Not how deep the rain was — how much of it fell, by volume. Using the
URMA 2.5 km precipitation analysis, we add up every drop over the last 30 days and multiply by the land it
covered to get gallons — for the whole Lower 48, and for every state, climate division, county, and Census urban area. Pick a
trailing window and a level of detail; tap a state to drill in.
