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 colours and symbols used on the radar and satellite maps are described on our legend page. View legend »

Radar Details

Esperance Weather Watch and Windfinding Radar
Western Australia
33.8170°S  121.8330°E  25m AMSL

LocationEsperance Meteorological Office Radar TypeWF 100 C Band Typical Availability2100-0001; 0130-0700; 0900-1300; 1430-1900

The Esperance Radar, which has its antenna mounted on 10 metre tower, thus providing coverage from 40 metres above sea level (M.O. at 30 metres ASL), has an unrestricted 360 degree view with no permanent echoes. Some anomalous propagation (AP) may occur within 20 kilometres of the radar site and provides a radar image of echoes appearing to dance around the station. When very hot conditions combined with northerly winds exist, speckled AP may be observed. During early mornings, in conditions of very low temperature, areas of AP may also appear, mainly to the east of station. The radar has an effective range beyond 250 kilometres and therefore thunderstorms can be seen further out than Norseman and Balladonia and approaching cold fronts from the south-west may be observed as they pass through Bremer Bay. 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.
