If severe thunderstorms do occur, they can produce localised downpours with rainfall rates of 25 to 40 mm per hour.

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 be hazardous with surface flooding and poor visibility in heavy rain.

The message here is take care and be prepared. As always, forecasts can change quickly and without warning, so during this time please be on alert and check out our website for further information on preparedness and actions in severe weather: www.bopcivildefence.govt.nz/know-your-hazards/severe-weather/
