Real-time and forecasted atmospheric conditions along the major north-south highway spanning the West Coast of the United States are essential information for travelers. This information typically includes temperature, precipitation, wind speed, visibility, and any hazardous conditions such as fog, ice, or snow. An example would be a prediction of heavy snow in the Cascade Mountains impacting travel over mountain passes.
Access to current and predicted road conditions facilitates safe and efficient travel. Being aware of potential delays or closures due to inclement weather allows drivers to make informed decisions, such as adjusting travel plans, choosing alternate routes, or delaying trips altogether. Historically, obtaining this information was challenging, relying on radio broadcasts or calling highway patrol offices. Now, digital platforms offer readily available and frequently updated data, contributing significantly to traveler safety and reducing weather-related incidents.
