Periods of heavy rain and thunderstorms are expected to bring the potential for significant rainfall on Tuesday.
We could get total local rainfall amounts of 50 to 100 mm with rainfall rates of 30 to 50 mm per hour.
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.
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.
A special weather statement has been issued for:
- North Bay - West Nipissing - French River
- Powassan - Mattawa
- South River - Burk's Falls
- Greater Sudbury and vicinity
- Temiskaming Shores - Temagami,
- Huntsville - Parry Sound
Heavy downpours can cause flash floods and water pooling on roads. Watch for possible washouts near rivers, creeks and culverts.
