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:
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.
LocationYarrawonga Radar TypeWSR 81C C Band Typical Availability24 hours
The Yarrawonga radar has a very good view in all directions and is the primary weather radar for Northern Victoria, which includes the Goulbourn Valley. It should provide useful weather information as far south as Marysville, west to Bendigo and north to Griffith. The advantage of the "C Band" radar is that it is better at detecting smaller drops so therefore performs better in light rain situations. The Yarrawonga radar has a greater ability to resolve thunderstorms in the summer months when echoes are generally larger. Being a "C Band" radar, if there are large thunderstorms in the area, the radar may not be able to determine accurately the strength of additional storms located behind the closest storms. False echoes can be sometimes observed very close to the radar especially in stable conditions. These are normally easy to distinguish because they are usually of the lowest intensity level and are very small and randomly scattered. Echoes within approximately five kilometres of the radar and overhead can be poorly resolved as the scanning elevation is too low.
