Due to Stan's position within a large area of convective activity and thunderstorms, the hurricane's effects were far-reaching and widespread across Central America. Flash floods generated by the hurricane caused severe crop losses, particularly to coffee crops. Overall, Stan caused at least 1,668 deaths across six countries, with many others unaccounted for. Most of these fatalities occurred in Guatemala, and were mostly caused by mudslides triggered by torrential rainfall. The floods in Guatemala destroyed entire towns and disrupted exportation of petroleum. In Mexico, the heavy rains triggered additional mudslides and caused rivers to overflow, flooding nearby villages. Despite being relatively far from Stan as opposed to other countries, El Salvador was also severely affected by the hurricane. The Santa Ana Volcano erupted while Stan was producing heavy rains in the country, which contributed to the damage already wrought by mudslides. Transportation in the country was disrupted. Across the region, Stan caused $3.9 billion in damages, primarily due to torrential rainfall.
