Switch hazards to redraw the map. Colors use one national scale (darker is higher), so you can compare this area to the rest of the country. Risk tiers are based on high-emissions projections that don't change with the scenario selector below.
Each county is shaded on a 1–10 dryness scale based on historical climate. Warmer colors = the visually drier end of the map: less moisture to start with.
