As a low pressure system approaches from the Tasman Sea, MetService has issued a Severe Weather Warning for Northland, Gisborne and Hawke’s Bay. Auckland, Coromandel and Bay of Plenty are not expected to be quite so exposed and remain on Severe Weather Watch.

“This low brings strong clockwise winds and a band of heavy rain,” commented MetService Weather Ambassador, Bob McDavitt. “It is on track to sideswipe eastern Northland tonight and lie off to the northeast of Gisborne on Friday.  As the low passes, rain may cause rapidly rising rivers and streams in and around the warning areas.”

McDavitt added that the central pressure of a low is one measure of its depth.  “This low centre was estimated to be 1008 hectoPascals at the start of Thursday and is forecast to fall to 996 by Friday, indicating that it is indeed a deepening system.  Gales are likely about exposed coasts both as the low approaches and also as it moves away.”

People in the warning and watch regions should be aware of this incoming low, keep up to date with MetService weather forecasts and warnings and plan accordingly.  Latest updates and weather warnings are available on and its mobile version,
