Rainfall warning in Hamilton for the second day in a row


Published June 8, 2022 at 8:19 pm

A wet Wednesday night is in the offing for Hamilton, one day after a heavy rainfall in the city.

Shortly before 7 p.m., Environment and Climate Change Canada issued a special weather statement for the city, saying 10 to 25 millimetres of rain could fall tonight and overnight into Thursday. Some low-level flooding is possible since the ground has already absorbed ample amounts of water over the past few days.

“Light rain has already begun over regions along the southern and eastern shores of Lake Huron and northern shore of Lake Erie,” the federal weather agency stated. “Heavier showers are expected to move in later this evening. The ground may have a reduced ability to absorb this rainfall due to the recent heavy rainfall.”

For information concerning flooding, people consult their local Conservation Authority. Further information is available at ontario.ca/floods.

On Tuesday, 18.3 mm of rain fell in Hamilton, making it the wettest June 7 in three-quarters of a century. The previous high within the past 50 years was 17.8 mm, set most recently in 1980.

Environment and Climate Change Canada records show that Hamilton received 42.0 mm of rain in the first seven days of June. The rain has led to sports fields being closed, affecting organized outdoor activities that were limited and paused during the ongoing COVID-19 pandemic.

That’s nearly as much rain as Hamilton received in all of June 2020. However, that was the driest June the city has had in the last decade.
