What is a heat warning?

Ah, that’s what you call a “weather alert” in Australia.  “Heat warning” means that the weather is expected to be very hot, and heat-related illness is likely.  Some people also call it a “red-hot day” or a “scorcher”.

What is a heat related illness?
user
Most heat-related illness is not serious, but it can be dangerous.  The most common effects are heat exhaustion or heat stroke.  Heat exhaustion occurs when your body gets too hot, but you can’t get cool quickly enough to handle the heat.

That sounds pretty scary. It is good to know though.
