Spotter Tools Pro: Storm Radar

NEW: EARTHQUAKES LAYER Worldwide USGS coverage. Magnitude printed inside every dot, a pickable magnitude floor and time window, and a tap card with depth, timing, distance from you, felt reports, PAGER level, tsunami zone and review status. Optional felt-range overlays — a dashed ring is our estimate, a solid contour is the real measured ShakeMap. NEW: WILDFIRES LAYER Active NIFC incidents with optional burn perimeters and NASA FIRMS satellite hotspots. Tap a fire for acreage, containment, cause, behavior, crew size, complexity, managing team, fuel and cost to date, plus satellite activity: detections in the last 24 and 6 hours, peak radiative power and latest pass. Hotspot dots are tappable and sized by fire radiative power. AIR QUALITY, REBUILT • NOAA HMS smoke plumes, shaded under the AQI surface and radar • PM10 added to the pollutant picker, for dust and haboobs • AQI numbers on every visible dot at every zoom • An EPA category legend • A past-24-hours sparkline in the monitor sheet • Multi-day forecasts for the nearest AirNow reporting area, with Action Day badges • Dots paint instantly instead of taking 5-20 seconds NEW ALERT TYPES Earthquake, wildfire and air quality alerts join AlertWatch, each with its own settings and sound. All off by default. • Earthquakes alert on what you would actually feel rather than a fixed radius, with your own magnitude floor and an optional major-quakes-anywhere-in-the-US toggle • Wildfires alert on newly discovered fires near you and on rapid growth • Air quality alerts when the nearest monitor crosses the EPA category you choose Alert distances are now shown in miles everywhere. THREE NEW MAP STYLES Spotter Tools Grey, Midnight and Blue Nav. SHARPER LEVEL II VELOCITY Satellite-overlay noise is censored before unfolding instead of being mistaken for wind, and dense near-Nyquist wrap now folds properly. Velocity animations are re-solved frame by frame against the previous frame and the site's sounding, so loops no longer look worse than the live view. MESOSCALE DISCUSSIONS BY WATCH PROBABILITY Colored from grey-blue through blue, amber and orange to red at 80% and above, with the tier named in the info sheet. CAMERAS Camera feeds now update without an app release, and 92 dead streams found in an audit of all 368 curated cameras were repointed or retired. FIXES • Alert checks now run during background app refresh, so a closed app has a chance to notify you at whatever cadence iOS grants • Much lower memory and battery use when iOS wakes the app in the background • Radar imagery sat half a gate further out than every sampler thought, so the crosshair could read the neighboring value • Wind flow no longer hides under satellite imagery • Send yourself a test alert from notification settings, using your own sound profile and DND setting Now requires iOS 15.
