Severe Thunderstorm Watch Area: Auckland,Great Barrier Island Forecast: An unstable northwest airflow lies over the northern North Island. There is a moderate risk of thunderstorms about Auckland, including Great Barrier Island, from mid-evening until early tomorrow morning. Whether these thunderstorms occur or not, there is a chance of localised downpours of 25 to 40 mm per hour. Areas about and near the Hauraki Gulf are most likely to experience the downpours, but they may also occur elsewhere in Auckland. 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.
