Roughly 130 million people in the US are under threat from the weekend into next week from a long-running heat wave that has already broken records with dangerously high temperatures, forecasters said.

Oppressive heat and humidity could team up to spike temperatures above 38C in parts of the Pacific North-west, the Mid-Atlantic and the North-east, said Jacob Asherman, a meteorologist with the National Weather Service.
