La Nina or the Southern Oscillation Index aided by a warming planet. This flood peak is 2 metres higher than the previous worst flood in Lismore, that is not a small amount.
There are 50 people waiting to be rescued from their rooftops in a town south of Lismore and hundreds stranded on bridges etc.
These rescues take time because each roof space has to checked for people taking refuge there.
Flood warnings have been issued for virtually the entire eastern coast line as the rain moves south currently Sydney and the Illawarra warning is for “heavy to torrential rain” this afternoon and tomorrow.
There is no clear sign if the east coast low will form or where, computer modelling is unclear (according to the Bureau this morning)
It looks like the Illawarra has dodged a bullet with the East Coast Low hitting the coast north of Sydney. There has been a lot of local flooding but mainly where expected Macquarie Pass is still closed as well as many schools.
The railways are in trouble because the lines are flooded in various places but the trains have been replaced by buses
Having said that it is still raining and there is the change of thunderstorms, all this water has to go somewhere because the ground can’t take any more. The extra high tide is due just after 9am which will push water back up the creeks and rivers.
