flash flooding for southern Utah national parks and recreation areas. Make sure to check in with local visitor centers or ranger stations before heading out and have a plan if threatening weather approaches.
