Formula 1 is in for a very wet United States GP weekend, although the rain will lessen ahead of Sunday's race.
According to F1's official weather forecast provider Ubimet, a low pressure system from the west coming into contact with a lot of moisture from the Gulf means heavy showers on the cards.
Friday's high will be 25'C but it is going to be wet and thundery throughout the day with both practices taking place in the rain.
There is more of the same on Saturday where drivers can expect a wet qualifying session.
"During the afternoon some further, but weaker showers are still expected, so the starting grid could easily be jumbled by the rain too," Formula 1 Chief Meteorologist Steffen Dietz said.
Sunday will have the better of the conditions with isolated showers. Those will not be as intense as the previous two days while the high temperature for the grand prix will be 22'C.
