To a large degree, weather determines fire danger. During prolonged drought, tender plants that can be fuel for wildfires die and dry out. Cold weather, particularly during drought, speeds the dying and drying process. When the woods are dry, thundershowers bring only limited relief. The fuels dry again quickly and fires can occur even the next day.
Wind also dries fuels, and it causes fires to spread.
Do not burn on windy days. Locate flowers, hedges, etc. away from the house. Elimination of these same hazards around out-buildings such as barns, greenhouses and sheds, and from around animal cages, pens and corrals, will make them much safer from woods fires too. A grounds-keeping practice that all homeowners should routinely employ includes, keeping lawns trimmed and leaves raked, making sure housetop and rain gutters are free of debris such as dead limbs and leaves, and stacking firewood away from the house. Also, screen or other barriers should be used to prevent debris from blowing under the house or into the attic.
