The United States is preparing for the peak of fall foliage, with meteorological predictions indicating vibrant autumn colors across various regions. The changing leaves are driven by cooler temperatures and shorter daylight hours, causing chlorophyll breakdown and revealing underlying pigments. This natural event is expected to draw tourists and locals eager to experience the stunning landscapes. The timing of peak foliage differs by region, with northern areas typically changing earlier than southern ones. This year, the foliage is predicted to be particularly vivid due to favorable growing season weather conditions.
