Execssive heat
Very hot weather is expected with temperatures reaching up to 30 degrees or just over 30 degrees.; What happens?: A high pressure has established itself just west of the country and is bringing warm air across the country. The warmest days look to be Wednesday and Thursday with temperatures around or just above 30 degrees. The nights will also be fairly warm, making it difficult to ventilate heat that has accumulated indoors. On Friday, the temperature will also approach 30 degrees, but it may be slightly lower depending on the amount of cloud cover and if any showers form. Cooler weather and rain will then take over during the weekend.; What should I think about?: Be aware of warning signs, both regarding yourself and people around you.
Drink more water, take it easy and find ways to cool down. Try to create a cool environment, keep an eye on the indoor temperature.; Where?: Large parts of mainland Götaland and Svealand as well as southernmost Norrland
