Video / NZ HeraldAn already drenched East Coast is preparing for hours of torrential rain which might see parts of the region become isolated again. Tairāwhiti has been put under a 12-hour heavy rain watch and an orange heavy rain warning by MetService as a subtropical low heads East. It doesn’t heal overnight and doesn’t get fixed overnight so it’s going to be a long drawn-out process with more heavy rain forecast tomorrow and then on and on. We have issued a heavy rain warning for the region for tomorrow. Strong winds and heavy rain are expected to affect Vanuatu and northern parts of New Caledonia late Wednesday and during Thursday.”
