Tornado ID · Experimental
Tornado ID looks at every circulation the radar sees and estimates the chance a tornado is on the ground right now. Markers turn amber from 5%, orange from 30% and red from 60%, and a tap opens a plain-words card with the score, whether it is rising, how long the circulation has been tracked, how strong the rotation is, any debris signature and how high the beam is. Behind it is a machine learning model trained on every confirmed tornado from 2017 to 2025: more than 14,000 tornado track segments, 3,600 warnings that never produced one, and about 81,000 archived radar scans. It works on live radar and in archive mode. It is an estimate, not a warning, so always follow the National Weather Service.
How Tornado ID was built
Expert mode
One radar can be overshooting a storm while the radar beside it sees thousands of feet lower. Expert mode builds one image from up to three radars, each painting only the ground it is closest to, lined up to the same moment, with numbered badges so you always know which is which.
How it works
Precip Type
Colour the radar by what is actually falling: rain, snow, sleet or freezing rain. The strength comes from the radar and the type from the HRRR model, refreshed every 15 minutes, on single site radar and across the whole national mosaic.

Every one of these was recorded right in the app. Here's what the headline features actually look like in the field.
Storms in 3D
Radar has always been a flat slice. Now the whole Level 2 scan stands up as a solid you can orbit, so you see how a storm is built instead of inferring it one tilt at a time. Debris and rotation are marked inside the storm rather than hidden in a couplet you have to go find. Opacity follows rain rate, so heavy cores stay solid while light rain goes sheer and you can see straight into it from any side. Height is yours to set, including true scale, and the volume runs with the loop.
Nationwide in 3D
The 3D volume is not tied to one radar's umbrella. Switch to the national mosaic and you get the same solid anywhere in the lower 48, refreshed at about a two minute cadence, so a line running three states over reads as a structure rather than a smear. Site 3D and national 3D each carry their own opacity, so you can leave the mosaic sheer for context and keep your own radar solid on top of it.
Instant Level 2
Six Level 2 products paint in about a second: reflectivity, velocity, correlation coefficient, spectrum width, storm relative velocity and normalized rotation. The newest scan reaches the app about 12 seconds after the radar sends it, the scan time and VCP are printed right there, and if the fast lane is ever slow the app falls back to the full decode rather than leaving you waiting.
Hurricane Hunters
The Aviation layer puts live NOAA and Air Force reconnaissance on the map: the flight track, flight-level observations, and the vortex centre fixes radioed back from the eye. Open Recon Graphs for the whole mission charted, then export it as a clean two page picture brief, ready to post, or as spreadsheets in the aircraft's own units.
Point forecast
Long-press the map, or search a city, for the complete National Weather Service forecast at that exact spot. Current conditions, the day and night periods in the forecaster's own words, a 48 hour trend chart, the Area Forecast Discussion, and every detail the local office publishes for that cell. It keeps the last forecast so you can still read it without signal.
Storm structure
Draw a line across a storm and get a vertical slice through it, so you can read the structure from the ground up instead of only the view from above. Full-volume decoding means every tilt of the scan is there.
Severe parameters
SPC-style severe-weather parameters layered right under the radar: CAPE, shear, storm-relative helicity, and derived composites like Supercell and Significant Tornado, sampled anywhere with a bilinear crosshair readout.
Live wind
The live wind layer renders real surface wind as thousands of flowing, speed-colored particles, an at-a-glance read on outflow, convergence, and where it's really blowing. It draws on top of every layer, so it is never buried under the radar.
Compare
Split the screen to compare two radar views side by side (different products or two sites), each pane with its own independent controls. On Windows you can drag the divider to give either pane more room.
On the ground
Tens of thousands of cameras right on the map, with live video where the agency streams it, so you can see conditions on the ground in real time. A filter switches between everything, live video only, or stills only, with a count of each.

Capabilities
The highlights. Pro-grade tools with no ads, no third-party trackers, and no required account.
A machine learning model trained on nine years of confirmed tornadoes scores every circulation the radar sees, with amber, orange and red markers and a plain-words card for each one. Live, and in archive mode.
Learn moreStand the whole scan up as a solid you can fly around. Your own site's Level 2 volume in full detail, or the nationwide mosaic anywhere in the lower 48. Debris and rotation are marked inside the storm, cores show through the envelope, and it plays with the loop. Our servers build the volume, so it appears almost immediately.
Learn moreGPU-rendered and crisp at any zoom. Level 2 decoded on-device, Level III and dual-pol, the 45-site TDWR network, cross sections and storm tracks. Expert mode blends up to three radars into one image, and Precip Type colours rain, snow, sleet and ice.
Learn morePick a date and a time and the radar loads as it was at that instant, with storm tracks and mesocyclones along for the ride. Level 2 reaches back to 1991 and Level III to 1992, so Moore, El Reno and Bridge Creek all load.
Learn moreDraw the storm's leading edge and you are done. The motion comes off the radar automatically, and you get the swath, time marks across it, and every town in the path with its arrival time, down to villages of a few hundred people.
Learn moreA background watch worker with custom zones, including your home, population inside the polygon, filter modes up to Outbreak, custom sounds with DND override, and a full-screen takeover for Tornado Emergencies. Earthquake, wildfire and air quality alerts too.
Learn moreSign in once and your map, layers, radar setup, palettes, alert zones and home location follow you between phone, tablet and PC. Choose which groups sync, and delete the saved copy whenever you like.
Learn moreRecord what is on screen and hand it straight to the share sheet: single-site radar, the national composite, satellite, weather models or air quality. Every frame carries a stamp so the loop still says what it is once it leaves the app.
Learn moreSkew-T and hodograph for any point, observed balloon data or forecast profiles, with a full parameter analysis and a plain-language read of what the environment supports.
Learn moreForeground and background beacon transmission so the NWS and fellow spotters see exactly where you are, file reports with the exact fields Spotter Network expects, and come back on automatically after a reboot.
Learn moreTens of thousands of cameras on the map with live video where the agency streams it, across 61 state DOT and specialty sources covering 48 states. Filter to live video or stills and see conditions on the ground before you commit to a route.
Learn moreWorldwide tropical cyclone tracking with forecast cones, wind fields and every model's latest track. Plus live NOAA and Air Force reconnaissance on the map, Recon Graphs for the whole mission, and a flight export that turns it into a ready-to-post picture brief or spreadsheet.
