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.

LocationEucla Meteorological Office Radar TypeWF 100 C Band Typical Availability2100-0700; 0900-1300; 1430-1900
There are no permanent echoes associated with the Eucla radar. During Summer, with moderate to heavy sea haze thrown up by the afternoon sea breezes, there may be quite heavy echoes developed up to 50 kilometres out to sea extending from ESE to SW. Any approaching weather, generally from the SW through to the NW, usually has well defined echoes at up to 300 kilometres range. Thunderstorm and rain areas associated with troughs during Spring and Summer are quite noticeable and easily tracked. Heavy rain directly over the radar site can cause attenuation of all signals. Path attenuation can also occur when the radar beam passes through intense rainfall, with the returned signals from cells further along that path reduced.
