Lancashire has been warned to brace itself for thunderstorms tomorrow as soaring temperatures bring unsettled weather
In Preston, temperatures could rise above 30 degrees after an overnight low of 18 degrees.
The Met office said: “Isolated heavy, and possibly severe thunderstorms are expected to develop late Wednesday afternoon across parts of Northern England and Southern Scotland.
“Some torrential downpours are possible leading to localised surface water flooding, with hail and frequent lightning also possible hazards.
“The public should be aware that there is a chance of some very localised significant disruption.
“By Wednesday, a hot and increasingly humid airmass is expected to be in situ across much of the UK.
“This airmass looks conducive to isolated thunderstorm development during the afternoon and into the evening.”
Meanwhile, the North West Ambulance Service is urging the public to take extra care.
Advanced Paramedic Sam English said: “As much as the warm weather is a pleasant change it can create various problems, particularly for the chronically sick, elderly, babies and young children and those who are fasting for Ramadan. The biggest risk during these hot spells is dehydration which is often characterised by lethargy, cramps, dizziness or confusion.
“Simple advice surrounds staying in the shade and keeping cool wherever possible, wearing sunscreen and a hat as well as keeping hydrated by taking regular cool drinks. This might seem straightforward but this will help prevent the incidents we see every day during the hot weather.”
