Sydney low stalls near Auckland bringing thunder, gales & torrential rain (+Maps & Animation)

Updated 7:02am Tuesday — A storm that impacted parts of Sydney last week brought thunderstorms, gales and heavy rain to Auckland overnight – even though the low is no longer a storm.
The low, which has weakened substantially since reaching NZ, is pressing into higher pressure further down the country resulting in windy easterlies (known as a ‘squash zone’) with gusts to gale force in exposed areas through until Tuesday PM. These winds may even increase a little further today before sliding northwards.
This morning the front has stalled over Auckland and after producing torrential falls overnight, it will continue to see enhanced heavy downpours this morning, meaning more localised flooding is possible. For the most part Auckland copes well with heavy rain events, but the rain last night and this morning is possibly the heaviest most sustained rain the city has had in years. WeatherWatch.co.nz head forecaster Philip Duncan says the city has been in a rainfall deficit for over three years now, approaching four years.
Thunderstorms closer to the centre of the low were impacting parts of Auckland last night and due to the slow moving set up the thunderstorms weren’t rushing by as they so often do. Thunderstorms continued for hours last night before easing after midnight. An isolated thunderstorm is still possible this morning with the front stalled for a time.
