On Friday 31 January 2020 at approximately 2pm, Port Lincoln experienced an extreme rainfall event resulting in flash flooding throughout the entire city. The event was caused by a weather pattern that included a monsoonal trough extending from the Northern Territory that was picked up by a cold front passing through South Australia. The thunderstorm pattern was very isolated with many areas on the Eyre Peninsula recording little or no rain.
Port Lincoln experienced the brunt of this rainfall event. The information on the rainfall intensity and duration suggests that the majority of the rainfall occurred within a ½ hour to hour long period between 2 and 3pm. Additional showers were experienced through to approximately 4.30pm. Rainfalls of 50-60mm within this period were reported by numerous residents. The best available data suggests that approximately 60mm of rain was recorded within the hour and up to 75mm in 1.5 hours.
Council would like to acknowledge the District Council of Lower Eyre Peninsula, the District Council of Tumby Bay, CFS and Department for Environment & Water who immediately offered assistance to SES, MFS, SAPOL and other emergency services by providing ground crew and administrative support during Friday's flash flood event. Many local businesses also went above and beyond to offer their expertise and service.
Their support was invaluable and much appreciated by our Council staff and the combined efforts of all emergency services and the community was outstanding.
