Gisborne District Council - Cyclone Pam Update Saturday
Hi all, Pam still on track to start impact top of the coast late Sunday and will track down to the City early Monday
morning (see attached map). A warning will be issued shortly and it has 180 – 220mms in the ranges and 120mm elsewhere
with falls up to 30mm/hour, winds will be 120k initial from the south east. Haven’t got official wave heights yet but
they are significant.
The rain should only cause localized flooding problems and our main river systems should cope, although in recent events
I have seen the Uawa river reach its dangerous levels with these amounts. It is more than likely we will see power
disruption.
All the public preparedness given in other updates still apply.
GDC will be establishing an Emergency Operation Centre (EOC) in the CD office space today and will use the Council
Chambers for external media reps and briefings. The EOC will probably be fully activated around 0500hrs on Monday
morning.

SEVERE WEATHER WARNING.
ISSUED BY MetService AT 9:13am 14-Mar-2015 URGENT - IMMEDIATE BROADCAST IN: Bay Of Plenty Rotorua, Gisborne, Hawkes Bay
{MEDIA} SEVERE SOUTHEAST GALES AND HEAVY RAIN FOR NORTHEASTERN PARTS OF THE NORTH ISLAND LATE SUNDAY AND MUCH OF MONDAY
Severe Tropical Cyclone Pam, currently located near southern Vanuatu, is forecast to track southeastwards over the
weekend and pass east of New Zealand during Mondayand Tuesday. There remains some uncertainty as to how close to the
North Island the eventual cyclone track will be, however, it will likely be a significant event, with strong southeast
winds and rain expected over much of the North Island late Sunday and Monday, along with extremely large seas about the
east coast.
Around 200mm of rain is expected to accumulate in the ranges of Gisborne, northern Hawkes Bay and eastern Bay of Plenty,
with lesser but still significant amounts near the coast. Rivers and streams in these areas will rise rapidly and
localised surface flooding and slips are likely as well as hazardous driving conditions.
In addition, severe southeast gales are likely about Gisborne and Bay of Plenty for a time Monday, with gusts of 120
km/h in places but 160 km/h or possibly more about the eastern Bay of Plenty. Winds of this strength are likely to cause
damage to trees and powerlines and could lift roofs and make for hazardous driving conditions.
This is a developing situation and people are advised to stay up to date with the latest forecasts as further areas may
be added to this Warning.
