The National Weather Service has put the western two-thirds of Utah under a Hazardous Weather Outlook advisory extending over the next week.

The advisory, which took effect on Tuesday, warns that the spring snow melt and recent rainfall has swollen the region's rivers and streams. Flows are both bone-chilling and swift, and while flooding is not anticipated, the state's waterways are "very dangerous," forecasters say.

NWS officials caution parents to closely monitor the activities of children during any family outings near rivers and streams, noting that it only takes seconds for a youngster to be swept away and drowned.

The advisory extends into early next week, since scattered showers and isolated thunderstorms were expected to continue at least into the mid-week for much of Utah.

Northern Utahns looked for sunny skies Wednesday morning with building cloud cover and gusty winds heading into the evening. High temperatures were to reach into the mid-70s, a couple degrees cooler than Tuesday's forecast high.

Southern Utah, meanwhile, looked for the mercury to climb into the upper-80s Wednesday, mirroring Tuesday's forecast. Winds of 10-30 mph were expected under mostly cloudy skies.

The Utah Division of Air Quality rated the entire state's breathability as being in the "Green," or healthy range, while the Intermountain Allergy & Asthma had good news for allergy sufferers: only mulberry rated "high" on the organization's pollen index as of Tuesday.

Salt Lake City looked for a high temperature Wednesday of 75, down from 79 degrees forecast for Tuesday; Ogden expected 72 and 75 degrees, respectively; Provo 81 and 78 degrees; Logan 70 and 74; Wendover 72 and 79; Duchesne 78 and 73; Cedar City 78 and 79; St. George 91 and 90; and Moab 89 and 79 degrees.
