Return value of $wi(press)$mbar is for ex. 33051.17 what is 33051.17hPa, this is wrong.
Yeah definitely 33051 HPA is not suitable for life :)
So, pressure is fetched by the weather provider, which one are you currently using? Does changing the weather provider fix this?
Yahoo is fetching this wrong value. Others are ok :-)
Cool, will try to see whats going on
Unable to reproduce so probably a glitch in Yahoo output on your contry
