This question already has an answer here:

What is the usual way to report surface pressure in weather forecasts online, in smartphone apps, on TV/radio? Is it the actual local pressure or the sea-level adjusted value? Does it differ by country?

Update: For example, English Wikipedia article on Atmospheric pressure says mean sea-level pressure is normally given in weather reports. And Russian Wikipedia article says the actual pressure is used. After some research I can say, that English weather websites I've seen report sea-level pressure and Russian weather websites mostly report actual pressure, but some of them report sea-level pressure.
