THE climate phenomenon responsible for rain over summer appears to have reached its peak.
Meteorological company, The Weather Channel, said La Nina had steadied since December and was expected to weaken further in coming months.
Senior meteorologist Tom Saunders said he was confident the current La Nina event was peaking.
"The Southern Oscillation Index has dropped significantly from +24 in late December to +13 by January 15," Mr Saunders said."This evolution is consistent with past events, in which La Nina becomes strongest and most well defined during late spring and summer, before weakening in autumn."
But Mr Saunders said heavy rain and flooding would still remain a threat over the coming months as La Nina conditions continued until autumn.
