Australia: Adverse weather forecast for parts of eastern Queensland through at least Nov. 21

Severe weather is forecast across parts of eastern Queensland through at least Nov. 21. A coastal trough is expected to bring heavy rainfall to parts of the central coast around Mackay from late Nov. 20 through Nov. 21, before gradually easing as the system moves inland late Nov. 21. As of Nov. 20, the Australian Bureau of Meteorology (BOM) has issued a severe weather warning for heavy rainfall for parts of the Central Coast and Whitsundays District; affected locations include Mackay, Sarina, and Eungella. Rainfall totals of 25-30 cm (10-12 inches) are possible in the affected area late Nov. 20-late Nov. 21. The heavy downpours may trigger flooding in low-lying areas and landslides on unstable slopes. A marine wind warning for strong winds is also in place for the Mackay coast Nov. 20-21. Strong winds could cause property damage and power outages.

Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed or a lack of stormwater drainage systems. Sites downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rain has saturated the soil.

Floodwaters and debris flows may render further bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation. Severe weather could also trigger flight delays and cancellations at regional airports.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and employees' inability to reach work sites. Electricity and telecommunications service disruptions are possible where significant flooding, strong winds, or landslides impact utility networks.
