A showery unstable airmass is expected to develop over the lower South Island this afternoon and evening. For southern Southland, and inland parts of Clutha and Dunedin, there is a moderate risk of severe thunderstorms with localised downpours of 25-40 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 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. For information on preparing for and keeping safe during a storm, see the Civil Defence Get Ready website
