Colour Isobars connect equal pressure readings (iso = equal, bar=barometer) There are stations all over the globe which, either with a human or a machine, register what the pressure is at that spot. Bushfires can start and change direction very quickly. They define the average pressure of a given point at sea level and 59°F (15°C) as one atmosphere or 1013.25 millibars. In weather terms, this means the pressure pattern, fronts, wind direction and speed and how they will change and evolve over the coming few days.

Our community includes people of all ages and backgrounds and we want this to be a safe and respectful environment for all. The weather map, also known as a synoptic (summary or overview) chart, is a simple representation of the weather patterns at the Earth's surface, showing the locations and movements of the different systems. The station model is primarily used on surface-weather maps, but can also be used to show the weather aloft. Australia Weather Radar map provides latest rainfall conditions across Australia.
