GPU Radar: Level 2, III & TDWR
GPU-rendered and crisp at any zoom. NEXRAD Level 2 decoded on-device (reflectivity, velocity, correlation coefficient, spectrum width), plus WSR-88D Level III, dual-pol products (ZDR, CC, KDP, hydrometeor classification), derived products (VIL, Digital Precip Rate, storm-relative velocity, rotation), vertical cross sections, a VAD Wind Profile panel, storm tracks with mesocyclone and TVS markers, and the 45-site TDWR network.
Learn moreComposite & Animated Radar
CONUS MRMS composite mosaic, now GPU-rendered and crisp at every zoom, with a full transport bar (play, scrub, speed), up to 12-hour playback, and a quality-controlled base-reflectivity mosaic.

A beautiful animated wind layer streams live surface wind across the map as flowing, speed-colored particles. See exactly where the wind is ripping at a glance.
Learn moreDual-View Radar Compare
Split the screen to compare two radar views side by side (different products or two sites), each with its own controls.
Learn moreOn-Device Soundings
Tap anywhere on the map for a full atmospheric profile: skew-T, hodograph, and complete sounding analysis from observed balloon data and HRRR forecasts, with a forecast-hour scrubber.
Learn moreMesoanalysis
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.

Tens of thousands of DOT traffic cameras across 37 states, plus FAA, Windy, NOAA buoy, USGS volcano, National Park, and ALERTWildfire cameras, with live video where it's offered.
Learn morePresence (opt-in)
Turn it on to see other Spotter Tools Pro users on the map (avatars, usernames, and bios) and let them see you. Off by default; nothing is shared unless you opt in.
Learn moreSmart Push Alerts
Background watcher fires NWS warning notifications whether the app is open or closed, with watch zones, filter modes, custom sounds, full-screen tornado-emergency takeover, and an estimated population count inside each warning polygon.
Learn moreNWS, SPC & Convective Outlooks
Warnings, watches, mesoscale discussions, and a full outlooks suite: SPC convective Day 1 to 8, thunderstorm, excessive rainfall, fire weather, winter storm severity, CPC 6 to 10 day, and drought, all overlaid on the map.
Learn moreCritical Alerts on iOS
Apple approved Critical Alerts for Spotter Tools Pro. Tornado Emergencies, Particularly Dangerous Situation warnings, and Flash Flood Emergencies can break through Do Not Disturb and the silent switch when you opt in.
Learn moreAir Quality (AQI)
EPA AirNow air quality on the map: Combined AQI, PM2.5, and Ozone, with a 24-hour loop animation and a smooth contour surface. Tap any station for its reading.
Learn moreSurface Fronts & Pressure
WPC surface analysis on the map: cold, warm, stationary, and occluded fronts plus high and low pressure centers, from the Coded Surface Bulletin.
Learn moreWeather Models
Overlay HRRR, GFS, and RRFS forecast guidance (reflectivity, temperature, wind, CAPE, and precipitation) with an animated time bar and color legend.
Learn moreStorm Track Projection
Drag a heading line to draw a forecast cone with configurable speed and spread, then auto-detect every town inside it with an ETA.
Learn moreLong-Press Map Menu
Press and hold anywhere on the map for a quick context menu: pull a point sounding, list the nearest radars, inspect that spot, or find the nearest cameras.
Learn moreGPS Beacon to Spotter Network
Foreground and background beacon transmission so the NWS and fellow spotters see exactly where you are. Auto-restarts on device boot.
Learn moreSevere Weather Reporting
Submit tornado, hail, wind, flood, funnel, wall-cloud, and damage reports straight to Spotter Network, with the exact fields the form expects and offline queueing.
Learn moreCustomizable Color Tables
Sixteen built-in palettes plus import your own GR2Analyst-style .pal files for BR, BV, and CC.
Learn moreSurface Observations & METARs
Live METAR station data plus RTMA analyzed surface fields (temperature, dew point, theta-e, wind, and gusts) and MRMS observed precipitation totals, all as true observations rather than forecast output.
Learn moreStorm Cell Deep Dive
Tap a cell for an expanded readout: rainfall rate, peak reflectivity, storm-top height, footprint, mass and volume, an age tracker, and at-a-glance severe indices.

See It in the App
Every one of these was recorded right in the app. Here's what the headline features actually look like in the field.
Storm structure
Radar Cross Sections
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.
3D radar
Tilt the Map, See the Beam Rise
Pitch the map and the radar beam climbs with distance, the way the real beam does. Watch how a storm stacks up in the sky instead of guessing from a flat picture.
Live wind
Watch the Wind Move
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.
Severe parameters
Mesoanalysis
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.
Cell interrogation
Storm Cell Deep Dive
Tap a cell for an expanded readout: rainfall rate, peak reflectivity, storm-top height, footprint, mass and volume, an age tracker, and at-a-glance severe indices.
Storm tracking
Storm Tracks & Cell Characteristics
Level III storm tracks and cell attributes show where each cell is headed and how it's evolving, so you can size up the strongest storms at a glance.
Compare
Dual-View Radar
Split the screen to compare two radar views side by side (different products or two sites), each pane with its own independent controls.
On the ground
Live Traffic & Sky Cameras
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.

Built by a Spotter, for Everyone Who Watches the Sky
Spotter Tools Pro started as a focused field tool for certified SKYWARN storm spotters and Spotter Network members, and it still is. But the same pro-grade radar, alerts, and live cameras now serve storm chasers and weather enthusiasts too. No bloated features, no ads, no data harvesting. Just the tools to keep you informed during severe weather.
Your position data goes directly to Spotter Network. Weather data comes directly from the NWS and Storm Prediction Center. No ad networks, no tracking, and no middlemen in that path. The only thing we store is an optional account, if you choose to create one.
