20250507 09465600 1.0 TRUE Drought Hazard Drought Hazard Average Annual Weeks About this map: This depiction of drought hazard zones across Puerto Rico is based on outputs from the United States Drought Monitor (USDM). USDM data indicate drought conditions on a weekly basis (2000-2019). The hexagonal grids utilized here provide a standardized method for overlaying multiple hazards each with different spatial representations. An average annual number of drought weeks is calculated for each hexagonal grid, representing 0.5 sq. miles, and is symbolized using an equal interval classification scale showing areas of higher drought frequency across the Island. Spatial analytics derived by the vulnerability mapping and analysis platform at the university of Central Florida – www.vulnerabilitymap.org
