Latest update

From latest advisory update:

Based on preliminary modelling and comparison with historical events, the interpretation of the Tsunami Experts Panel is that a marine threat (ie threat to beach and small boats) exists for the entire east coasts of the North & South Islands from Puysegur around to Cape Reinga and extending south to Ahipara. Some land threat also exists (ie wave heights between 1 and 3 metres) for the Chatham Islands and Banks Peninsula. Wave height refers to maximum water level relevant to the normal sea level at the beach. This does not take tides into account. (PEMO note - high tide of 1.5m will occur in Porirua Harbour at 10.43am) Based on historicalk events it is expected that the greatest wave heights will occur between 6 and 12 hours after the initial arrivals.

See previous post for arrival times.
