MetService has issued an Orange Warning for both rain and thunderstorms through to midday Friday.
“The weather event coming up from the south is a convective system, which could deliver heavy downpours anywhere across the Coromandel without warning.”
Rainfall amounts could reach 120mm or more over this time, MetService said.
Strong north to north east winds will continue throughout the warning period which is likely to result in wave overtopping along the Thames Coast Road, especially during the high tide periods: 9pm tonight (Thursday) and Friday morning at 9.45am, MetService said.
“Our Civil Defence team urges everyone to keep safe, clear gutters and drains, avoid any unnecessary travel, check and report any changes to slip areas that occurred during last year’s storms.”
Metservice said, above all, stay informed and up to date on the weather as this event is unpredictable.
“We will provide further updates as they come to hand.”
