MetService NZ says skies may be blue over most of Aotearoa on Monday, but there is a Severe Thunderstorm Watch in place for the ranges of Gisborne and northern Hawke's Bay from 2pm to 9pm.
"In the event of a thunderstorm, there is a risk of localised downpours of 25-40mm per hour, which may lead to surface flooding or slips," MetServicen says.
"On Sunday, a thunderstorm moved over Gisborne city at 5pm which produced a downpour of 29mm within an hour; however, today the thunderstorm activity is most likely confined to the mountain ranges."
