10pm: MetService says that at 7pm this evening (Sunday), Tropical Cyclone Hola was reclassified as an extra-tropical low. It is expected to track southeast close to the upper North Island tomorrow (Monday).

It is important to note that reclassification does NOT mean the cyclone has weakened. In this case, Cyclone Hola still has considerable potential for severe weather despite being reclassified.

This reclassification reflects that the structure of the low has changed, with the most severe weather no longer concentrated about the low centre. In this case, severe weather is expected to affect much of the upper North Island on Monday, even though the low centre is expected to track over the water just to the northeast of the North Island.

Current predictions for Rotorua and Bay of Plenty:

Valid: 14 hours from 10am to midnight Monday

Forecast: Gale southeasterlies developing Monday morning, then turning gale southwesterlies late Monday afternoon or early evening, with severe gales gusting 120 to 130 km/h in exposed places. Winds easing overnight Monday.

What you can do today:

  • Store outdoor furniture inside or stack it up in a sheltered corner;
  • Secure your trampoline;
  • Do a quick check of your property and pick up any objects that could be picked up by the wind.

"New Zealand has enjoyed a settled and generally sunny weekend, which is quite literally the 'calm before the storm'," said MetService Meteorologist April Clark says.

Tropical Cyclone Hola was a Category 2 system at 7am this morning, and was located approximately 10 degrees of latitude north of Cape Reinga. During today, the system is expected to track south and eventually be reclassified as Cyclone Hola (rather that Tropical Cyclone Hola). This reclassification reflects that the structure of the low will change, with the most severe weather no longer concentrated about the low centre.

"However, don't be fooled by the reclassification, as impacts for some regions of the country are forecast to be significant" Clark warned.

Current models are predicting Cyclone Hola to swiftly skirt the northeast of the North Island during Monday, bringing Severe Weather to eastern parts of the upper North Island. Severe Weather Watches and Warnings have now been issued for Monday, with rain accumulations of as much as 150mm and wind gusts of up to 130km/h forecast for eastern regions from Northland to northern Hawkes Bay.

Heavy rain could cause temporary flooding, and rivers to rise rapidly,while strong winds have the potential to cause damage to powerlines and unsecured items. Heavy swell is also expected over the eastern coastline from Northland through to Gisborne on Monday. Strong onshore winds will also add to the wave heights for Coromandel Peninsula and Gisborne.

"This system is compact but fast moving, meaning that those expected to be impacted should expect weather conditions to change rapidly, so keeping  updated with the forecast, Civil Defence and New Zealand Transport Agency  is key," Clark explained.

There is still uncertainty about how Tropical Cyclone Hola will track and what effect it will have on New Zealand but this weekend is a good time to check you are prepared in case there is a severe local impact.

Based on current tracking there is forecast to be a high risk of heavy rain and severe gales in the Bay of Plenty from early Monday through to Tuesday.

Rotorua Civil Defence staff remain on standby and continue to monitor the situation and our Primary Civil Defence Emergency Controller Stavros Michael is encouraging locals to take the time this weekend to make some basic checks around the home.

“Council continuously monitors developing weather patterns. These have changed in the past year as Rotorua has experienced more severe events such as thunderstorms and heavy rain,” he says.  

When severe weather is expected for the district, council staff remain on standby and activate preparedness measures including monitoring inflows to the Wastewater Treatment Plant and notifying contractors about the approaching weather.

“At present we are keeping a watchful eye on the progression and movements of Hola,” Mr Michael says.

“Like any severe weather event which may possibly descend on Rotorua, we encourage residents to prepare just in case.”
