The Met Office has issued an amber 'Extreme Heat weather warning for parts of Cornwall and says there is a 90% probability of heatwave conditions, as it
It will be in place for areas north of Bodmin between midnight on Thursday 11th August and 11.59pm on Sunday 14th August, with some places expected to see highs of over 30C.
The warning is alongside an amber 'Heat Health Alert' for the whole of England, including the Duchy, that has now been extended to last until Sunday night.
The UK Health Security Agency has also issued an alert which will remain in force until 6pm on Saturday 13th August.
Meteorologist Tom Morgan told us: "It's worth noting that this will be a step down. We're not anticipating the temperatures to be quite as high in general but it is a prolonged period of hot weather so it will be more impactful to the more vulnerable people".
He added: "If you don't like the heat, I suggest trying to head to the coast. Otherwise we could see some close to record-breaking temperatures for Cornwall. The August record for Cornwall is 32.4C and we could certainly come close to that on Friday and Saturday this week".
The amber 'Extreme Heat' weather warning covers most of England and states: "A hot spell will develop across parts of England and Wales later this week.
What can we expect?
Adverse health effects are likely to be experienced by those vulnerable to extreme heat.
The wider population are likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat related illnesses.
Some changes in working practices and daily routines likely to be required.
An increased chance that some heat-sensitive systems and equipment may fail.
More people are likely to visit coastal areas, lakes, rivers and other beauty spots leading to an increased risk of water safety and fire-related incidents.
Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays.
"Temperatures will increase across much of the UK over the coming week. Temperatures will be highest across parts of England and Wales with these peaking on Friday and Saturday. In addition to high daytime maxima, temperatures overnight will remain very warm, especially in larger urban areas".
The Met Office 'Heat Health Alert states: "There is a 90 % probability of Heat-Health Alert criteria being met between 1200 on Tuesday 09 Aug and 2100 on Sunday 14 Aug in parts of England.
"High pressure dominating this week, with fine and dry conditions across most of the country, prolonged sunshine, and light to moderate breezes. Temperatures rising from warm or very warm to locally hot in most regions, with a focus of the warmest weather in central-southern England.
"Headline max temperatures reaching mid 30s, most likely Friday or Saturday.
"The biggest uncertainty is over the end of the hot spell, with thundery showers expected to arrive from the south through the weekend introducing cloudier, somewhat cooler conditions.
"Confidence in the details of these showers remains low however with potentially for a continuation of warm or very warm temperatures into next week for some areas before we see a gradual return to around average".
