MetService has issued a Severe Weather warning for northern and eastern parts of the North Island, where heavy rain and south to southeast gales are expected from this evening (Sunday) through to Tuesday. MetService Meteorologist Fulong Lu commented, “Tropical Cyclone Pam is expected to remain a very deep system as it passes to the east of the country late Monday and Tuesday”. 

Apart from heavy rain and severe gales, Tropical Cyclone Pam is expected to bring very heavy swells to the North Island east coast from Northland to Hawke’s Bay, 4 to 6m near the coast, and 6 to 8m offshore. People considering venturing near or into the water, are advised to take extra precautions, especially when winds are onshore, and check the latest forecasts for expected dangerous conditions. 

The Chatham Islands are expected to see Pam pass overhead around midday Tuesday, bringing torrential rain, severe gales, unusually heavy swells and very large waves (even by Chatham Island standards) from Monday evening.
