Australia: Severe weather forecast across parts of northeastern Queensland through at least April 23 /update 1
Severe weather forecast across parts of northeastern Queensland, Australia, through at least April 23. Flooding, disruptions possible.
Event
Heavy rainfall is forecast across parts of northeastern Queensland through at least April 23. As of April 22, the Australian Bureau of Meteorology (BOM) has issued a severe weather warning for heavy rainfall across parts of the North Tropical Coast and Tablelands as well as Herbert and Lower Burdekin forecast districts. The heavy rainfall may result in flash flooding across the northeast tropical coast, between the Mossman and Rollingstone April 22 before extending northwards towards Cape Flattery the evening of April 22. Six-hourly rainfall totals of 15 to 20 cm (6-8 inches) are forecast across the affected area, with higher totals of up to 25 cm (10 inches) likely over the coast and ranges. Locally intense rainfall of more than 30 cm (12 inches) six-hourly totals remains possible through April 23; dangerous and life-threatening flash floods are possible.
A flood watch is in place for the coastal catchments from Ingham to the Daintree; minor flooding is likely from late April 22 with isolated moderate flooding possible. Strong wind warnings are also in effect for the Cairns, Cooktown, Townsville, Mackay, Capricornia, and Fraser Island coasts, the Sunshine Coast Waters, and Hervey Bay through April 23.
Hazardous Conditions
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 located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall.
Transport
Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation. Severe weather could also trigger flight delays and cancellations at airports in the region, including but not limited to Cairns Airport (CNS) and Townsville Airport (TSV). Authorities may temporarily suspend port operations if strong winds and large waves trigger hazardous sea conditions.
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.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Allow extra time for travel in the affected area and plan alternative routes if necessary. Do not drive on flooded roads.
