The island has endured a record-breaking deluge.
Some 49.5mm of rain fell between 9am on Monday and 9am on Tuesday.
That’s almost as much rain in 24 hours than you would expect to get in the whole month of April.
The long-term 30 year average for April is 54.4mm
The previous wettest April day was in 1971 when 38.5mm of rain was recorded.
Met Office forecaster George Shimmin said there has only been three occasions before when more than 30mm of rain was recorded over a 24 hour period in April.
He said: ‘This was particularly extreme and very rare for April.’
The deluge made driving conditions very difficult during the morning rush hour, with plenty of standing water on many roads.
It comes after a wetter than average winter, and a very wet March. April will be the fifth consecutive month with above average rainfall.
A warning for heavy rain and flooding was issued on Sunday and upgraded to Amber on Monday.
The unsettled weather is set to continue with the next band of rain due to sweep in around 8-9am tomorrow.
