On Friday, thousands gather in the audience at Ullevi in Gothenburg to see the first of Håkan Hellström's four concerts.
At the same time, an area of rain is approaching from the south, which is expected to arrive in the city and the region during the afternoon and evening.
- Exactly where the showers will end up is difficult to say, but they will probably pass Gothenburg, says Marcus Sjöstedt, who explains that there is also a risk of thunder in connection with the showers.
"Can be a good shower"
At the same time, he emphasizes that it is extremely difficult to make forecasts about this type of shower.
- If the strongest shower hits just above Ullevi, it can be a proper shower with several millimeters.
SMHI has issued a yellow warning for torrential rain throughout Västra Götaland from Friday afternoon to early Saturday morning.
Which parts will be affected is thus uncertain.
Uncertain prognosis
But on Saturday, when Håkan Hellström has his second concert, the weather looks different.
- Then it points more towards lingering weather at the moment.
But there are uncertain forecasts so it may be good to check the forecast tomorrow as well, says Marcus Sjöstedt.
