surface flooding and ponding are anticipated in low-lying areas. Communities can access real-time river level data and flood alerts at the ORC Environmental Data Portal.

Rainfall Varied Across The Region

Coastal Dunedin has experienced the most significant rainfall, with accumulations between 25-50mm overnight. Other parts of Otago received 20-50mm. While rainfall has eased in North Otago, Dunedin could see an additional 20-30mm, and Clutha could receive 30-40mm.

Rivers are rising, prompting close monitoring of vulnerable low-lying areas. These include parts of the Tokomairiro floodplain near Milton, the Lower Taieri floodplain around Henley, the Lower Clutha floodplain, and Middlemarch.

Specific River Forecasts

Officials do not expect the Water of Leith and Lindsay Creek in Dunedin to overtop thier banks.

• The Silver stream near Mosgiel is expected to crest between 90-100 cumecs this afternoon.
• the Taieri River at Outram is forecast to peak this evening between 400-600 cumecs,with flooding likely in unprotected downstream areas.
• The Clutha River at Balclutha is predicted to peak around 1900 cumecs on Sunday morning, with potential flooding in low lying areas and unprotected zones downstream of the township.

Understanding Flood Risks: An Evergreen Perspective

Heavy rainfall events like this highlight the importance of flood preparedness in vulnerable regions. Recent studies indicate that extreme weather events are becoming more frequent due to climate change, increasing the need for robust flood management strategies. Effective strategies include improved drainage systems, construction of flood barriers, and community awareness programs.

Did You Know? The Netherlands,a country largely below sea level,has pioneered advanced flood defense systems,including dikes,dams,and storm surge barriers. These innovations protect the country from North Sea storms and rising sea levels.

For homeowners in flood-prone areas, securing flood insurance and developing a family emergency plan are crucial steps. Keeping up-to-date with local weather forecasts and heeding warnings from authorities can significantly reduce the impact of flooding.

Pro Tip: Create a “go-bag” with essential supplies like water, non-perishable food, a first-aid kit, flashlight, and significant documents. Store it in an easily accessible location for speedy evacuation if necessary.

Staying Safe During A Flood

During a flood event, avoid walking or driving through floodwaters, as they can be deeper and more dangerous than they appear. Stay informed through official channels, and be prepared to evacuate if instructed by local authorities.

Remember, your safety and the safety of your community are the top priorities.
