Strong Wind Watch
Cyclone Vaianu is likely to move across the North Island on Sunday, 12 April. If it does, it will bring damaging, potentially life-threatening winds. However, uncertainty remains in the cyclone's exact track, so the locations of the most severe winds are not yet certain. As confidence in the track increases, parts of this Watch will be upgraded to Orange or possibly Red Warnings. Vaianu will also bring heavy rain, with Heavy Rain Watches and/or Warnings likely to be issued on Thursday for some areas. Impact: Damage to trees, powerlines, and unsecured structures possible. Driving may be difficult, especially for high-sided vehicles and motorcycles. Chance of upgrading to a Warning: High.
Action: Prepare your property by securing items that can be picked up by strong winds. Drive cautiously.
