NOAA MRMS radar-only quantitative precipitation estimates for the grid cell containing the configured Cary coordinates. These are estimates, not measurements from a gauge at the property. Accumulation products can have slightly different valid times.

Hourly local rainfall

NOAA MRMS rolling one-hour radar estimates at the configured coordinates.
The Pi stores each newly published hourly estimate. Currently showing 3/24 collected hours; missing hours are marked with a dash while the local archive fills. Each bar represents rainfall estimated during the hour ending at its label.

Historical measured rainfall

Source: CARY 0.5 NW (NCWK0106), 0.5 miles from the configured coordinates. Latest report: 2026-06-18.
These charts use daily CoCoRaHS gauge measurements. An asterisk and striped bar indicate an incomplete period; its total may be understated.

Daily rainfall — past two weeks

Weekly rainfall — past sixteen weeks

Each bar is a seven-day period labeled by its ending date.

Monthly rainfall — past twenty-four completed months
