Rainfall warning in effect for:
- Cornwall – Lancaster
- Maxville – Alexandria
- Morrisburg – Long Sault
- Winchester – Newington
Rain, heavy at times continues. The ground, already near saturation, has little ability to absorb further rainfall.
40-60 mm of rain expected through Sunday.
Rain will persist through Sunday as the weather system responsible stalls over the region. The rain is expected to taper to showers Sunday afternoon.
With the ground already saturated, there is the potential for local flooding. For information concerning flooding please consult your local Conservation Authority or Ontario Ministry of Natural Resources and Forestry District office.
Localized flooding in low-lying areas is possible. Avoid driving through water on roads. Even shallow, fast-moving water across a road can sweep a vehicle or a person away. Don’t approach washouts near rivers, creeks and culverts. Keep children and pets away from creeks and river banks. Consider moving valuable items to higher levels.
