Oficiálne varovania pred nepriaznivým počasím v blízkosti 35.28°J 174.09°V

A slow moving rainband is expected to lie over Northland today until Thursday morning. There is a moderate risk of thunderstorms embedded in the rainband, bringing localised heavy rain of 10 to 25 mm/h and small hail. There is also a moderate risk of Severe Thunderstorms producing downpours, especially in areas from the Bay of Islands northwards. These downpours could bring rain rates of 25 to 40 mm/h, and possibly more, to localised areas. Note, these downpours could occur with or without thunderstorms. Rainfall of this intensity can cause surface and/or flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys, and may also lead to slips. Driving conditions will also be hazardous with surface flooding and poor visibility in heavy rain.

Expect 100 to 150 mm of rain but possibly 150 to 250 mm in localised places, with the largest amounts likely about the eastern hills and north of the Bay of Islands. Peaks rates generally 15 to 25 mm/h but 40 to 50 mm/h possible in localised downpours, with thunderstorms also possible. Note: It's possible this warning could be extended until Thursday afternoon. Impact: Streams and rivers may rise rapidly. Surface flooding, slips, and difficult driving conditions possible. Chance of upgrading to a Red Warning: Low.
