*Chart updated at 15:21 to include minor wording change. No other changes. A front brings heavy rain to the west and north of the South Island, with mostly a low risk of embedded thunderstorms, as depicted on the chart. However, the risk is considered moderate until late evening for Westland south of Hokitika and Fiordland north of Doubtful Sound, with heavy rain of 20 to 30 mm/h. Meanwhile, the same front moves onto Northland late in the day and the atmosphere there gradually becomes more unstable. The risk of thunderstorms is initially low in Northland but increases to moderate this evening, but there is also a moderate risk of localised downpours from afternoon with rain rates of 25 to 40 mm/h and possibly higher. Severe Thunderstorm Warnings will be issued for any downpours observed on RADAR. A low risk of thunderstorms spreads south into Auckland and northern Coromandel Peninsula this evening. There is minimal risk of thunderstorms or significant convection elsewhere in New Zealand today.
