Forecast Utah is the definitive portal for the Beehive State's weather and climate — built to make the official National Weather Service forecast fast, clean, and highway-clear for all 29 counties, from the Arizona Strip and the Colorado River up the length of I-15 to the Idaho line.
Utah is the second-driest state in the country and it is also one of the snowiest, and those two facts are the same fact. Storms come in off the Pacific already wrung out by the Sierra and the Great Basin ranges, and then they hit the Wasatch — a wall that stands 7,000 feet above the valley floor in seven miles, with a salt lake at the base of it that never freezes. What is left of the moisture goes up that wall and comes down as some of the driest, deepest snow measured anywhere: Alta averages more than 500 inches while Salt Lake City, ten miles away and 5,000 feet lower, gets fifteen inches of water a year. The same geometry works against the valley in reverse — the cold pool that settles into it behind a winter high does not leave, and the inversion that follows is the state's most reliable hazard. South of the plateaus the state changes climate entirely, into a Mojave corner at St. George and a monsoon that fills the slot canyons of the Colorado Plateau in August. Forecast Utah is built around that vertical grain rather than the flat map of it.
The look borrows from the American Interstate system — the reflective paper, the green guide signs, the blue service signs, the brown recreation signs, and the red-white-and-blue route shields — set in Overpass, the typeface drawn from the Highway Gothic lettering on those signs. Utah takes a salt-and-sandstone paper and a Great Salt Lake rose accent — the color of the lake's north arm, cut off from its fresh water by the railroad causeway and turned rose by the halophiles that live in what is left — its own note in the network.
Utah is covered close-up by 3 region sites, each on its own subdomain of forecastutah.com — the same maps, the same live radar and the same climate record as this site, drawn to one metro or region instead of the whole state, with a page for every city in it. They are part of Forecast Utah, not separate sites: /about on any of them lands back here.
Utah has all six of its neighbors live: Forecast Nevada across the salt flats at Wendover, Forecast Idaho at Snowville and the Bear River, Forecast Wyoming over the line at Evanston and Flaming Gorge, Forecast Colorado on I-70 east of Green River, Forecast Arizona at the Virgin River Gorge and Lake Powell, and Forecast New Mexico at the single point of Four Corners — all tinted in their own accent on the hero map and clickable from it. The rest of the Forecast <State> network is part of the same system.
