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.
LocationHervey Range Radar TypeDWSR 2502 C band Typical Availability24 hours
Interpretation Notes: The site at Hervey Range is at elevation (590m) making it a fairly good site for Townsville's main weather watch radar. It does however suffer some obstruction to its view due to the higher terrain around the region. Mt Elliott (1234m) lies approximately 40km to the ESE and considerably restricts the radar's ability to see light to moderate precipitation echoes in that direction. The Hervey Range itself to the west and the Paluma Range to the northwest can obscure early development of thunderstorms, but fully developed storms are picked up well. SE trade wind showers are common along the coast during the dry season and the radar's range for these extends from offshore Innisfail to Bowen. It is possible that coastal locations between these towns and locations inland of Ingham may experience light to moderate showers that are not picked up on the Hervey Range radar, that might be detected by the adjacent radars at Bowen (Abbot Point) and Cairns (Saddle Mountain). Very distant showers in the Coral Sea may also not be better detected by these adjacent radars due to their superior ocean outlook. Low level drizzle can also go undetected due to the radar beam going over the top of the precipitation. Heavy rain over the radar site will cause attenuation of all signals. 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.
14:30 EDT It will be beach and BBQ's for some, cool and cloudy for others...
