Weather Alert | Date: 28 February 2025  

Rainfall is predicted over the next week

A cyclone has formed off the coast of Queensland influencing the weather on the Sunshine Coast. While it's likely the cyclone will remain off the coast, an increase in wind is likely, with possible heavy rain showers over the next week. Some of which could be intense in nature. 

Due to the unpredictability of this type of weather event it is difficult to accurately forecast rainfall amounts. Although the rainfall amounts forecast for the early part of next week has now been reduced, this could change if the cyclone alters course and travels nearer to our region. The later part of the week is also still uncertain with there being a possibility of large rainfall amounts.

As a contractor/developer, it is your responsibility to remain up to date with weather forecasts and to comply with the General Environmental Duty to ensure that your site is ready for any adverse weather.

Updates on any weather warnings can be found at Queensland Warnings Summary - http://www.bom.gov.au/qld/warnings/. The cyclone forecast can be found at Bureau of Meteorology - http://www.bom.gov.au/cyclone/.

Is Your Site Right? Do these quick checks

Now is the time to think about, 'Is Your Site Right'? How will you prepare your site to make sure the water coming off your site during the rain event is under 50mg/L? 

Some ideas for quick checks are outlined below.
 
For all sites:
  • Consult your ESC Plan for site specific contingency measures to be enacted.
  • Is the maximum area of land stabilised? Remember polymer soil binders should be sprayed 24 hours prior to rainfall.
  • Are all controls in good working order and don’t require maintenance?  For example, ensuring ESC devices are free from silt and material to increase capacity. 

If your site is steep:
  • Have you inspected and reinstated controls to manage slope length?
  • Are drains stabilised to convey expected flows (e.g. rock, geofabric)?

If you are working in a watercourse or drainage line through your site:
  • Is the diversion drain of sufficient size and stability to convey expected flows?
  • Has the work area been stabilised (e.g. geofabric) so that water can flow through without causing damage? 

If you have Type D (batch) sediment basin:
  • Have you treated and discharged detained water to allow for maximum storage capacity for rain event?
