    Hotspot
    Across the North Island, rainfall during the past week was generally higher than several previous weeks, with many locations receiving 10-20 mm and isolated pockets of 30 mm or more.

    Across the North Island, slight soil moisture increases were observed during the past week as a front brought much needed rain to drought affected areas. However, soil moisture levels continue to be well below normal across the vast majority of the island. Across the South Island, soil moisture levels generally increased in the north and decreased in the south during the past week.

    Hotspot
    Nearly all of the North Island has reached official hotspot status, with only a few isolated areas that have not quite reached hotspot criteria. Current hotspots in the South Island now include Nelson and nearby parts of Tasman, much of Marlborough, along with northern Canterbury, Banks Peninsula, and parts of Ashburton and Selwyn districts.

    Across the North Island, the past week once again featured little if any rainfall for most locations. Soil moisture levels in the lower South Island have improved markedly from last week.

    A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

  • Hotspot Watch 19 December 2019

    Hotspot
    Across the North Island, moderate to large increases in soil moisture levels were observed in many locations due to substantial rainfall in the past week. Across the South Island, substantial rainfall contributed to moderate to large increases in soil moisture levels in the vast majority of the island.
  • Hotspot Watch 11 December 2019

    Hotspot
    Across the North Island, notable increases in soil moisture levels were observed in the southwest, from Taranaki south to Wellington.
  • Hotspot Watch 5 December 2019

    Hotspot
    Across the North Island, notable decreases in soil moisture levels were observed from Northland to Waikato, including the Coromandel Peninsula.
