Given all the warnings and rain occurring you would expect an amazing satellite image. BUT it looks like a small feature. Quite strange really.

David · Unread post by **David** » Tue 04/04/2017 19:27

Already up to 64mm here, looking likely my record for highest daily rain will be broken (73.6mm on 23 Jan 2011).

Latest weather warning has an additional 120-180 mm possible across Auckland next 26 hrs, rare to see a rain warning that substantial here.

I was thinking the same but but more for the fact it's right across the North Island. Unprecedented rainfall levels across such a broad area.

LandSAR activated in Kohimarama. Significant Landslide into buildings

Just hit 100mm here since 4am this morn.

Had to move the neighbour's car earlier, as last month's slip just below it has slipped some more…

By text-message just received from Auckland Civil Defence:

"Significant weather now impacting the Auckland Region. There is real concern for rapid and extreme rainfall accumulations and associated localised flooding in the next few hours, while these downpours are slow-moving."

busy warning map!

I see there is a 4 -5C temperature difference between Whangaparoa and Manakua city.

jamie · Unread post by **jamie** » Wed 05/04/2017 06:04

Certainly a wet night. A bit of a reprieve now before the next onslaught of rain.

Manukau heads obs · Wed 05/04/2017 06:17

temperature back up to 20c now after that warm front (was 15c)
62mm here we got

NZstorm · Unread post by **NZstorm** » Wed 05/04/2017 06:20

Many parts of Auckland got 100mm overnight. 82mm here.

I will chase any thunderstorm development today but I expect storms to move fast. Some supercell potential given deep layer shear.

Bay of Plenty will get a big rainfall hit today.

jamie · Unread post by **jamie** » Wed 05/04/2017 06:20

Light beginning to show a flood on par with 2004. That was our worst ever. With the rain to come today I think I can safely say we will experience our worst flood on this farm in the 30 years we have been here.

NZstorm · Unread post by **NZstorm** » Wed 05/04/2017 06:23

Dewpoint back to 21C.

Manukau heads obs · Wed 05/04/2017 06:32
