Interstate 40 traverses a diverse range of climates, from the arid deserts of California and Arizona to the humid southeastern states. Conditions can shift dramatically along its length, including extreme temperatures, heavy precipitation, high winds, and icy roads. For example, drivers might encounter scorching heat in the Mojave Desert and blizzard conditions in the mountains of New Mexico within the same cross-country trip.
Access to reliable and up-to-date information about atmospheric conditions along this major east-west artery is essential for safe and efficient travel. Being aware of potential hazards allows drivers to plan routes, adjust schedules, and take necessary precautions. This information is particularly crucial for commercial trucking, emergency services, and those traveling long distances. Historically, travelers relied on radio broadcasts and roadside signs for updates, but modern technology now provides real-time data through various apps and websites.
