Texas A&M AgriLife Extension has produced a series of short videos on prescribed burns called “Living with Texas Fire”. Even though it is focused on Texas, a lot of the information provided in the series is useful to anyone who is considering doing a prescribed burn. Of course, you will need to check your local regulations for proper permitting in your area. A couple of the video segments are on weather considerations.
