Forecast Louisiana is the definitive portal for the Pelican State's weather and climate — built to make the official National Weather Service forecast fast, clean and highway-clear for all 64 parishes, from the Sabine to the Pearl and from the Arkansas line to the passes at the end of the river.
Louisiana is the only state whose map keeps changing. The Mississippi built the bottom third of it out of sediment and the levees that now hold the river in place have stopped resupplying it, so the coast is going back to open water at something like sixteen square miles a year — and every square mile lost is surge protection lost. That is the long story. The short ones are a hurricane season that runs June to November and has put three landfalling majors on this coast since 2020 — Laura, Zeta and Ida; a severe season with two peaks, spring and November, at the southern end of Dixie Alley; and rain in quantities the rest of the country does not deal with — Baton Rouge took two feet of it in 48 hours in August 2016 from a storm that never had a name. Forecast Louisiana is built around those.
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. Louisiana takes an oyster-shell paper and a blue-crab cyan accent, on Gulf haze — the color of the claws on Callinectes sapidus, which Louisiana has long landed more of than any other state.
Louisiana is covered close-up by 9 region sites, each on its own subdomain of forecastlouisiana.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 Louisiana, not separate sites: /about on any of them lands back here.
Louisiana touches three states and all three are live: Forecast Texas across the Sabine, Forecast Arkansas across the north line at the Delta and Toledo Bend, and Forecast Mississippi across the river and the Pearl — each tinted in its own accent on the hero map and clickable from it. The rest of the Forecast <State> network is part of the same system.
