Forecast issued at 4:30 am EST on Saturday 8 March 2014.
A developing tropical low over the northeast Coral Sea is expected to move to the south southwest during the weekend and is likely to approach the Herbert and Lower Burdekin coast late on Sunday. Another developing tropical low lies in the north of the Gulf of Carpentaria and is expected to move towards the southeast over the weekend, approaching the west coast of the Cape York Peninsula late on Sunday. Forecasts over the weekend and early next week for the central coast and tropical northern Queensland will be highly dependent on the development and movement of these lows. A high will move slowly eastwards over the Tasman Sea during the weekend and early next week, maintaining a firm ridge along the southern east coast. An upper trough over central Australia will approach the southwest of the state today and move east across the southern interior on Sunday, maintaining weak instability over southwestern Queensland.
Forecast for the rest of Saturday
Scattered showers about the tropical and central east coast are expected to increase to areas of rain late in the day with showers extending to the adjacent inland areas during the evening. Showers and isolated thunderstorms about the far north of Cape York Peninsula with areas of rain with scattered showers and isolated thunderstorms elsewhere about the Peninsula district. Isolated showers about the southern east coast and the Capricornia coast. Isolated showers with possible thunderstorms about the southwest of the state. Moderate southeast to northeast winds about the interior. Strong and gusty southeast winds about the tropical and central east coast increasing further during the evening. Moderate southeast winds in the southeast.
Fire Danger - High to Very High in the central and southern interior.
Sunday 9 March
The low or tropical cyclone in the Gulf of Carpentaria is expected to continue to move to the southeast, whilst the low or tropical cyclone in the Coral Sea should continue to move to the south southwest and approach the Herbert and Lower Burdekin coast. Forecasts are highly dependent on the development and movement of these tropical systems. Rain areas and possible thunderstorms with some heavy falls are likely about the east tropical and central coasts and adjacent inland areas between about Cairns and St. Lawrence. Showers and patchy rain areas will also extend further inland into the eastern tropical interior. Scattered showers and isolated thunderstorms about the northern tropics with rain areas about northern Cape York Peninsula. Local heavy falls area possible about the north of Cape York Peninsula. Isolated to scattered showers about the southeast of the state in the freshening onshore flow. Isolated showers and thunderstorms are possible about the southwest of the state. Damaging winds about the east coast from Cairns to St. Lawrence and also about the west coast of Cape York Peninsula and the Torres Strait Islands. Mostly sunny over the central interior.
Monday 10 March
Forecasts remain highly dependent on the development and movement of the tropical systems off the northeast tropical coast and in the northern Gulf of Carpentaria. Rain areas and possible thunderstorms with some heavy falls are likely about the east coast and adjacent inland between about Cardwell and St. Lawrence. Showers and rain areas are also likely to extend further inland into eastern parts of the southern tropical and central interior. Scattered showers will occur further south along the east coast in an onshore wind flow, assisted by a weak upper trough moving north from New South Wales. Scattered showers and thunderstorms will persist elsewhere in the north of the state with rain areas likely to persist about the far north of Cape York Peninsula. Mostly sunny conditions over the west of the state and the southern interior.
Tuesday 11 March
Forecasts continue to be highly dependent on the development and movement of the tropical systems. The high in the Tasman Sea should maintain a ridge along the southern east coast. At this stage it is likely rain areas and possible thunderstorms will continue about the central coast and adjacent inland as well as the Herbert and Lower Burdekin district with some heavy falls possible. Isolated showers will continue about the southern east coast and adjacent inland in the onshore flow. Fine and mostly sunny in the west of the state and the southern interior.
Wednesday until Friday
Forecasts during the outlook period remain highly dependent on the development and movement of the tropical systems. At this stage it is most likely there will be an easing in rain and showers about the central and northeast tropical coasts as the tropical systems shift further to the east over the Coral Sea. Isolated showers will continue about the east coast as the onshore flow is likely to continue. Fine and mostly sunny conditions should continue in the west and about the southern interior.
The next routine forecast will be issued at 4:30 pm EST Saturday.
