Heat warning issued across Yorkshire by the Met Office as temperatures set to exceed 30C
A heat warning has been issued across Yorkshire by the Met Office - as temperatures are set to soar between Wednesday and Friday.
The current 'heat-health' watch level has been immediately raised to level 2.
The warning is triggered as soon as the risk is 60% or above for threshold temperatures being reached in one or more regions across the UK on at least two consecutive days and the intervening night.
The Met Office said: "This is an important stage for social and healthcare services who will be working to ensure readiness and swift action to reduce harm from a potential heatwave.
"There is a 80% probability of Heat-Health criteria being met between 0900 on Wednesday and 2100 on Friday.
"Temperatures are expected to climb significantly this week, with good confidence for a period of hot weather between Wednesday and Friday.
"Temperatures exceeding 30 Celsius are expected quite widely, especially in central, southern and east England, although most coasts will be less hot.
"Fine, sunny conditions on Wednesday, just the chance of isolated thunderstorms in the far north.
"Thursday similar, but a greater risk of thunderstorms breaking out in parts of the north and west later.
"Friday may see a more general risk of thunderstorms across England.
"A transition back to fresher, more changeable weather currently looks likely over next weekend, although there is uncertainty in the detail at present."
An update will be issued when the alert level changes in any region.
Alerts are issued once a day by 9am if required and are not subject to amendment in between standard issue times.
