A tropical low moving through the Arafura Sea and another in the Coral Sea have become better organized in the past 24 hours.
Both areas of low pressure have the potential to become named tropical cyclones in the coming days as they approach Queensland.
The low over the eastern Arafura Sea will take a southeast track reaching the northwest coast of the Cape York Peninsula Sunday night.
Heavy rain will fall across the Cape York Peninsula leading to flash flooding. Rainfall amounts of 50-100 mm (2-4 inches) are expected with locally higher amounts. Winds of 60-80 kph (40-50 mph) will batter the coast from Kowanyama to Mapoon.
The storm will then weaken as it crosses the Cape York Peninsula, but it could reemerge into the Coral Sea early next week with the potential to reorganize.
The tropical low currently over the open Coral Sea to the east of Cairns is also expected to become a named tropical cyclone in the next day or two.
This storm will track westerly through Saturday before turning sharply to the south. This track will keep the storm off the coast through the weekend.
The storm will likely approach the central coast of Queensland on Monday bringing locally damaging winds near Townsville to Mackay. Flooding will also be a threat as heavy rains are expected over the same regions.
This storm may stall offshore from Sunday through Tuesday leading to several days of locally heavy rainfall. The storm will then likely turn and track back to the northeast away from coastal Queensland by the middle of the week.
Due to the slow movement of this storm near the coast, rainfall amounts of 100-200 mm (4-8 inches) will be possible with locally up to 300 mm (12 inches)
