Resolution: approximately 1 km (0.6 mile)
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
