Temperatures across Japan to rise sharply on Sunday, raising heatstroke risk
Temperatures are expected to rise sharply across wide areas of Japan on Sunday, with summer-like weather above 30 degrees Celsius expected in the eastern region of Kanto-Koshin.
Officials are calling on people planning outdoor activities in the areas to be affected to take precautions against heatstroke, such as a frequent intake of salt and water.
The Japan Meteorological Agency says daytime highs will reach 30 degrees Celsius in the cities of Kofu in Yamanashi Prefecture, Saitama in Saitama Prefecture and Maebashi in Gunma Prefecture.
Daytime highs of 29 degrees Celsius are expected in the cities of Kyoto, Nagoya and Fukushima, as well as central Tokyo, and 28 degrees Celsius in Kochi City. These temperatures are as high as those usually seen in late June to mid-July.
The meteorological agency also expects that atmospheric conditions will become extremely unstable, mainly in the Kanto region in the afternoon, and the weather could suddenly change with the possibility of thunderstorms.
Caution is advised against lightning strikes, gusts, and strong winds such as tornadoes, sudden downpours and hail.
People are also advised to seek shelter in sturdy buildings when there are signs of thunderclouds approaching.
