About 55 mm of rain fell across the London area on Wednesday, raising water levels along the Thames River, flooding Gibbons and Harris Parks by Thursday afternoon.
The London region is drying off after a day-long rain event that dumped nearly a month’s worth of precipitation on the city in roughly 24 hours, Environment Canada said.
The national weather agency says London’s airport recorded roughly 62.5 mm of rainfall from Wednesday morning overnight into Thursday, making it one of the top five wettest April days on record.
Most other areas around the city saw between 50 to 60 mm of rain in the period, with some exceptions, said Steven Flisfeder, a meteorologist with Environment Canada.
“There was one report of 74 millimetres that came from Ilderton; that was a volunteer report,” he said, adding that overnight thunderstorms helped push up precipitation figures in some localized areas.
