Freezing Rain Warning

The leading edge of precipitation in the form of rain has moved along the 401 towards Brockville. It will be in the Kemptville area by 8:45am and towards Ottawa by 9am. Temperatures at the surface remain below freezing, and several hours of freezing rain is forecast for our region. Around 2-4mm of ice accretion may occur before the change to rain by noon in most areas. The change will occur first in the St. Lawrence Seaway and after lunch in the upper Ottawa Valley. Many roads have been pre-treated this morning with salt and sand, but any that are not will become slippery quickly as the rain begins. A Freezing Rain Warning is in effect for Kemptville, Leeds and Grenville and most of the Ottawa Valley. Once temperatures warm into the low single digits they will remain above freezing most of the weekend, with plain rain and gusty winds forecast.
