90%
In the first third of the year, Auckland had already recorded 90% of its annual normal rainfall, taking the Auckland Anniversary floods and the severe weather event caused by Cyclone Gabrielle into account.
49.5mm
In one hour, the Ōrewa gauge recorded 49.5mm of rain – the heaviest hourly downpour on Tuesday morning, MetService meteorologist Andrew James said.
6mm
For context, anything over 6mm of rainfall in one hour is considered heavy.
91.5mm
By about 2pm on Tuesday, the Te Pai Park weather station (in Auckland’s Henderson) had recorded 91.5mm of rain, James said.
Most of this fell in the three-hour period between 9am and noon, he said.

115mm
To put that figure into context, the average monthly rainfall for May at the Auckland Airport site is about 115mm, James said – so not far off a month’s worth of rain had fallen at one site in one day.
The Whenuapai Airport station saw 78.8mm in the 12 hours to 1pm, and 81.5mm was recorded in West Harbour.
“Plenty” of areas in Auckland saw 50, 60, or 70mm of rain on Tuesday, he said.
300
More than 300 weather-related calls were made to Fire and Emergency for help between 8am and 6.30pm.
More than half of these calls came through between 12 and 1pm, on-call commander Brad Mosby said.
