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.
LocationMt Bassett, Mackay Harbour Radar TypeWF 44 S Band Typical Availability0000-0915; 1030-1515; 1630-2115; 2230-0000
Mackay radar has a good view of the surrounding area and is rarely affected by anomalous propagation. Some permanent echoes occur to the north and west. Showers in the SE trade wind flow are generally well picked up but when they are restricted in height the range of detection decreases so that showers around the Whitsunday Islands and northward can be under-represented. Generally the radar's range for coastal showers extends from about St Lawrence to Bowen. Path attenuation also occurs when the radar beam passes through an intense thunderstorm cell; the returned signal from cells further along that path will be reduced. Apart from these features, the radar performs well and gives a reasonably accurate representation of rainfall intensity. During episodes of fresh to strong winds (>20kt or 38km/h) sea clutter can be seen up to 30km from the coast possibly masking light inshore showers.
