In Romford, 82-year-old June Simmonds became trapped on the first floor of her house as the flood water rose. 

Later, when it subsided, her daughter Kim Cook had a look at the damage.        

She told the BBC the house was "absolutely full" and "swimming".

"I just want to cry, because it's just gonna take so much again to get it back to where it was," she said. 

"There's a really long road ahead. This is the second time and it was as bad last time and I just feel really sorry for my mum."

Milly English, from Battersea, south London, tells us about her night of drama.

“I woke up to people knocking and banging on my door around 3am. At first I thought it was a brawl outside so I just ignored it, but it was persistent so I looked out the window and was shocked at what I was seeing," she says.

"A guy was thigh-deep in the water going from door-to-door to make sure people were OK. My roommates and I saw that the flooding had entered our house, so we used a broom to push it back into the street. My mum has lived in the same area for over 30 years and said she has never seen anything like it,” she adds.

Much of the UK has recently been hit by thunderstorms, but what is the best way to stay safe when thunder and lightning hits? 

If a storm is approaching, take cover inside or in a car with the windows wound up - sheds, isolated trees and convertibles do not afford sufficient protection. Boaters and swimmers should get to shore as quickly as possible, as water conducts electricity. Read more on what to do here.
