United States Radar Map
Track the weather via NEXRAD
3
Connections
A simple way to display radar imagery with a lot of additional overlays like storm tracking, wind, temp, and warnings. It's based on available NEXRAD and IEM, through NOAA, and is limited to coverage of the continental United States, Alaska, Hawaii, Puerto Rico and Guam. Areas outside of that radar coverage will not see weather data.
Available settings
Location
Search for a city, address or postal code, or enter coordinates (e.g. 38.9072,-77.0369). The map is centered here.
Place Label
Shown in the title bar (e.g. Northern Virginia).
Zoom
How much ground the map covers.
Show keys?
Show the map keys, or hide them for a clean map. Alert lists and watch tags still show.
Show radar scan age?
Show how old the radar scan is, with an 'OLD DATA' tag when it is more than 30 minutes old.
Show all 15 options
Show city labels?
Label cities on the map.
Show interstates?
Draw interstate highways to help with orientation.
Show county lines?
Draw county lines. May get cluttered as you zoom out.
Show temperature and wind?
Show current temperature (°F) and wind (arrow showing where it blows, speed in mph). Uses Open-Meteo's model analysis which is updated every 15 minutes.
Show storm motion arrows?
Uses NEXRAD storm tracking to draw an arrow on each tracked storm cell showing where it will be in about 30 minutes.
Show severe storm marks?
Mark storm cells NEXRAD flags as dangerous: a triangle for a tornado vortex signature, a ring for rotation, and a diamond for potentially large hail.
Rotation marks
Adds ring marks for storms the radar identifies as rotating. Most rotating storms never produce a tornado, so you can select 'Strong only' to only mark rotations that the New Mesocyclone Detection Algorithm rates 5 or higher. Applies only while Severe Storm Marks is on.
Show warning polygons?
Outline active NWS storm-based warnings.
Show warnings and advisories?
List the NWS warnings, watches and advisories in effect at your coordinates, and outline the county alerts IEM draws (severe, tornado, flood and winter types).
Show watches?
Outline Storm Prediction Center tornado watches (thick dashes) and severe thunderstorm watches (dots).
