Rainfall Warning Issued for Kingston

More rain is in the forecast for an already waterlogged Kingston area, prompting Environment Canada to issue a rainfall warning.

Rainfall warnings are issued for amounts of 25 millimetres or more in 24 hours or less when the ground is already saturated.

Rain on Thursday is forecast to be heavy at times, with between 20 and 35 millimetres expected.

Environment Canada says the rain will change to snow overnight, dropping around 2 centimetres, before clearing on Friday.

Gusty winds up to 70 kilometres per hour are also possible, which could cause some blowing snow problems for drivers.

While widespread flooding is not expected, the Cataraqui Region Conservation Authority says localized flooding, especially near creeks, rivers, and other bodies of water is likely or already happeneing.

CRCA watersheds received around 50 millimetres of rain on Monday and Tuesday, causing bodies of water to rise considerably.

Water control structure managers have been proactively operating structures and moving water between lakes to prepare for the runoff, and any additional rainfall, to minimize the potential for flooding.

Thursday's rain is expected to cause rapid increases in stream levels and lake levels and already flooded areas are expected to exceed a normal spring event.

There is still ice on some lakes, and the changing water levels will lead to ice breakup which could cause ice jams and flooding at narrowing points like as bridges and culverts.
