The Bureau of Meteorology says a tropical low in the Gulf of Carpentaria is running out of time to transform into a cyclone.

The system is forecast to cross the coast around Port McArthur sometime today between noon and early afternoon.

It will track south-west through Borroloola and Robinson River and then head towards communities in the west of the Northern Territory and the Kimberley.

Patch Clapp from the Bureau says whether or not the system becomes a cyclone, it is expected to bring windy conditions and potentially locally intense rainfall.

Since 9am yesterday Bourketown has received 135ml of rain and there are flood warnings for the southern gulf rivers and Carpentaria rivers on the Northern Territory side of the border.
