The National Fire Danger Rating System (NFDRS) uses weather, fuels, and fire occurrence data to calculate fire danger for a given area. Widely used across the United States, the NFDRS was recently updated to improve estimates of fuel moisture and simplify fuel model inputs.
The Status of Spring from the USA National Phenology Network tracks the progression of spring onset across the country using predictive models like the First Leaf and First Bloom Indices, which are based on recent temperature conditions. These indices show where and when the first signs of spring, such as the initial appearance of leaves and flowers, have arrived compared to a long-term average.
Fire Enviroment Mapping System (FEMS) is the official system for applying the National Fire Danger Rating System (NFDRS), providing access to fire environment datasets and online analysis tools in support of wildland fire preparedness and operational decision-making. Development and enhancement of the FEMS application continues.
