The longest dry spell recorded at the Alice Springs airport has been broken.
It had not rained there since April, but three millimetres of rain fell overnight on Thursday.
Senior forecaster Ashley Patterson says a cloud band had moved over the area.
"The previous record was 147 days in 1972 and we've actually recorded 157 days without rain at Alice Springs airport," she said.
"The long, long dry spell has been broken."
