A Warm Spring Week

November 22, 2015

Another busy spring week lies ahead after a weekend which saw one of the most spectacular thunderstorm events of recent years over the upper North Island. Lightning detectors recorded over 10,000 strikes for the event, peaking at over 3,500 strikes in a two hour period on Saturday morning, while Whangaparaoa gusted to 106km/h and parts of the Coromandel received over 60mm of rain in 2 hours.

“Looking to the week ahead, it’s a fine start for the northern half of the country, as a ridge moves over,” said Meteorologist Rob Kerr. “The east of the South Island is also looking dry, with temperatures there likely to reach the mid-twenties for most days this week. However, a Severe Weather Warning and Watch is in place for western parts of the South Island, as the moist northwesterlies south of the ridge are set to bring significant amounts of rain there on Monday and Tuesday,” he added.

“The ridge over the North Island gradually slides away to the east on Wednesday, and a warm front follows in its wake bringing rain to many parts of New Zealand,” he said. “Northwest winds over central and southern parts could potentially become severe on Thursday, and further heavy rain is expected in western parts, ahead of a cold front moving in from the southwest on Friday,” Kerr Cautioned.
