People living near rivers and streams may see a "noticeable increase" in water levels in the next two days as the temperature continues to warm up, according to the Emergency Measures Organization’s River Watch program.
The advisory says Environment Canada is forecasting temperatures to be above freezing for the next 48 hours.
"Residents will see a noticeable increase in water levels in streams, tributaries and rivers over the next 48 hours," according to the advisory.
The organization is warning people who live or work near rivers, streams or tributaries to be on alert for possible flooding.
Boaters, kayakers and others are also advised to avoid the water due to strong currents and debris being carried along.
There have been incidents of localized flooding so far this spring.
An ice jam caused an evacuation order in the small village of Stanley in March.
The province's Emergency Measures Organized put in place a new flood monitoring system in 2013, following a major flood in the Perth-Andover area last year.
