Severe Weather Outlook

Issued : 2:18pm Saturday 26 May 2018, Valid from Monday 28 May 2018 to Thursday 31 May 2018

A strong southerly flow is expected to lie over the country on early Monday, but this is expected to ease later on Monday and during Tuesday as a high moves onto the country from the west. There is moderate confidence that southerly winds along the east coast from Banks Peninsula to Gisborne, including Cook Strait and the eastern Marlborough Sounds will require a warning on Monday. There is also likely to be some rain in eastern areas, with snow about the Kaikoura Ranges and the Central Plateau of the North Island. There is low confidence that heavy snow above 400 metres will require a snow warning in North Canterbury and about the Kaikoura Ranges on Monday. There is also a low confidence that a heavy rainfall warning will be needed for the ranges between Wairoa and Gisborne during Monday.

The high should remain over the country until at least Thursday.
