Precip – Rain Totals & Weather

Precip runs its own nowcast for the hour ahead and updates it every five minutes, so you see when rain starts, how it changes, and when it clears. The company benchmarks that forecast against NOAA radar and rain gauges and publishes the scoring method on its site. That transparency is unusual, and it lets you judge the claim instead of trusting a badge.

The forecast follows a pin, not a city boundary. You can drop it on a back yard, a parcel, a job site, or a stretch of trail, and the app reports the nowcast, live precipitation, and measured history for that coordinate. Saved pins become a list you can sort by rainfall, last rain, soil moisture, or temperature.

After the storm, Precip shows what actually fell at your pin, drawing on radar and quality-controlled gauge reports. The record goes back to 2019, and yesterday's number gets refined as more gauges report in. The practical effect is a virtual rain gauge at every site, including places where nobody would ever install hardware. Snowfall totals and snow depth are included, which a tipping-bucket gauge can't measure at all.

A comparison view stacks the major global models, NOAA, ECMWF, DWD, and CMC, against the Precip blend for the same location. You can see where the models disagree before you commit a crew or a road trip, then come back later and check which one called it. It's the closest thing to holding a forecast accountable.

Alerts fire on your rules rather than on a generic severe weather feed. Set a precipitation, wind, or temperature threshold and the app checks it against measured conditions and the forecast for every site you watch. For a farm or a roofing company, that replaces a morning of calling around to ask how much each place got.

On the professional side, sites are grouped by region, crew, customer, or crop, with admin, editor, and viewer roles so the field can look without changing anything. Boundaries come in as shapefiles, KML, or an ESRI Feature Service, and area totals include the average, lightest, and heaviest rain across the shape. Records export at five-minute, hourly, daily, weekly, or monthly resolution, with up to five years in a single request.

Precip exposes a precipitation API at api.precip.ai. Pass a latitude and longitude, get back measured history and hyperlocal conditions: rainfall, snowfall and snow depth, temperature, humidity, wind, cloud cover, solar radiation, soil moisture, and soil temperature. There's also an embeddable map and chart UI if you'd rather not build the front end yourself.
