[Desmond] gained strength as it traversed the Atlantic Ocean, drawing a huge amount of moisture from the Caribbean. This “atmospheric river” was seen clearly on satellite images of precipitable water — something meteorologists use to determine how much moisture is available for a storm to convert into rain....An incredible 13.44 inches of rain fell in 24 hours at Honister Pass in the Lake District. The total sets a new record for 24-hour rainfall at the location...The previous record for 24-hour rainfall was 12.45 inches at Seathwaite, Cumbria, in November of 2009. 15.94 inches of rain fell at Thirlmere — also in the Lake District — in just 48 hours, which also set a new record for the 48-hour period. The previous 48-hour rainfall record was 15.57 inches, which was also set at Seathwaite in November 2009
