★ WEATHER RADAR: LEVEL 2, LEVEL III & TDWR
GPU-rendered radar, crisp at any zoom. NEXRAD Level 2 decoded on your device: Reflectivity, Velocity, Correlation Coefficient, Spectrum Width, and Storm-Relative Velocity, with elevation tilt selection. Plus Level III dual-pol (ZDR, CC, KDP, HCA), derived products (VIL, Digital Precip Rate, rotation), storm tracks, mesocyclone and TVS markers, VAD Wind Profile, and the 45-site TDWR network. Add a Mesoanalysis layer, Storm Cell Deep Dive, and dual-view compare. 16 .pal color tables, or import your own.

★ ANIMATED & COMPOSITE RADAR
Loop recent volumes (play, scrub, speed). Pair with a GPU-crisp CONUS MRMS mosaic from the full catalog, including the FLASH flash-flood suite, with 12-hour playback and tap-to-read values.

★ SEVERE WEATHER ALERTS
Background NWS warnings with a polygon preview map, even when the app is closed. Filter modes: Standard, Outbreak, and PDS/Emergency only. Watch zones: current location, home, any city, state, or nationwide. Severe alert tone, Do Not Disturb override, and an optional full-screen alarm for Tornado Emergency and PDS warnings (Android 14+, off by default). Each warning shows estimated population inside the polygon.
