Pirelli have confirmed the Jerez circuit will be artificially watered on Friday in order to allow for wet running.
This week the teams will take to the Spanish circuit for the first of the three pre-season tests.
The four days of action kick off on Tuesday in what is expected to be chilly conditions.
And although there is a possibility of rain during the week, should it not come before Friday the track will be artificially watered on the final day.
"The new regulations stipulate that one of the pre-season test days will be dedicated to wet weather testing of our new Cinturato intermediate and wet tyres," said Pirelli motorsport director Paul Hembery.
"This is scheduled for the final day at Jerez, in order to give the teams experience of a wide range of conditions as soon as possible as they refine their 2014 cars."
Pirelli announced they had also brought with them a special one-off 'winter' tyre to Jerez to compensate for the low temperatures.
Pirelli stated: "This is a hard compound that has been optimised to work well even in low temperatures, reducing the risk of graining (which is a common characteristic of cold weather running)."
