MELBOURNE - Apr 30/13 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.
Warning Summary at issue time A Tropical Cyclone Warning is current for coastal areas from Orford Ness to Cape Tribulation. A Tropical Cyclone Watch is current for coastal areas from Mapoon to Orford Ness, including the Torres Strait Islands. Wind Warnings are current for coastal waters north of Cardwell. A Preliminary Flood Warning has been issued for coastal rivers and adjacent inland streams between Thursday Island and Cape Tribulation. For the latest warning information please check the Bureau's web site www.bom.gov.au/qld Weather Situation At 4am EST, Tropical Cyclone Zane [983 hPa] was located 550 kilometres east southeast of Lockhart River and moving west at about 12 km/h. Tropical Cyclone Zane is expected to move west northwest over the next 24 hours, most likely crossing northern Cape York Peninsula early on Thursday. A firm ridge of high pressure extends along much of the east Queensland coast. Forecast for the rest of Wednesday Squally showers and thunderstorms increasing over areas northeast of about Weipa to Cape Tribulation with heavy rain areas developing from the east during the afternoon and evening. Scattered squally showers over the east tropical coast from about Cape Tribulation to Ingham. Scattered showers decreasing to isolated over the remaining east tropical and central coasts during the day. Isolated showers over remaining eastern districts and also extending through the central interior and eastern Gulf Country during the day. Fine and mostly sunny over the remainder of the state. A cool day through the far northern tropics under the cloud cover and rainfall. Winds increasing over the far northern tropics - refer to Tropical Cyclone Advice for TC Zane. Moderate SE to NE winds elsewhere. Forecast for Thursday At this stage, Tropical Cyclone Zane is expected to cross the Cape York Peninsula coast near Lockhart River in the early hours and then weaken as it shifts west into far northern parts of the Gulf of Carpentaria during the day. Squally showers, storms and heavy rain areas should gradually decrease over the northern Peninsula district as Tropical Cyclone Zane weakens and shifts west. An upper level trough is expected to intensify over southeastern Queensland, increasing instability. A surface trough and an associated fresh to strong S'ly wind change will most likely move north along the New South Wales coast and enter southern Queensland waters during the day. The combination of the unstable airmass and this surface trough should result in isolated showers increasing to scattered over the southeast of the state during the day, particularly near the coast and ranges, with isolated thunderstorms developing. Isolated to scattered showers will occur along the remaining east coast and tropics in a moist onshore wind flow. A new high will move east into southeastern Australia, maintaining a firm ridge and fresh to strong SE'ly winds over the northeast tropical coast. Fine and mostly sunny conditions will continue over remaining parts of the state. Forecast for Friday The upper trough will shift north into the Coral Sea while the surface trough will also shift north and weaken during the day. Instability will therefore decrease over the southeast of the state with only isolated showers expected. The new high will shift northeast through New South Wales towards our southern border, extending a firm ridge and fresh to strong SE'ly winds over the east coast north of about Fraser Island. This moist, onshore wind flow will result in isolated to scattered showers along the coast, with possible thunderstorms through Torres Strait. The ridge will also result in dry and stable conditions through the interior of the state. Forecast for Saturday The high near our southern border will weaken, contracting strong SE'ly winds to waters north of about Cardwell. Isolated showers should clear central and southern coasts during the morning as a drier airmass extends north. Isolated to scattered showers will persist through northeastern Queensland and near the southern Gulf of Carpentaria coast. Fine and mostly sunny conditions are expected through the interior of the state, with a cold morning likely over the southeast inland. Outlook for Sunday, Monday and Tuesday The high should begin to weaken late in the weekend as a new upper trough moves east over southern Queensland early next week. The upper trough, in combination with an onshore wind flow, will possibly lead to an increase in showers about the east coast during the outlook period, which may extend in to the central and southern interior on Tuesday. The next routine forecast will be issued at 4:10 pm EST Wednesday.
