Preliminary sketch for Convergence Divergence: Peta
Thank goodness for cyclones and the Bureau of Meteorology website. What a plethora of maps and information one can garner when something exciting like wind and rain occur. On January 23rd a tropical low that passed by Port Hedland developed into Tropical Cyclone Peta, which crossed the Pilbara coast as a Category 1 just to the east of Point Samson at around 4pm, roughly in the vicinity of Cossack. So as the rain and wind beat down upon us from outside, I sat at my computer monitoring the event on the myriad of sites that track and trace wind.
