She said the expected travel path of the front could result in rain warnings for Gisborne, Hawke’s Bay and Wairarapa on Saturday or Sunday.
“The southerly winds could also be quite gusty and will be strong in exposed places, especially around the eastern North Island.”
O’Connor said both Hastings and Napier had topped 28C on Wednesday due to north-westerly conditions, with 24C coming on Thursday still making the Bay the warmest place in the country.
But Friday would bring a dramatic southerly drop to 17C and single-digits overnight, with similar temperatures likely over the weekend as a front from north of Bay of Plenty then sweeps around the east coast.
O’Connor said north of Napier and Wairoa was likely to see sustained rain.
