Bureau officially declares El Nino
THE Australian Bureau of Meteorology has officially declared an El Nino in the tropical Pacific.
But what does this mean for Australia?
Typically during El Nino, much of eastern Australia experiences a prolonged drier, hotter winter.
An El Nino can last between three to five months and many in the past have caused widespread drought.
However, the weather bureau says the current May to July outlook suggests much of Australia is likely to be wetter than average because of a warmer-than-average Indian Ocean.
The El Nino is expected to become the dominant influence on Australia climate during the second half of the year.
