Severe thunderstorm watch for Bay of Plenty
MetService has issued a severe thunderstorm watch for the Bay of Plenty, Waikato, Coromandel Peninsula, Great Barrier Island, Auckland and Northland regions.
A very warm and moist air mass covers the northern parts of the North Island today.
“There is a moderate risk of thunderstorms for Waikato, far western Bay of Plenty including Tauranga, Auckland, Coromandel Peninsula and Northland from late morning onwards,” says MetService’s Mark Todd.
“These thunderstorms are expected to be slow moving, and consequently there is a moderate risk of severe thunderstorms producing localised downpours of 25-40mm per hour, or possibly even torrential rain of greater than 40mm 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 very heavy rain.
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.
This watch will be updated by 1pm Sunday December 12.
