A Hawke’s Bay Regional Council weather station, Te Koau, located in the Ruahine Ranges, unofficially measured 70mm of rainfall on Saturday.
Meanwhile, a MetService weather station in Hastings measured rainfall of almost 24mm on Saturday, which made it the wettest day over the past month at that station.
By Sunday mid-afternoon, the same weather station had measured a further 17mm of rain.
Monday is forecast to experience even heavier rainfall at that weather station than what fell over the weekend.
Hawke’s Bay Civil Defence Emergency Management Group encouraged the public to keep up to date with the latest forecasts, in case the MetService weather watch was upgraded.
“There is still uncertainty with the distribution and intensity of the heaviest rain,” a post from HBCDEM read.
“Please keep up to date with the latest forecasts in case this watch is upgraded to a warning or new areas are added.”

Despite the rainfall, all state highways were open as of Sunday afternoon across Hawke’s Bay, according to Waka Kotahi NZ Transport Agency.
HBRC Works Group had staff monitoring the Heretaunga Plains drainage systems over the weekend.
