ISSUED BY METSERVICE 28-Dec-2011

HEAVY RAIN ON THE WAY FOR PARTS OF NORTHERN AND CENTRAL NEW ZEALAND

A low of tropical origins over the north Tasman Sea is expected move
very slowly towards the North Island during the next few days, before
weakening and crossing northern New Zealand late Sunday or early
Monday. The low is forecast to direct a warm, humid north to
northeast flow over northern and central New Zealand, bringing rain
to many areas. The heaviest falls are expected about the Nelson
Region, northern Marlborough, Taranaki and also Northland which has
been added to the latest Severe Weather Warning. 

Some heavy rain is also likely about Buller, Coromandel Peninsula,
parts of Waikato, and the central North Island high country from late
Thursday through to Saturday. Rainfall accumulations here are likely
to come close to warning criteria and a Watch will be maintained.

Heavy rain is also expected to spread into Bay of Plenty and
Wellington overnight Thursday or Friday morning and continue into
Saturday or possibly Sunday in Bay of Plenty. These areas are
considered more likely to receive significant rainfalls and therefore
may well be upgraded to a full warning nearer the event.

SEVERE WEATHER WATCH FOR CANTERBURY,WAIKATO,BAY OF PLENTY ROTORUA
ISSUED BY METSERVICE AT 1054hrs 16-Dec-2011

SIGNIFICANT RAIN POSSIBLE ABOUT MID CANTERBURY TODAY, INCLUDING BANKS
PENINSULA AND PARTS OF CHRISTCHURCH. WATCH UPDATED TO ADD POSSIBLE
HEAVY, THUNDERY FALLS FOR WAIKATO AND WESTERN BAY OF PLENTY ON
SATURDAY

A prolonged period of moderate rain is likely about parts of Mid
Canterbury through to this evening, especially about Banks Peninsula
and higher areas of Christchurch. Rainfall totals are not expected
to reach warning criteria, but lesser amounts, such as 30 to 50mm are
possible through to 8pm today. These lower totals have the potential
to cause localised surface flooding, especially in the damaged parts
of Christchurch and a Watch will be maintained.

This Watch is extended to add the possibility of some heavy downpours
about Waikato and western Bay of Plenty during Saturday, especially
in the afternoon and evening. There is a risk of rainfall amounts
reaching short duration warning criteria (for example 50 to 70mm in a
6 to 8 hour period) over parts of Waikato and western Bay of Plenty
during Saturday. Localised rainfall rates could reach 25 to 35mm per
hour in thunderstorms during the afternoon, which would add to the
risk of surface flooding and possible flash flooding and make for
hazardous driving conditions (see the latest Severe Thunderstorms
Outlook on metservice.com for more details).

MetService forecasters will continue to monitor the situation and
people in Waikato and western Bay of Plenty are advised to remain up
to date with the latest forecasts in case a full warning becomes
necessary.
