The weather bureau says Darwin should experience more rain over the next few weeks.
A storm this morning was one of the most significant downpours in the Northern Territory capital this year, in what has been an unusually dry wet season.
Areas around the Darwin Airport and Marrara recorded falls of up to 100mm in about an hour.
Forecaster Sally Cutter says more wet weather is likely.
"Over the next couple of days, we're going to see the isolated showers and storms continue," she said.
"Whether we actually get them in Darwin will depend on what the wind is doing higher up in the atmosphere.
"We should see a gradual picking up of weather over the next couple of weeks and we are expecting our next monsoon burst towards the end of the month."
