Environment Canada has issued a Special Weather Statement for areas including Petawawa, Pembroke, Cobden, Renfrew, Arnprior and Calabogie.
“Periods of heavy rain and thunderstorms are expected to bring the potential for significant rainfall on Tuesday,” reads the statement.
Experts say total local rainfall amounts of 50 to 100 mm are possible with rainfall rates of 30 to 50 mm per hour possible late this afternoon through tonight.
“Multiple rounds of showers and thunderstorms are expected to track along a stalled front, which may lead to a narrow swath of significant rain. Rainfall warnings may be required and issued with short notice to reflect the rapidly changing conditions,” reads the statement. “It is currently uncertain how showers and thunderstorms in this area will evolve. Atmospheric conditions and where the front stalls will be strongly influenced by convection tonight and early Tuesday morning over the US Midwest.”
Officials say heavy downpours can cause flash floods and water pooling on roads.
“Watch for possible washouts near rivers, creeks and culverts.”
For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources and Forestry office. Visit Ontario.ca/floods for the latest details.
