information from public authorities
The Pirna district office publishes the current situation regarding the fire on the Saxon and partly on the Czech side on the website every day. You will find the information right on the start page on the right-hand side.
The satellite images of the European Emergency Management Service provide an overview of the areas affected by the forest fire, which is updated every few days. The link below leads directly to the page for the forest fires in Bohemian-Saxon Switzerland. There it is best to click on the "200 dpi" link next to "PDF" or "JPEG" in the lower table in the rows with satellite images under "Downloadable items".
The current sources of fire can be roughly identified using heat maps. Zoom Earth also shows this over time.
