Met Office Chief Meteorologist Paul Gundersen, said “Exceptional, perhaps record-breaking temperatures are likely early next week, quite widely across the red warning area on Monday, and focussed a little more east and north on Tuesday.

“Currently there is a 50 per cent chance we could see temperatures top 40C and 80 per cent we will see a new maximum temperature reached.

“Nights are also likely to be exceptionally warm, especially in urban areas.

“This is likely to lead to widespread impacts on people and infrastructure.

“Therefore, it is important people plan for the heat and consider changing their routines.

“This level of heat can have adverse health effects.”

Weather experts predicted the extreme temperatures could result in population-wide adverse health effects, particularly for the most vulnerable.

Necessary changes to working practices and daily routines may be necessary, due to travel disruption including, road closures, delays and cancellations to rail and air travel services.
