A WEEK OF TWO LOWS

May 2, 2011

A deep low over the central Tasman Sea is bringing rain to many places in the North Island and the north and west of the South Island.  MetService has a Severe Weather Warning and a Severe Weather Watch for heavy rainfall in places from Northland through to Gisborne and for northwest Nelson.

“Rain is starting to ease in Northland,” commented MetService Weather Ambassador, Bob McDavitt. “People in Coromandel and northwest Nelson should experience their heaviest rain through until Tuesday morning,and for northern Gisborne the peak should be over by Tuesday night,”

McDavitt added that many of these areas are still wet from last week’s rain. “Slips and surface flooding are more likely than normal, producing hazardous driving conditions.  But Hawke’s Bay isn’t in the firing line this time.

“As soon as the current low departs the New Zealand area, which is expected to happen about mid-week, another low is expected to turn up. This is likely to be quite different from the current one – it will come from the west, and should eventually bring a change to cooler westerly winds with squally showers.”

People travelling around the country are advised to check the latest weather forecasts, watches and warnings on the web at metservice.com, or for mobiles at m.metservice.com.
