Weather Situation

The next five days starting Friday (April 29th) there are no major precipitation events that could impact the province barring some occasional rainfall for southern region in the amount of 10 to 30 mm cumulatively for the upcoming five days. Included in the above forecast is a possible rainfall in the amount of a 10 to 20 mm for the Southeast Region on Sunday and into Monday. Rainfall amount of 10 to 20 mm cumulative for the next five days is forecast for the northeast with some of it likely to be snow for northern sectors of the region. Daytime high temperature will be around the 0 to 10 degrees centigrade range for northern sectors of the northeast and progressively warmer into the south reaching up to a high of 15 degrees centigrade during the next five days. Nighttime temperature lows will be sub-zero degrees centigrade for northeast and up to 5 degrees centigrade for the south in this time period.


Water levels and flows across much of central Ontario continues to remain elevated from past precipitation and snow melt and is currently stable or receding at most gauging stations. The forecast rain and snowmelt from warm temperatures could likely cause water levels and flows to rise across northern sectors of south-central Ontario.

Further northeast, snow melt is occurring, and water levels and flows are continuing to rise or stabilising due to colder weather but still high. As the temperatures drop in the nighttime the melt will be slower but the water levels and flows will likely continue to increase but at a slower rate.

A close watch on water levels and flows and local weather conditions is recommended.

This message will be in effect until (or updated before) Monday, May 2nd, 2016 at 12:00 pm.
