Heat wave alerts in southwest England and the West Midlands have been raised from level two to level three, the same as in south-east England, as temperatures continue to rise.

Wednesday was the hottest day of the year so far, with recorded temperatures of 32.2 degrees Celsius (90 degrees Fahrenheit), and forecasters say there is hotter to come.
