Western Australia Satellite Notes

Bright cloud over WA's Kimberley near a low and trough is producing a few thundery showers. Skies are clearer across the rest of the state with a ridge of high pressure. Thick bright cloud in the Indian Ocean is associated with Tropical Cyclone Kate.

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.
