Slow-mo low making a show across the North Island (+Animation & Photos)

Updated 6:22pm — A very slow moving low pressure system currently lies over Great Barrier Island and northern Coromandel Peninsula and is drifting eastwards towards the Bay of Plenty marine area. By Wednesday night it will be around East Cape and by Thursday morning it will fall apart east of the North Island as a high rolls into NZ.

The low is pulling down sub-tropical winds but also merging with the colder southerly blowing up the rest of the nation.

Winds are converging over Auckland City producing isolated downpours – although as of 5:35pm no repeat of the thunderstorms the city had on Monday afternoon. “Yesterday the low was to the west of Auckland so the region and city had a warmer northerly flow. Today the low is out over Great Barrier Island meaning the city is now getting the cooler southerly flow” says WeatherWatch.co.nz head forecaster Philip Duncan. One thunderstorm occurred at 4pm in the city.

Meanwhile the eastern North Island is still caught up in the northerly flow, prompting more big downpours and thunderstorms moving into Hawke’s Bay from the north. Mostly inland.

#HappeningNow: Very heavy rain with embedded #thunderstorms for parts of #BayOfPlenty.

Drive with care and watch for localised flooding.https://t.co/Pm2OWgtJRf

4:20pm update – #Napier a burst of rain, possibly heavy, about to move in – then easing.

Rain possibly setting back in again overnight but not at the levels experienced yesterday. 30 – 60mm is the current estimate for the next 36 hours.https://t.co/eveWdQiaoB for more data pic.twitter.com/4YSNwtAxWO

#Auckland – Our 2nd #flood alert for today. A convergence zone (a narrow area of heavy downpours with possible isolated hail & thunder) is lined up over the city right now. Flooding risks in isolated pockets between now and 6pm. Drive with care.

Spot the #low!

Slow moving & producing isolated thunderstorms.

You can also see the winds converging over Auckland, (pushing up the rainclouds & making for downpours).

Plus, as winds slide down the east coast it generates storms inland.https://t.co/Pm2OWgtJRf #FreeService pic.twitter.com/mFoD3jzPpo

#2PM Update: Heavy downpours in #Auckland. Sunny spells breaking through which may increase the intensity of these isolated downpours. Thunder possible (not happening yet though).#Coromandel: Heavy rain continues as the centre of the low tracks nearby. Slips/Flooding possible. pic.twitter.com/zLHMPj1cXw

Heads up #HawkesBay – Downpours are developing inland to the north, with a chance of localised thunderstorms. It's slowly spreading southwards and also developing over the ranges further south. It's a different set up to yesterday – but worth monitoring.https://t.co/nVbQsHSOdf pic.twitter.com/4zEkkUhRxu

#HappeningNow – #CoromandelPeninsula – Watch out for #slips and #flooding as very heavy rain now sets in to some areas.

The rain is slow moving on the southern edge of the centre of the low, which is now over the top of Great Barrier Island.

Saw this from Albany, guessing this brought the hail and thunder… pic.twitter.com/3QAMFuUfFu

Reflecting on a tough day for Napier yesterday. Hope everyone is safe and drying out. Looks like a more gentle rain going to fall tonight @WeatherWatchNZ pic.twitter.com/HL1P4YIccg
