Overnight tonight and during tomorrow the squeeze will be on with isobars starting to get closer together due to an incoming front in the Tasman Sea and an anticyclone to the north of the country.

The main affect of this squeeze will be felt about the Marlborough Sounds, Cook Strait and the lower North Island. Gale northwesterly winds are possible in these areas from midday tomorrow says WeatherWatch.co.nz

Northwesterlies will be breezy to strong at times from North Canterbury through to Blenheim tomorrow afternoon however gale winds are unlikely. From evening the strong northwesterlies about the lower North Island spread into Hawkes Bay and later after midnight down most of the West Coast of the North Island. Coastal Fiordland will experience strong to gale southwesterlies after midnight also.

Rain is likely on the West Coast of the South Island tomorrow and overnight will spread onto western regions in the North Island. Southland and southern parts of Otago will likely experience a few falls from evening.
