MetService has issued heavy rain watches in Gisborne, Hawke’s Bay, Bay of Plenty, and Wairarapa for the start of the work week.

Heavy rain warnings are in place for Gisborne from Tolaga Bay onwards, and the inland ranges of Hawke’s Bay including the Ruahine Range.

MetService says the affected areas can expect 120mm to 150mm of rain, peaking at a rate of 15mm/h in Gisborne and 20mm/h in the Hawke’s Bay ranges.

Heavy rainfall may cause streams and rivers to rise rapidly, possibly causing surface flooding, while driving conditions may be hazardous.

Periods of heavy rainfall are forecast for Gisborne (south of Tolaga Bay) and Wairarapa (from Carterton northwards).

Those in the Tararua District and Wairarapa should see the weather ease by Monday night.
