I talked about this winter in the ENSO thread but it can be repeated a little here.
The La Nina going two, and looks like three years running, is creating a lot of rain and cooler temps for Australia.
This is great for plant growth.
What this equals is fuel for the fires later on.
When I think about the Black Summer, which was a neutral year, I dread to think what will happen when the La Nina ends... and I am dreading the next El Nino.
The fires, when the ENSO cycle ends La Nino, are going to be catastrophic. Last time we mostly avoided cities, several towns disappeared, so many animals died it is beyond counting.... and I honestly think we got lucky in Sydney that the fires didnt break into the city properly.
I, personally, dislike relying on luck because it has a nasty habit of ending.
I sort of wish the La Nina would end asap to reduce the fuel levels for what is to come here.
