The onset of cold weather leads to an almost immediate increase in weather-related deaths which can remain raised for up to four weeks after. Deaths from cardiovascular conditions peak first, followed by stroke and then respiratory conditions. Negative health effects start at relatively moderate outdoor mean temperatures of 4 to 8°C. Flooding and health For the first time, a high resolution model that captures the detail of convective, or extreme, rainfall events has provided 100 years of data, spanning the past, present and future continuously, to analyse the future risk of rainfall with the intensity that can cause flash flooding. Both cold weather and flooding are linked to respiratory disease from mould and damp. What’s the impact of our changing climate?

At 27ºC or over, people with impaired sweating mechanisms find it especially difficult to keep their bodies cool (for instance the very young, people with long term health conditions or older people, particularly people taking certain medications). Northern Ireland and parts of Scotland could reach as low as -3C (26.6F). The south of England and Wales could see about two inches of rain on Thursday and Friday, and the Met Office is warning of possible thunderstorms, flooding and travel delays.

If the arrow points towards land, most of the waves’ power will reach Here at UKHSA, we play a key role in providing evidence and advice to help policy makers, organisations and individuals do just that. The risks to our health from adverse weather In terms of flooding, the third UK Climate Change Risk Assessment in 2021 identified flooding as one of the most important climate change adaptation challenges facing the UK. In all future climate change scenarios, direct and indirect flood risks are projected to rise over the course of the 21st century. An example of an intense rainfall event with 20mm/hr is London in July 2021, when 40mm of rain fell over three hours at Kew Gardens, flooding the underground and other infrastructure.

No risk of UV - It’s safe to stay outside. 1-2 Low - You can safely stay outside. Consider sunscreen in direct sunlight. 3-5 Moderate - Take care during midday hours and do not spend too much time in the sun unprotected. Sunscreen advised. 6-7 High - Seek shade during midday hours, cover up and wear sunscreen. 8-10 Very high - Spend time in the shade between 11am and 3pm. Shirt, sunscreen and hat are essential. 11 Extreme - Avoid being outside during midday hours. Shirt, sunscreen and hat essential. During periods of hot weather last year – the hottest on record – we saw thousands of heat-related deaths, each one a human tragedy, also leading to significant pressure on our health and care services. The dangers of cold weather There will be an increasing tendency towards cooler conditions, however in the southern parts of England and Wales we’ve got the prospect of heavy rain coming in. We’re saying there is a significant rain warning from 9pm on Thursday through to midnight on Friday, and we can expect 20 to 30mm in some places in a couple of hours. Even up to 50, 60 or possibly up to 70mm across the high ground of Wales.”Their personal LinkedIn profile, as well as social media accounts associated with the business on platforms like Facebook.

An important role for UKHSA is to monitor the health effects of adverse weather, and our changing climate more generally, and provide advice and guidance on how we can adapt to meet these challenges head on. The arrow shows the direction the wind is blowing. The letters show the direction the wind is blowing We know that climate change is making these problems worse, increasing the number of adverse weather events, with these events becoming more frequent and intense in the years ahead.Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as This is like starting 12 weather forecasts and running them for 100 years, except the researchers are not interested in the weather on a given day but rather how the occurrence of local weather extremes varies year-by-year. By starting the model runs in the past it is also possible to verify the output against observations to assess the model performance. At this level of detail, it is possible to more accurately assess how convective downpours that can lead to flash flooding will change, for example when the intensity of the rain exceeds 20mm/hour. Thresholds of rainfall intensity like 20mm/hr are used for aspects of planning such as surface water drainage and flood risk.
