UPDATE: This advisory represents a DOWNGRADE from WARNING. The reason for this downgrade is because the magnitude of the earthquake has been revised down to M5.9

NATIONAL ADVISORY: TSUNAMI ACTIVITY – EXPECT STRONG AND UNUSUAL CURRENTS AND UNPREDICTABLE SURGES AT THE SHORE
We expect New Zealand coastal areas to experience strong and unusual currents and unpredictable surges at the shore following a magnitude 5.9 earthquake near 40 km north of Te Anau at 2026-07-16 09:14 PM.

Strong currents and surges can injure and drown people. There is a danger to swimmers, surfers, people fishing, and anyone in or near the water close to shore.

People in or near the sea in the following areas should move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.

AREAS UNDER THREAT:
The West Coast of the South Island from MILFORD SOUND to PUYSEGUR POINT.

ADVICE FOR PEOPLE IN AREAS UNDER THREAT:
STAY OFF THE BEACHES AND SHORE AREAS

People on boats, live-aboards and at marinas should leave their boats/vessels and move onto shore. Do not return to boats unless instructed by officials.

There is no need to evacuate other areas unless directly advised by local civil defence authorities. Coastal inundation (flooding of land areas near the shore) is not expected as a result of this event. We are advising people to:

Move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.

Do not go to the coast to watch the unusual wave activity as there may be dangerous and unpredictable surges.

Listen to local civil defence authorities and follow any instructions.

Share this information with family, neighbours and friends.

Strong and unusual currents and unpredictable surges will continue for several hours and the threat must be regarded as real until this Advisory is cancelled.

This National Advisory has been issued following an assessment of information available. The situation may change as new information becomes available. Listen to the radio or TV for updates, or check www.civildefence.govt.nz

The Severe Thunderstorm has moved inland and weakened, so the Warning is lifted.

SEVERE THUNDERSTORM WARNING
TOP PRIORITY FOR IMMEDIATE BROADCAST

Issued by MetService at 03:24 pm Wednesday 15 July 2026.
Valid until 04:15 pm Wednesday 15 July 2026.

This warning affects people in the following local government areas: GREY and WESTLAND.

At 03:15 pm, MetService weather radar detected severe thunderstorms near GREYMOUTH, OFFSHORE GREYMOUTH and RUNANGA.

These severe thunderstorms are moving towards the eastsoutheast, and are expected to lie near GREYMOUTH, LAKE BRUNNER and MOANA at 03:45 pm and near INCHBONNIE, LAKE BRUNNER and KOPARA at 04:15 pm.

These thunderstorms are expected to be accompanied by large hail, possible tornadoes and frequent lightning.

Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, and make driving conditions hazardous.

Tornadoes can blow out windows, lift roofs, break large branches off trees, generate dangerous flying debris and blow vehicles off the road.

Frequent lightning is dangerous to people and livestock, especially those exposed outdoors or on the water, and can cause power surges and damage to electrical equipment.

The National Emergency Management Agency advises that as storms approach you should:
- Take shelter, preferably indoors away from windows;
- Avoid sheltering under trees, if outside;
- Get back to land, if outdoors on the water;
- Move cars under cover or away from trees;
- Secure any loose objects around your property;
- Check that drains and gutters are clear;
- Be ready to slow down or stop, if driving.
During and after the storm, you should also:
- Beware of fallen trees and power lines;
- Avoid streams and drains as you may be swept away in flash flooding.

This warning is due to be updated or lifted by 04:15 pm Wednesday 15 July 2026.
