Hurricane Isaias, strengthened to Category 3 as of Friday morning, is tracking north from the Gulf of Mexico and could bring rain to the GTA over the Thanksgiving long weekend.
Rain is most likely to arrive Sunday, Oct. 13, with the possibility of showers continuing into Monday, Oct. 14, depending on the storm's exact path. The Weather Network cited an unusual lack of high-pressure systems as a reason the hurricane's remnants could track toward the Great Lakes by early Sunday. Another outlet reported rainfall expected Sunday, with showers possible Monday morning before afternoon sun breaks through.
Friday and Saturday will remain largely dry. Friday's forecast calls for a mix of sun and cloud with a high of 19°C and windy conditions, with an overnight low of around 9°C. Saturday looks similar—sun and cloud, high 19°C, low around 12°C—though early morning fog is possible.
The exact rainfall amount remains uncertain, as does whether rain will extend fully into Monday, since the storm's northward track is still in flux. Residents are encouraged to monitor updates through the weekend as the forecast may shift with Isaias's movement.
