A category 4 (extreme) MHW is occurring near New Zealand, the strongest near-land MHW event on Earth at the moment 🔥

This is at least the 2nd time in the last 5 years that New Zealand has experienced an extreme MHW.

The 2017-18 MHW reached category 4 near the South Island. pic.twitter.com/pA5mH1yln1
