The summer weather is changing in the United Kingdom and Southern Ontario.

英國與安大略省南部的夏季天氣正在發生變化。

The UK had very strong winds and rain. Some people lost power and a big show stopped. Now, the weather is changing. Experts say the summer will be very hot. Some experts say it will be dry, but others say there will be more rain.

英國先前有強風暴雨。部分地區發生停電，且一場大型表演被迫停止。現在天氣正在變化，專家表示今年夏天將會非常炎熱。部分專家認為天氣會乾燥，但也有人認為雨量會增加。

Some parts of England are very dry. Rivers have less water. Many people used too much water during the heat. Some homes had no water for a short time.

英格蘭部分地區非常乾燥，河流水量減少。許多人在酷暑期間用水過量，導致部分住家短時間內斷水。

In Southern Ontario, it was dry for eleven days. Then, it rained with strong winds and ice. Now, it will be very hot and humid. This can cause forest fires in the north.

在安大略省南部，天氣連續十一日乾燥。隨後出現強風、降雨及冰雹。現在天氣將變得極其炎熱且潮濕，這可能會導致北方發生森林火災。

The weather is not stable. It will get hotter in the next few weeks.

天氣不穩定，接下來幾週會越來越炎熱。

The start of the summer season has been marked by unstable weather in the United Kingdom and a change from long dry periods to heavy rain and storms in Southern Ontario.

夏季之始，英國的天氣不穩定，而南安大略省則由長期的乾旱期轉為大雨與風暴。

In the United Kingdom, summer began with a shift in air pressure and a stronger jet stream, which caused cooler and wetter conditions. This change led to yellow wind warnings in the south, where wind speeds reached 55 mph and peaked at 74 mph at the Needles. Consequently, the final day of the Royal Cornwall Show was cancelled, and there were disruptions to power and transport. While short-term forecasts predict continued instability, including thunderstorms and rain, long-term projections from the Met Office and MeteoGroup suggest a higher chance of heatwaves. The Met Office emphasized that a hotter-than-average summer is twice as likely as it was between 1991 and 2020 due to global warming. However, the two agencies disagree on rainfall; MeteoGroup expects a drier season for England and Wales, whereas the Met Office suggests there may be more rain than usual.

在英國，夏季隨著氣壓轉移與急流增強而開始，導致天氣較為涼爽且潮濕。這種變化導致南部地區發布黃色強風警告，風速達到每小時 55 英哩，並在 Needles 達到最高每小時 74 英哩。因此，皇家康瓦展（Royal Cornwall Show）的最後一天被取消，電力與交通也受到干擾。雖然短期預測預計將持續不穩定，包括雷陣雨和降雨，但英國氣象局（Met Office）與 MeteoGroup 的長期預測顯示熱浪的可能性較高。氣象局強調，由於全球暖化，夏季溫度高於平均值的可能性是 1991 年至 2020 年間的兩倍。然而，這兩家機構在降雨量上存在分歧；MeteoGroup 預計英格蘭與威爾斯將迎來較乾的季節，而氣象局則認為降雨量可能會比平時更多。

Furthermore, the Environment Agency has raised concerns about water security. Although reservoir levels are generally stable, some areas in southern and eastern England had an extremely dry spring, which caused river levels to drop. This pressure on infrastructure was clear when Thames Water reported a one-billion-litre increase in demand during a recent heatwave, and South East Water had to disconnect 18,000 homes due to excessive use. Meanwhile, in Southern Ontario, an eleven-day dry spell ended with the return of rain and the threat of severe thunderstorms with hail. Future forecasts indicate that temperatures will rise to the low 30s with high humidity, which will likely increase the risk of wildfires in northern regions.

此外，環境署對水安全表示擔憂。儘管水庫水位大致穩定，但英格蘭南部與東部部分地區經歷了極其乾旱的春季，導致河流水位下降。當 Thames Water 報告在近期熱浪期間需求增加 10 億公升，且 South East Water 必須因過度使用而切斷 18,000 戶家庭的供水時，基礎設施承受的壓力顯而易見。與此同時，在南安大略省，為期 11 天的乾旱期以雨水的回歸而告終，並伴隨著帶有冰雹的嚴重雷陣雨威脅。未來預測指出，溫度將升至 30 度出頭且濕度較高，這可能會增加北部地區發生山火的風險。

Weather conditions remain unstable in both regions, but temperatures are expected to rise and rainfall levels will vary in the coming weeks.

兩個地區的天氣仍然不穩定，但預計未來幾週溫度將上升，且降雨量將有所不同。

The onset of the meteorological summer has been characterized by significant atmospheric instability in the United Kingdom and a transition from prolonged aridity to convective activity in Southern Ontario.

氣象夏季的開始，在英國表現為明顯的大氣不穩定，而南安大略省則是由長期乾旱過渡到對流活動。

In the United Kingdom, the transition to summer commenced with a shift from high-pressure systems to a more potent jet stream, precipitating a period of cooler, pluvial conditions. This atmospheric reconfiguration resulted in the issuance of yellow wind warnings for southern regions, where gusts reached 55 mph, with peak recordings of 74 mph at the Needles. Such conditions necessitated the cancellation of the final day of the Royal Cornwall Show and induced disruptions in power distribution and transport. While short-term forecasts indicate continued variability—including potential thunderstorms on Tuesday and widespread precipitation on Thursday—long-range projections from the Met Office and MeteoGroup suggest a higher probability of heatwaves. The Met Office posits that the likelihood of a hotter-than-average summer is approximately double that of the 1991–2020 reference period, attributing this trend to climatic warming. However, divergence exists regarding precipitation; MeteoGroup anticipates a drier season for England and Wales, whereas the Met Office suggests a potential for above-average rainfall.

在英國，進入夏季是由高壓系統轉變為更強的噴射氣流開始，導致一段時間的低溫與多雨天氣。這次大氣重新配置導致南部地區發布黃色強風警告，陣風達到每小時 55 英哩，而 Needles 記錄到最高時速達 74 英哩。這些情況導致皇家康沃爾展覽會 (Royal Cornwall Show) 最後一日被迫取消，並造成電力配送與交通中斷。雖然短期預報顯示天氣將持續波動——包括週二可能出現雷陣雨，週四有大範圍降雨——但英國氣象局 (Met Office) 與 MeteoGroup 的長期預測指出，熱浪出現的機率較高。英國氣象局認為，夏季溫度高於平均值的可能性約為 1991-2020 年參考期的兩倍，並將此趨勢歸因於氣候暖化。然而，關於降雨量存在分歧；MeteoGroup 預計英格蘭與威爾斯將是一個較乾的季節，而英國氣象局則認為降雨量有可能高於平均水準。

Institutional concerns regarding water security have been highlighted by the Environment Agency, noting that while reservoir levels generally remain stable, specific regions in southern and eastern England experienced an exceptionally dry spring. This deficit has led to a notable decline in river levels. The vulnerability of infrastructure was evidenced by Thames Water's report of a one-billion-litre increase in demand during a recent heatwave, and South East Water's reported disconnection of 18,000 households due to excessive consumption. Parallelly, in Southern Ontario, an eleven-day period of aridity concluded with the return of precipitation and the threat of severe thunderstorms involving hail and gusty winds. Subsequent projections indicate the development of a ridge, which is expected to elevate temperatures into the low 30s and increase humidity, thereby exacerbating wildfire risks in northern regions.

環境署 (Environment Agency) 提出對水資源安全的機構關注，指出雖然水庫水位普遍維持穩定，但英格蘭南部與東部部分地區經歷了異常乾旱的春季。這種不足導致河流水位明顯下降。基礎設施的脆弱性在 Thames Water 的報告中得到證實，最近一次熱浪期間需求增加了 10 億公升；而 South East Water 則報告由於用水過量，有 18,000 戶家庭被切斷供水。與此同時，在南安大略省，為期 11 天的乾旱期隨著降雨回歸以及包含冰雹與強風的嚴重雷雨威脅而結束。隨後的預測顯示將形成高壓脊，預計會將溫度提升至 30 度初並增加濕度，從而加劇北部地區的山火風險。

Current conditions remain unstable across both regions, with a transition toward higher temperatures and varying precipitation levels expected in the coming weeks.

目前兩個地區的情況依然不穩定，預計未來幾週將轉向更高溫與不同程度的降雨。
