Radar mode
A clear map for the weather right now
One map and one timeline are the default. The menu groups Views, Layers, and Your Map, with radar products, storm attributes, forecasts, and saved places close at hand.
Choose a palette to preview it.
Features / Analyst
A single map gives you the weather at a glance. Analyst adds reflectivity, velocity, spectrum width, and differential reflectivity so you can investigate possible rotation without losing your place.

Level 2, every tilt
HookEcho decodes the raw Level 2 volume from the radar itself: every elevation angle in the scan, at full range and full gate resolution, not a pre-rendered image of the lowest tilt. Step up through the tilts to see how a storm leans, or put four of them on screen at once.
Velocity and dual-pol
Velocity with dealiasing and a storm-relative view for spotting couplets, plus the full dual-polarization set — ZDR, CC, KDP and differential phase. Compare products at the same location and time; a single color or signature does not confirm a hazard.
The whole country
The national MRMS mosaic at full resolution, with the derived grids that come with it: rotation tracks showing where a mesocyclone has been, MESH hail size, and QPE rainfall totals for the flooding question.
Warnings and alerts
Watches, warnings, and Special Weather Statements open in a clear glass card with the official bulletin already visible, scrollable, and ready to read aloud. Spoken warnings and emergencies cover the area within 30 miles of your Home location, with emergencies taking priority. Follow storm reports as they come in and spotter positions — drawn on the map rather than buried in a list. Set a rule for your own location and the app tells you when a polygon covers it.
Storm interrogation
Every cell in view, sorted by a severity score built from ProbSevere, rotational velocity and hail size, so the one worth watching is at the top. Click one for its history, or cut a vertical cross-section straight through it to find the overhang and the BWER.
Models and soundings
Model fields drawn over the same map as the radar, with Skew-T soundings and the severe composite parameters — CAPE, shear, STP, helicity — so the forecast and the radar are one screen instead of two tabs.
Tropical
Hurricane forecast tracks and cones from the National Hurricane Center, with the advisory first in a polished glass reader—official text remains immediately visible and scrollable—over the same radar you use for everything else.
Archive and offline
Scrub back through the NOAA archive to any volume since 1991 and replay an event with its warnings and reports time-synced. Or build an offline chase pack ahead of time, for the part of the day when the data connection is the thing that fails.
On Android
Not a stripped-down companion app: the Android build reads the same Level 2 volumes and draws the same products, with a layout built for one thumb. Home-screen widget, quick settings tile, and warning notifications for where you actually are — which, when you are chasing, keeps changing.
