The UK is set for its fourth heatwave this week - and it may not be the last of the summer.

英国本周将迎来今年第四次热浪——而且这可能还不是今夏的最后一波。

Temperatures are expected to climb again this week after a brief reprieve over the weekend.

在经历了周末的短暂缓解之后，本周气温预计将再次攀升。

Parts of southern England will yet again meet their heatwave criteria on Wednesday, which could reach highs of 32C or 33C, and more will on Thursday.

英格兰南部部分地区的最高气温可能在周三达到32或33摄氏度，届时将再次达到热浪标准，而满足标准的地区在周四会更多。

A yellow heat alert has been issued from 9am on Tuesday to 9am on Friday for the East and West Midlands, the southeast, southwest and east of England, as well as Yorkshire and the Humber.

英格兰东西米德兰兹、东南部、西南部和东部，以及约克郡和亨伯地区，已从周二上午9点至周五上午9点发布黄色高温预警。

But forecasters are expecting this week's hot spell to be a "north-south split", with clouds and outbreaks of rain continuing in Northern Ireland, Scotland and northern England.

但预报员预计，本周的高温天气将呈现“南北分化”格局，北爱尔兰、苏格兰和英格兰北部将继续有云层和阵雨天气。

The UK Health Security Agency has issued a warning of possible "significant impacts" on health and social care services, including a rise in deaths among the elderly or people with health conditions, and an increase in drownings.

英国卫生安全局已发出警告，称健康和社保服务可能面临“重大影响”，包括老年人和有基础疾病人群的死亡人数上升，以及溺水事件增加。

Emergency services are also braced for further wildfires.

应急服务部门也已为可能出现的更多野火做好了准备。

"With the Met Office warning that a fourth heatwave could develop this week, bringing another period of very hot weather to parts of the UK, fire and rescue services remain on alert and are continuing to prepare for renewed wildfire risk," a National Fire Chiefs Council spokesperson said.

英国国家消防局长理事会的一位发言人表示：“鉴于英国气象局警告称本周可能形成第四波热浪，给英国部分地区带来又一轮酷热天气，消防救援部门保持高度警惕，并继续为再度出现的野火风险做准备。”

"Most wildfires are preventable and we are asking everyone to play their part in helping to protect our communities, wildlife and natural spaces, while easing the pressure on firefighters who have already faced an exceptionally challenging summer."

“大多数野火是可以预防的。我们呼吁每个人都尽自己的一份力，帮助保护我们的社区、野生动物和自然环境，同时减轻消防员的压力——他们今年夏天已经面临了极其严峻的挑战。”

This week's heatwave may not be the last of the summer, according to the Met Office's long-range forecast.

根据英国气象局的长期预报，本周的热浪可能并非今年夏季的最后一次。

"The weather is a bit more changeable in the short term, but as we head more into August there are hints that conditions will settle down and become drier again", said the Met Office's senior operational meteorologist Marco Petagna.

英国气象局高级业务气象学家马尔科·佩塔尼亚表示：“短期内天气会更多变一些，但随着我们进入8月，有迹象表明天气状况将趋于稳定，并再次变得干燥。”

It comes after North Wales and the Upper Severn became the first part of the UK to declare drought status on Thursday last week, with parts of Exeter, Devon and Usk in Wales meeting their heatwave threshold for 20 consecutive days.

此前，北威尔士和塞文河上游地区已于上周四成为英国首个宣布进入干旱状态的地区，而埃克塞特、德文郡的部分地区以及威尔士的乌斯克地区已连续20天达到热浪阈值。

No rain has fallen in July in Bedfordshire, Buckinghamshire, Hertfordshire and West Sussex, and 16 counties have recorded 0.1mm, which Mr Petagna said "might just be a bit of dew on the grass".

贝德福德郡、白金汉郡、赫特福德郡和西萨塞克斯郡在7月份没有降雨，另有16个郡记录到0.1毫米的降水量，佩塔尼亚表示这“可能只是草上的一点露水”。

The UK has had 20% of its average July rainfall, which takes into account the wetter areas.

英国7月平均降水量（已考虑较湿润地区）仅为往年同期的20%。

It is "very, very unusual" for a hot and dry spell to last this long, Mr Petagna added.

佩塔尼亚补充说，持续如此长时间的高温干旱天气“非常非常罕见”。

The dry conditions come after last year's drought summer, with the UK facing more extreme weather fuelled by human-caused climate change.

当前的干旱状况发生在去年干旱夏季之后，而人类活动引发的气候变化正使英国面临更多极端天气。

Meanwhile, wildfires continue to burn in the Cairngorms National Park in Scotland, across the Rhinogydd mountains in North Wales and Blaenavon in South Wales.

与此同时，野火仍在苏格兰凯恩戈姆国家公园、北威尔士里诺吉德山脉和南威尔士布莱纳文等地燃烧。

The last week has also seen blazes on heathland on the Isle of Wight, woodland in the New Forest and fields in Tadley in Hampshire.

过去一周，怀特岛的石楠荒原、新森林的林地和汉普郡塔德利的田野也发生了火灾。

Elsewhere, raging forest fires have forced 300,000 people to evacuate in southern Europe.

在欧洲南部，肆虐的森林大火已迫使30万人撤离。
