High water has "cut off" areas of southwestern England after torrential rain pelted the U.K.
Flood warnings were posted for the South West, Midlands and other areas of England, the BBC News website said on Wednesday.
Flooding shut schools, blocked some roadways and hampered public transportation in the area.
Fire services in Devon and Somerset were called 18 times to rescue people from flooded cars.
Some villages in the area were made "impassible" by high water.
"I've lived here 21 years and I've never seen it flood," one area resident was quoted as saying.
Rainfall as of Wednesday was 2.6 inches within 36 hours at both Exeter and Dunkeswell, data accessed by AccuWeather.com showed.
The U.K. faces more rain, some heavy on Thursday, so flooding problems could recur.
The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
