Lightning Data Upgrade - NEW

Lightning Events

lightning Lightning strikes are displayed as crosses (ground events) or squares (cloud events) and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).

In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:

  • Much better detection of cloud to cloud strikes. Our upgraded network detects more CC strikes and better reflects research that shows typical storm cells produce approximately 75% cloud strikes and 25% ground strikes.
  • We have modified the display to show cloud to cloud strikes in smaller boxes and ground strikes above as "+" symbols. Temporal colouring remains the same.
  • Greater network coverage right across the country.

About Weatherzone Radar

distance measuring Distance and latitude/longitude coordinates are displayed when you mouse over the map. The origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.

The Grafton radar has a very good view in all directions and is the primary weather radar for the North East of NSW. It should provide useful weather information as far west as Glen Innes, south to Kempsey and north to the Gold Coast. There is a tendency to observe areas of false echoes within approximately 100 kilometres of the radar over the sea. These are normally easy to recognise because they are usually the lowest intensity level and randomly scattered with erratic movement from one radar scan to the next. True rain echoes normally have a consistent direction of movement from one scan to the next. Due to its location, this radar is often unable to detect light showers or drizzle beyond a range of 100 kilometres. Although largely removed from the display, anyone to the south west of the radar (50 kilometres or more from Grafton) may find an occasional false echo generated by the mountains in this region. There is a small blind spot within a few kilometres of the radar.
