Environment Canada has issued a special weather statement for Kingston, Ontario, warning of heavy rain moving into the region this weekend. A low-pressure system known as a Colorado low is expected to bring between 25 and 50 millimetres of rain to the area, with the heaviest downpours occurring Saturday evening and Saturday night, April 4, 2026.
The weather system may also trigger thunderstorms, which could lead to higher rainfall totals in some locations. Residents are encouraged to monitor local updates from Environment Canada as additional weather alerts may be issued if the situation intensifies.
The Cataraqui Conservation Authority has extended a water safety statement for the region, noting that recent rainfall has already pushed streamflows to 1.5 times their normal levels for early April. Because the ground currently has limited ability to soak up more water, authorities warn that this weekend’s rain will likely result in increased runoff.
While officials do not expect widespread flooding, they are advising residents to be aware of possible water buildup in low-lying areas. The conservation authority previously issued a flood watch in March 2026 due to the spring melt, during which several local creeks, including Wilton, Millhaven, Collins, and Lyn creeks, reached all-time high flow levels.
For residents concerned about property protection, the City of Kingston has sand and sandbags available at the Creekford Road public works site. Residents can contact the city at 613-546-0000 for more information regarding these supplies.
