Good to know

  • Radar, lightning and the airport reports are measured; temperature and wind come from a forecast model for the nearest hour, so a thermometer in San Juan, Texas can read differently.
  • Radar detail stops at about zoom 7 and lightning at zoom 8, so the weather of a single street isn’t resolved.
  • Use it to see conditions, not to make safety decisions; for those, follow your local weather service’s warnings.
