Today has been the hottest day of the year so far in the UK, the Met Office has said.
A high of 30C (86F) was recorded in Chertsey, Surrey.
It’s the highest recorded in the UK since 10 September last year, the weather agency said.
Winterbourne in Gloucestershire had 28.7C, Pershore in Worcestershire 28C, and Usk in Monmouthshire 27C.
It could get even hotter on Wednesday and some areas could see 31C (87.8F), the Met Office added.
A yellow alert from the UK Health Security Agency (UKHSA) is in place for most of England until 5pm on Thursday.
It warns there could be “significant impacts” in the health and social care sector and an increase in mortality in over-65s and people with health conditions.
