Environment Canada has issued both a wind warning and a rainfall warning for Kingston and the area, advising that those in the area “should be on the lookout for adverse weather conditions and take necessary safety precautions.”

The warnings, issued around 3:30p.m. on Friday, Dec. 10, 2021, are in effect for the Kingston, Odessa, Frontenac Islands, Napanee, Consecon, Picton, and Sand Banks Park areas, and note that hazardous strong winds gusting between 100 and 102 km/h are possible. These winds are expected to begin late in the afternoon or in the early evening on Saturday, Dec. 11, 2021, and continue overnight.

“A cold front will sweep through southern Ontario Saturday afternoon and evening bringing strong winds,” Environment Canada said in the wind warning.

These winds could result in utility outages, and damage to buildings, such as to roof shingles or windows, may occur, the national weather agency said.

“High winds may cause downed trees or toss loose objects. Store or anchor objects so they are not tossed by the wind causing injury or damage. Be prepared to adjust your driving with changing road conditions due to high winds.”

In terms of the rainfall warning, Environment Canada said that the area is in store for rain, heavy at times, which could result in rainfall amounts of 20 to 40 mm. The rain is expected to begin late in the evening of Friday, Dec. 10, 2021, and continue through Saturday afternoon.

“A strengthening low pressure system is forecast to track northeast across the Great Lakes on Saturday, bringing heavy rain,” the rainfall warning states.

“The frozen ground has a reduced ability to absorb this rainfall. Melting snow will also contribute to runoff.”

According to Environment Canada, heavy downpours can cause flash flooding and water pooling on the roadways. Residents are advised of the possibility of localized flooding in low-lying areas, and to watch for possible washouts near rivers, creeks, and culverts.

Areas such as Front Road near Cataraqui Bay, King Street on the waterfront side of KGH, and the underpass on Gardiners Road frequently wash out in Kingston. Avoid those areas during heavy rainfall if possible.

Kingstonist will continue to monitor this situation and provide updates as more information becomes available.
