SPECIAL WEATHER STATEMENT
Freezing rain, followed by significant rainfall midweek. What: Freezing rain with ice accretion of 2 to 5 mm on some surfaces. Surfaces such as highways, roads, walkways and parking lots may become icy, slippery and hazardous. Ice build-up may cause tree branches to break. Rain, at times heavy. Total rainfall amounts of 20 to 40 mm. Locally higher amounts are possible in thunderstorms. When: Wednesday morning through early Thursday morning. Additional information: This freezing rain event will not be nearly as significant as the ice storm from this past weekend. The potential for freezing rain begins east of Lake Huron Wednesday morning before reaching eastern Ontario later Wednesday afternoon into Wednesday evening. Precipitation may begin as snow and ice pellets, especially over central and eastern Ontario. Easterly winds gusting to near 50 km/h on Wednesday may exacerbate any tree damage. As temperatures rise above the freezing mark, freezing rain will transition to rain over southwestern Ontario through Wednesday afternoon and across central and eastern Ontario Wednesday night. For locations along the Ottawa River, freezing rain may persist into early Thursday morning. Freezing rain warnings will likely be required as the event draws nearer. Localized flooding in low-lying areas is possible. For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources office.
