Installation

  1. Deactivate/remove an older development copy before installing a replacement build when WordPress requires it.
  2. Go to Plugins > Add New > Upload Plugin.
  3. Upload the Storm Tracker ZIP and activate it.
  4. Go to Settings > NWS & NEXRAD Storm Tracker.
  5. Configure radar, basemap, and Placefiles.
  6. Place [storm_map] on the desired page or post.

Placefiles

Placefiles are configured under Settings > NWS & NEXRAD Storm Tracker > Placefiles & Shapefiles.

The renderer supports common GRLevelX/GR2Analyst commands including icons, icon files, text, lines, polygons, objects, colors, fonts, refresh intervals, and dynamic feed URLs.

Some providers require a GRLevelX Placefile manager and may not return drawable objects to an ordinary HTTP request. A feed that returns only its header may therefore have no active objects or may require a specialized request.

Storm Cells

Storm Cells use MRMS ProbSevere information. Their appearance can change according to available probability and threat information. The Storm Map Key uses purple to identify Storm Cells.

Third-Party Data

The plugin uses or can display data/services from NWS, RainViewer, Iowa Environmental Mesonet, MRMS/ProbSevere sources, OpenStreetMap, CARTO, Leaflet, Leaflet Control Geocoder, shpjs, Spotter Network, and GRLevelX-compatible Placefile providers. Provider availability, coverage, refresh rates, and terms are controlled by those providers.

Troubleshooting

Placefile says 0 objects

A Placefile may legitimately return only a header when there are no active objects. Some feeds also require a GRLevelX Placefile manager.

GLM Lightning is slow

Large GLM icon sets are rendered using a canvas-based approach to avoid creating thousands of individual HTML markers.

jQuery Migrate warnings

JQMIGRATE messages are WordPress compatibility warnings and are generally separate from the Storm Tracker Placefile diagnostics.

Safety Notice

Do not rely solely on this Plugin for making life-safety, travel, or critical operational decisions.

For warnings and emergency decisions, use official National Weather Service information and local emergency-management instructions.

Version 2.0.50

  • Fixed paused NEXRAD radar so the slider stays on the newest available 5-minute frame.
  • Paused NEXRAD radar now automatically advances to the newest frame when a new scan arrives.
  • Prevented repeated radar-layer replacement when the newest radar timestamp has not changed, reducing unnecessary screen flashes while paused.

  • Updated the plugin version and readme files to 2.0.50.

Version 2.0.49

  • Spotter Network markers are now displayed as small red dots so they are easier to distinguish from other Placefile layers.

  • Preserved the Placefile popup/tap interaction improvements from 2.0.48.

Version 2.0.48
