A cyclone predicted to form tomorrow could brew up stormy activity for the Top End but isn't likely to do much more than that, the weather bureau has said.

The bureau is monitoring a tropical low about 1000 kilometres northeast of Cairns, in the far northern Coral Sea.

Senior forecaster Stephanie Bond said the low had a high chance of brewing into a tropical cyclone tomorrow.

She said it was likely to move towards the Northern Territory on Wednesday.

"They don't have any official forecast track out currently," Ms Bond said.

"But they are keeping a close eye on it.

"They're just saying there's a high chance in the tropical cyclone outlook that it will form into a tropical cyclone some time on Tuesday."

She said it could bring increased showers and storms over the Top End this week.

But she said it would weaken as it headed towards the Top End.

"By the time it gets over to our side of the Gulf of Carpentaria, it has all disappeared and it's only a little bit of a trough," Ms Bond said.

"So we're just going to see increased shower and storm activity over the north and eastern Top End Gulf country from Wednesday."
