Severe Storms and Heavy Rain Threaten Brisbane and Australia’s East Coast

Severe storms and heavy rain are set to impact Brisbane and Australia’s East Coast this week, potentially alleviating a dry spell in southern Queensland and New South Wales. Forecasts indicate that some areas may experience significant rainfall as humid conditions linger across the region.

Weather Overview

This week has been characterized by excessive humidity, especially in Brisbane, where temperatures have matched those of Darwin. A cool change is sweeping through the southeast and central parts of Australia, colliding with the tropical moisture that has settled over the area.

Storm Warnings Issued

Severe thunderstorms threaten the North Coast and ranges of New South Wales on Thursday afternoon. As the day progresses, the storm activity will move into southeast Queensland, raising concerns for heavy rain, damaging winds, and large hail.

Potential Rainfall in Brisbane

Brisbane has recorded just over 130mm of rain this summer, considerably below its average of 444mm. The upcoming storms are expected to initiate heavy downpours, with forecasts predicting that Brisbane and the Gold Coast could receive between 100mm and 300mm of rain over the weekend. This rainfall could result in flash flooding in local areas.

• Rainfall Forecast
  • Brisbane: 100-300mm
  • Gold Coast: 100-300mm
• Flood Watch
  • Minor river flooding anticipated
  • Potential for isolated moderate flooding

Despite concerns of flooding, the recent dry conditions are expected to mitigate severe impacts along the rivers, particularly concerning the Brisbane River which should remain within safe levels.

Regional Impacts

On Friday, southeast Queensland will see thick clouds and persistent rain. The NSW North Coast can expect lighter showers and isolated storms. Increased rainfall is anticipated in northern New South Wales as the weekend progresses, with some areas in southern Central Highlands likely to see totals approaching 100mm.

Conclusion

This weather event, influenced by the current La Niña conditions, is expected to significantly benefit Queensland. However, many drier regions in New South Wales will likely continue to miss out on this rainfall, further exacerbating conditions in those areas.
