I had a visual of an entire city under a layer of water, trees brought down, houses damaged, raging water pushing away everything in its path.
“Australia.. Brisbane hit hard”
The number 18 could be seen as the 18th of May but more likely its a countdown putting it sometime between the 6th-8th of May.
I would encourage all of those in Australia to please take caution, the visual was very disturbing, the damage it caused was extensive. Though they did not say it, everything points to a cyclone.
