It has been one of the most exceptional periods of winter rainfall in 240 years, according to the Met office.
Kirk Waite, forecaster for the Met Office said December 2013 and January 2014 had been the wettest period since 1876.
Speaking ahead of this weekend's expected deluge, Mr Waite said: “It’s not that unusual about the amount of rain that we are going to see but the fact that it’s all this rain coming after a wet two months, which is causing saturation.
“Cornwall has seen around 10mm of rain in some spots in the last 12 hours.
“The main impact for Cornwall is going to be East Cornwall, which has an amber wind warning with gales up to 70mph and risks of 80mph winds in exposed places.
“This will bring large waves- however the winds are going to change direction from a south easterly wind to a south westerly wind.
“This will see different areas impacted with the strongest waves- the coastal areas will be most affected.”
There is an amber warning for East Cornwall on the border with Devon and a yellow warning for the rest of Cornwall, according to Mr Waite.
There is more rain expected in the West of Cornwall tomorrow around 6pm according to the Met Office.
