Warming temperatures and melting mountain snow packs prompted the National Weather Service to put the western two-thirds of Utah under a Hazardous Weather Outlook advisory for the remainder of the week.
The advisory, which began Tuesday morning, came after Salt Lake City set a record high temperature on Monday of 93 degrees and the mercury soared near triple digits in the southern parts of the state. Forecasters warned that the heat was triggering higher flows of cold, swift water in the region’s rivers and streams.
"While flooding is not anticipated, these waterways will become very dangerous," the NWS stated, specifically warning parents to carefully monitor their children and pets on family outings near "any river or stream fed by spring snow melt runoff."
The Wednesday forecast for the Wasatch Front called for partly cloudy skies, high temperatures in the mid-80s, down a few degrees from Tuesday, and a slight chance for Wednesday afternoon thunderstorms.
Southern Utahns looked for sunny skies and highs in the low-90s on Wednesday, also a few degrees cooler than temperatures forecast for Tuesday.
The Utah Division of Air Quality awarded the entire state a "Green," or healthy air grade, but the Intermountain Allergy & Asthma pollen index noted that levels for mulberry, sycamore, maple and box elder were "very high" at the mid-week.
Salt Lake City’s Wednesday high temperature was pegged at 85 degrees, down from Tuesday’s 87-degree forecast; Ogden looked for 81 and 83 degrees, respectively; Provo 85 and 88; Logan 79 and 81; Wendover 84 and 85; Duchesne 83 and 85; Cedar City 82 and 87; St. George 92 and 98; and Moab 90 and 91 degrees.
