A woman has been killed by a falling tree branch in London's Kew Gardens, as gales and torrential rain continue to hit parts of the UK.
The woman, believed to be around 30 years old, died on Sunday afternoon after she was struck by a large tree branch.
Kew Gardens is closed to the public for the day "as a precaution" in light of the Met Office warning of severe weather for London, including winds of more than 50mph.
Torrential rain on Monday morning saw properties flooded in Somerset, train services disrupted between Exeter and Bristol and Chester and north Wales, and delays on the roads in Shropshire.
The severe weather is expected to spread further across Britain over the next 24 hours, with some regions bracing themselves for wind speeds of up to 70mph and rainfall of up to 100mm.
Heavy downpours, equivalent to almost a month's worth of rain, were due in parts of the South West, northern England and Scotland.
Flood warnings have been put in place for the South West, Midlands and North East and flood alerts issued for other areas of the country, including Wales, by the Environment Agency.
It urged people to check its website for flood warnings and warned people to be prepared for significant disruption on Monday and in to Tuesday.
Alison Baptiste, flood risk manager at the Environment Agency, said: "We are already seeing travel disruption due to the wet weather and could well see flooding across the country this week.
"We strongly urge people to sign up to flood warnings, keep a close eye on local weather forecasts and be prepared for the possibility of flooding.
"We also ask that people stay safe by staying away from swollen rivers and not attempting to drive through floodwater."
It is a stark change from earlier in the month, when parts of Britain basked in warm temperatures in the mid-20s, a welcome break from the rain and wind which dogged much of July and August.
Sky News meteorologist Chris England said: "The change is already occurring and we're in for a rather wet, cool and windy end to the month, after a generally fine, warm three weeks.
"Parts of the South had nearly an inch of rain on Sunday, after a very dry spell for much of the month, and it's fairly cold too, with temperatures in the rain only just getting into double figures.
"It'll stay wet over the next couple of days, with up to 40mm (1.5in) likely in many areas and more than that in some parts.
"That'll be more rain than many areas have had so far this month and could well lead to some local flooding.
"It'll stay windy too, especially in the East, and with gusts up to 60mph there's a risk to high-sided vehicles."
Sky News weather presenter Nazaneen Ghaffar added that 30-40mm of rain fell in parts of the South West and southern Wales in just six hours on Sunday evening and also warned of more "torrential" conditions.
Wind speeds in the area around the Royal Botanical Gardens in Kew, southwest London, are thought to have reached a peak of 30mph at 4pm on Sunday and were likely to be close to that at the time of the woman's death.
An air ambulance was sent and extensive efforts were made to revive the woman but she was pronounced dead at the scene.
Her death is not being treated as suspicious and it is not known whether the matter will be referred to the Health and Safety Executive .
When the worst of the weather is over it is forecast to remain cool and unsettled for the rest of the week.
