South Faces Heavy Rain and Strong Winds as Weather Worsens

A new wave of severe weather is set to impact the southern regions of New Zealand, bringing with it strong winds and heavy rainfall. Following a weekend of significant rain across much of Otago and Southland, authorities are once again preparing for challenging conditions.

Over the weekend, heavy downpours led to surface flooding and road closures in various areas. The Dunedin City Council reported that a section of Old Brighton Road is currently closed due to flooding. Similarly, the Clutha District Council announced that Greenvale Road is also impassable because of high water levels. Local authorities have advised that surface flooding could persist on roads, urging motorists to drive cautiously and remain aware of changing conditions.

As of this morning, MetService has issued an orange heavy rain warning for the headwaters of the Otago lakes and rivers, effective from noon until 20:00 on March 11, 2024. Forecasters predict that the main divide could receive between 60 to 80 mm of rain, while areas further east may see 50 to 60 mm within a 15-kilometer radius. Rainfall rates are expected to peak at 10 to 20 mm/h around the divide, with snow levels forecasted to sit at approximately 1,800 meters.

In addition to the rain, a strong wind watch is in place for several locations including the Queenstown Lakes District, Central Otago, and the Clutha District north of Tapanui and Southland north of Riversdale. This warning will be active from 11:00 to 20:00 on March 11, 2024, with strong northwest winds potentially reaching severe gale force in exposed areas.

The unsettled weather is expected to continue into Tuesday, March 12, with additional rain and snow possible, with snowfall potentially reaching as low as 600 meters in the southern regions.

Relief may be on the horizon as forecasts indicate improving weather conditions later in the week. By midweek, residents can anticipate clearer skies and rising temperatures, with highs potentially reaching the early 20s Celsius across most of Otago.

As the region braces for the upcoming weather, local authorities and residents are advised to stay informed and prepared for changing conditions.
