Severe Thunderstorm watch

Issued by MetService at 12:33 pm Sunday 12 March 2017

Valid until 03:00 pm Sunday 12 March 2017

A slow moving rainband over Auckland has brought areas of heavy rain this morning. This rain is likely to bring further heavy rain with downpours of 25 to 50mm/hr (and possibly more) in localised areas until about 2pm. Rainfall of this intensity can cause 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.

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.
