Tropical Low 13U
A tropical low (13U) may form in the Gulf of Carpentaria, and is a Low risk of developing into a tropical cyclone.

• The monsoon flow across the Gulf of Carpentaria may drive the formation of a tropical low (13U) later this week.
• If it forms 13U will most likely remain weak over the Gulf of Carpentaria waters or near the western Peninsula.
• It is a Low (5-10%) risk of developing into a tropical cyclone Friday and over the weekend.
• If the other tropical low (12U) moves towards western Queensland or the southern Gulf of Carpentaria, it is likely that 13U will have already weakened.
