Heavy Rain Warning - Orange Area: Northland north of Whangarei Forecast: Expect 80 to 120 mm of rain. This rain comes in addition to the 60 to 80 mm of rain which has already accumulated in the east of Northland north of Whangarei. Peaks rates generally 10 to 20 mm/h but 25 to 40 mm/h possible in localised downpours, with thunderstorms also possible. Note that the largest accumulations are likely from about the Bay of Islands northwards. Impact: Streams and rivers may rise rapidly. Surface flooding, slips, and difficult driving conditions possible. Chance of upgrading to a Red Warning: Low. Impact: Action: Clear your drains and gutters to prepare for heavy rain. Avoid low-lying areas and drive cautiously.

Severe Thunderstorm Watch Area: Northland Forecast: A slow moving rainband is expected to lie over the north of Northland Wednesday night and Thursday morning. There is a moderate risk of thunderstorms embedded in the rainband, bringing heavy rain of 10 to 25 mm/h and small hail. There is also a moderate risk of Severe Thunderstorms producing localised downpours of 25 to 40 mm/h, especially in areas from the Bay of Islands northwards. 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. Impact: Note: A Severe Thunderstorm Watch means conditions are favourable for severe thunderstorms in and close to the watch area. People in these areas should be on the lookout for threatening weather conditions and monitor for possible Severe Thunderstorm Warnings.
