A burn ban has been issued for Ottawa with the hot and humid conditions expected to grip the capital through the weekend. The Ottawa Fire Services issued the burn ban on Friday morning. All open-air fires are prohibited during a burn ban, including fires at properties that have an Open-Air Fire Permit. “This ban applies to agricultural burns, brush pile burns, as well as campfires,” the Ottawa Fire Services said in a statement. “There will be zero tolerance enforcement during the fire ban as per the Open-Air Fire By-law No. 2004-163.” The forecast calls for highs of 30 C on Saturday and Sunday, and 32 C on Monday. Ottawa has received 48 mm of rain so far in July and has seen seven days with the temperature above 30 C. Environment Canada reported 8.4 mm of rain at the Ottawa Airport Friday night as a series of storms moved across the region.
