A small low is this afternoon spiralling in the Hauraki Gulf – sending out bursts of heavy downpours that are affecting upper North Island regions like Auckland and Waikato.
As of 2:45pm “torrential” downpours were being reported around Auckland.
WeatherWatch.co.nz says these heavy bursts of rain are localised but this afternoon will continue to pop up in more parts of the city. Some downpours may cause localised flash and surface flooding.
It’s a similar forecast for Waikato – mainly South Waikato with heavy showers and some thunderstorms this afternoon.
While there is a risk for thunder in Auckland today the thick cloud cover has so far prevented afternoon heating from taking hold. However thunderstorms have been detected in the city in the past 15 minutes and more are possible until early evening. “If the sun comes out that could also lead to a rapid escalation in thunderstorms and/or torrential downpours so people need to be aware that conditions could change quickly” says Mr Duncan,
“The good news is that this low is delivering a bit more rain than we thought it would – many farmers are telling us this rain couldn’t have turned up a better time”.
Some farmers in the north have reported drier conditions than this time last year.
WeatherWatch.co.nz says residents in Waikato and Auckland especially should be aware of severe weather risks this afternoon and watch for possible surface and flash flooding – along with the chance of isolated thunder and hail.
