Giant storm vortex grows above Auckland

The ominous tentacles of a giant thunderstorm have spread out in the sky above Auckland.

The video was shot by Newshub cameraman Billy Paine outside the MediaWorks office on Tuesday.

The timelapse shows a giant vortex sucking dark clouds into its clasp as it prepared to unleash another burst of lightning and hail on the city.

It comes after the Ministry of Civil Defence and Emergency Management issued a warning that as the storms approach, people need to:

  • Take shelter, preferably indoors away from windows
  • Avoid sheltering under trees, if outside
  • Move cars under cover or away from trees
  • Secure any loose objects around your property
  • Avoid streams and drains as you may be swept away in flash flooding

MetService has issued a severe thunderstorm warning for the Auckland region.

"These thunderstorms are expected to be accompanied by very heavy rain and large hail," a spokesperson says.

"Very heavy rain can cause surface and/or flash flooding about streams, gullies and urban areas, and make driving conditions extremely hazardous.

"Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, and make driving conditions hazardous."
