so even in a part of the usa accustomed to extreme heat and heat waves, this is a particularly difficult and indeed extraordinary situation. death valley, california on friday recorded a high of 54.1; celsius, 130 fahrenheit, matching a temperature recorded in august last year which some argue is the highest temperature reliably recorded on earth, but the official record at death valley actually goes back to 1913 at 56.7 degrees celsius. now, whilst not expected to threaten that this weekend, we still see temperatures getting a little bit higher over the weekend in death valley. gradually, temperatures will subside as we go through the week, head closer to the seasonal average. may also threaten a record at las vegas. regardless of the actual numbers, regardless of records, this is clearly another extreme and dangerous heatwave affecting some people and places in the usa. thanks to nick for that update.
