Australia Stormtracker

Stormtracker allows you to view different elements of current weather on the one display.

Lightning strikes are displayed as crosses and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).

Surface observations are displayed as a 'rose' with temperature, dew point and relative humidity down the left-hand side and rainfall since 9am, pressure and location name displayed down the right-hand side.

Temperatures fade in colour from blue (cold) to red (warm) and dew points fade in colour from blue (moist) to red (dry).

You may change the display between static (latest) and animating using the 'display' option. An animating display shows the closest data available to each of the past 3 hours.

On radar and sector pages distance and latitude/longitude coordinates are displayed next to the time stamp 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.

Sentinel hotspots detected within the last 24 (or 48) hours are displayed. Sentinel is a satellite-based national bushfire monitoring system operated by Geoscience Australia.

* Locations discovered using the W3C Geolocation API (limited browser support) are used only for positioning the dot and are not stored in any way.
