New Zealand: Severe weather forecast across northeastern regions through at least June 26

Severe weather is forecast across northeastern North Island through at least June 26. A low-pressure system is forecast to approach the northeast of the North Island June 25 before tracking eastwards June 26, bringing heavy rain to Hawke's Bay and Gisborne, especially from SH5 to Tolaga Bay, along with severe southerly gales around northern Hawke's Bay and Gisborne. As of early June 24, the New Zealand National Meteorological Service (MetService) has issued the following weather warnings:

• Orange Heavy Rain Warning (middle level on a three-tier scale): Gisborne/Tairawhiti about and south of Tolaga Bay and Hawke's Bay north of SH5. Rainfall of 15-18 cm (6-7 inches) is forecast inland and 8-12 cm (3-5 inches) about the coast. Further rainfall is possible late June 26-the afternoon of June 27.

• Orange Strong Wind Warning: Gisborne/Tairawhiti and Hawke's Bay from Wairoa northwards, including Mahia Peninsula.

• Yellow Heavy Rain Watch: Gisborne/Tairawhiti north of Tolaga Bay and south of Ruatoria, and Hawke's Bay about and south of SH5.

• Yellow Strong Wind Watch: Bay of Plenty east of Opotiki.

Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rain has saturated the soil.

Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are likely where significant flooding or landslides impact utility networks.

Floodwaters and debris flows will likely render some bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces will probably cause hazardous driving conditions on regional highways. Authorities will likely temporarily close some low-lying routes that become inundated by floodwaters. Flight delays and cancellations at airports are probable.

Localized business disruptions are likely in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
