The weather bureau says a tropical cyclone off the West Australian coast will delay the onset of the monsoon period in the Northern Territory.
The bureau has predicted that Tropical Cyclone Narelle will become a category four cyclone in the next 24 hours.
It is currently offshore from Karatha in north-west WA.
Meteorologist Ben Suter says it means Western Australia will be the focus of monsoonal activity, while the Top End is likely to miss out.
"Having said that, a weak monsoon trough does look close to the north-west coast of the Top End, extending into the Arafura Sea," he said.
"So, once Tropical Cyclone Narelle pulls away a little bit, we might see a few more showers and storms.
"It is not going to be anything particularly heavy, but we might just see a few more showers and storms as we go through the next couple of days.
"Apart from that, we're not expecting any intense monsoon rainfall across the Top End at this stage."
