For the record, three quarters of the entire state of NSW has been either flooded or was/still is on flood watch these past weeks, along with massive areas of flooding in both Queensland and Victoria. More rain is forecast. Meanwhile, in the west, Perth has sweltered through a record eight heat-waves this summer – that is, eight periods of 3 or more consecutive days over 35 degrees Celsius.
The radar anomalies have still been coming regularly, although they mostly appear as subtle areas and circles of dots, as opposed to the more easily noticed solid or lined circles and beams.
Until today that is, which is interesting, given that the monsoon trough is active again, feeding moisture into a large tropical low that is forming off Western Australia, as well as another tropical system that is forming in the Top End. This means that two tropical cyclones are imminent in the next few days.
Play the loop to see how Geraldton radar looked today:
But the action began sooner in the day, with strong beams coming from Dampier, Wyndham, and somewhere near but not centred on Halls Creek.
The following day, Carnarvon gets into the action too, with a circular anomaly.
One of the two tropical lows has become Severe Cyclone Lua, its crossing is imminent on WA’s Pilbara coastline later today, although it is also affecting large areas of the Kimberly. Alerts and watches reach from Broome all the way down to Dampier and inland to Jigalong. A storm that is comparable in size to last year’s Cyclone Yasi, it is still some 200 km from the coast, is still intensifying and is already a high end category four system.
Play the loop to see Lua’s eye pass nearby the Rowley Shoals out at sea, and how the Learmonth radar at NWC, Exmouth has suddenly begun “glitching”.
And as Cyclone Lua makes its way inland after crossing at remote Pardoo there is this pair of beams from Cairns the following day:
