Two issues:
- On the legend, the scale switches from "in" on the left to "3ft" (3 feet?) on the right. This is inaccurate because the color scale seems to top out at 3 inches. This is also an issue for metric units, as it says "mm" on the left and "1m" on the right.
- Secondly, the color scale is inadequate for heavy rains. The pink sections cover a huge range of rain totals, with everything from about 8 to 20 inches (about 200 to 450mm) looking fully saturated pink. The scale should be more spread out!
