Weather warnings and advisories

A hazardous weather outlook is in place for the western two thirds of Utah. A warm system will bring heavy rainfall to Southern Utah. Valley rain and mid-high mountain snow can be expected across northern Utah.

With the heavy rainfall across Southern Utah this weekend, area rivers will be running high. Slot canyons and small streams are expected to be running high and fast. Those with outdoor plans in these areas are urged to monitor forecasts over the next several days. Valley snow is expected with a colder storm Monday night into Wednesday morning. Significant snow accumulations are possible for much of the area.

Strong winds are expected in the mountains Saturday, while western valleys may see gusty winds.

In addition, there’s a flood watch in effect until Sunday afternoon for a portion of Southern Utah, including south central Utah, Southern Mountains, Utah’s Dixie and Zion National Park. Significant rises are expected on area waterways, particularly in smaller streams and drainages, with flooding possible. Smaller basins in steep terrain, dry washes, slot canyons and urban areas with poor drainage will be most susceptible to flooding. Life- threatening flooding is possible in slot canyons.

Travel may be impacted on back country roads that cross dry washes. Those planning to engage in outdoor activities should monitor the forecast and make contingency plans.

A winter storm warning is also in place until Sunday evening for the Southern Mountains and the cities of Loa, Panguitch and Bryce Canyon.

This winter storm would bring total snow accumulations of 1-2 feet.  Travel could be very difficult or impossible over mountain passes, including near Brian Head. Blowing and drifting snow will significantly reduce visibilities. Expect winter driving conditions with heavy, wet snow covered roads.
