Thunderstorm.ws is a weather information website that helps people explore precipitation, storm movement and satellite imagery through interactive maps for countries around the world. Visitors can select a country, view available rain and storm radar, compare map layers, and save frequently used radar views in their browser without creating an account. The site explains how to interpret precipitation maps, check timestamps and colour scales, and understand that radar is not lightning detection. It also directs users to official weather warnings and emphasizes seeking shelter when thunder is heard.

Additional tools include location-based seven-day forecasts, with outlooks for selected cities and information such as humidity, dew point, cloud cover and pressure when available. The site explains forecast symbols, limitations and uncertainty, and cautions that missing thunder indicators do not mean conditions are safe. Educational resources cover storm safety, warning levels and typical thunderstorm seasons, including regional patterns in the United States. Thunderstorm.ws presents its maps and guidance as aids to understanding weather, not substitutes for official alerts or local safety decisions.
