The convective and fire weather outlook shapefiles and KML files are created based on the outlook/fire points product (as defined by KWNSPTS/KWNSPFW, respectively) then converted to GeoJSON in two versions: overlay and non-overlay. The KML and shapefile are then created based on GeoJSON using GDAL utilities. Additional reformatting steps were taken post-GDAL transformation to provide KML color-filled polygons, legends and KML tags to improve readability.

Starting on January 30, 2020. Day 2 convective outlooks contain individual probabalistic hazard (tornado, wind, hail) similar to Day 1 outlooks replacing total probablistic hazard.

Starting on October 16, 2019. Day 1 - 8 convective outlooks will include layered (wedding cake) and no-layered (donut holes) GeoJSON files. Details below.

Please note that the categorical outlook shapefiles contain DN attributes which are based on the NDFD grid values which are defined as:
2 - Thunderstorm

3 - Marginal Risk

4 - Slight Risk

5 - Enhanced Risk

6 - Moderate Risk

8 - High Risk

For probabilistic outlook shapefiles the DN value denotes the probability (i.e., DN = 2 denotes 2%).
