A tropical low over the eastern Gulf of Carpentaria strengthened on Monday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Penny. The circulation around Tropical Cyclone Penny was still organizing. A band of showers of showers and thunderstorms wrapped around the western and northern sides of the center of circulation. Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Penny. Storms near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.
Tropical Cyclone Penny could strengthen during the next few hours. Penny will move over water where the Sea Surface Temperature is near 30°C. It will move through an area where the upper level winds are weaker and there will be little vertical wind shear. Tropical Cyclone Penny will make landfall on the Cape York Peninsula near Weipa in about 12 hours. Penny will weaken while it crosses northern Queensland. Tropical Cyclone Penny could strengthen again when it moves over the Coral Sea in 24 to 36 hours.
Tropical Cyclone Penny will move south of a ridge centered northeast of Australia. The ridge will steer Penny in an east-southeasterly direction. On its anticipated track Tropical Cyclone Penny will make landfall on the Cape York Peninsula near Weipa in about 12 hours. Penny could emerge over the Coral Sea south of the Lockhart River in 24 to 36 hours.
Tropical Cyclone Penny will bring rain and wind to the west coast of the Cape York Peninsula. Penny will drop locally heavy rain over parts of northern Queensland. The heavy rain could cause flooding. A Flood Watch is in effect for coastal catchments north of Caldwell, Australia and the Cape York Peninsula.
