Rainfall totals in every listed city
Where these numbers come from
- What Raindex measures
- Raindex measures observed rainfall from NOAA’s Multi-Radar Multi-Sensor system (MRMS) at roughly 1 km resolution, combining radar estimates with rain-gauge adjustment. The gauge-corrected pass runs about 97 minutes behind real time, so a recent total can be revised upward or downward as gauge data arrives.
- What neither one can tell you
- A 30-year average says nothing about this week. A radar estimate is still an estimate: it can disagree with the gauge in your yard because of terrain, the height of the radar beam over your property, how rainfall varies within a single kilometre, and the fact that a gauge itself under-catches in wind. Raindex labels each reading gauge-adjusted, radar only or provisional so you can see which you are looking at. It does not publish an accuracy percentage, because that is not a number this data can honestly support.
