Interpreting Data
What do wind charts show?
In the computer models section, there are forecast wind charts available at a whole variety of resolutions and height levels. These charts are showing the predicted strength and direction of the wind at that level of the atmosphere.
The wind is blowing from the direction where the barbs on the wind stick are pointing, to the empty end of the wind stick. Each full barb represents 10 knots and each half barb 5 knots. A triangle completely shaded in represents 50 knots.

A very wet weekend for southeast Qld, northeast NSW
11:48 AEST A prolonged rainfall event is set to bring large totals to parts of NSW and Qld from Saturday, with possible heavy falls and flooding. A low-pressure system in the Coral Sea, a deepening coastal trough and persistent easterlies will bring moisture-laden air into southeast Qld and northeast NSW will bring days of rainfall to the region. While there is not a drop of rain on the radar over southeast Qld and Northeast NSW on Friday morning, the mass of cloud associated with a low in the Coral Sea will enhance rainfall over the weekend.
