MetService has updated its Severe Weather Warnings to cover further heavy rain on Tuesday for Gisborne and Hawke’s Bay, and severe southeast gales winds from Bay of Plenty to the Kapiti Coast.

“These warnings are the result of a strong southeast flow lying sandwiched between a slow moving low close to Auckland and a large intense high over the South Island” commented MetService Weather Ambassador, Bob McDavitt. “Strong winds from the southeast are rare, and gusts of around 120 km/hr are strong enough to damage trees and powerlines, especially about the central North Island forests.”

According to MetService this vigorous flow should ease by late Wednesday but is likely to remain in place over the North Island for the remainder of the week.  “By way of contrast, the high pressure system over much of the South Island should bring sunny days and areas of light wind until Saturday, just right for the remainder of the school holidays.”

McDavitt added that another low is likely to move towards the country from the tropics this weekend.  “The track of this system is uncertain at this stage.  People making travel plans for the end of the school holidays are advised to take into account weather updates in the media or on the web at metservice.com, or, for mobiles, at m.metservice.com.”
