OTTAWA, May 13 (Reuters) - Canada's main oil-producing province of Alberta faces another hot and dry weekend, with warnings of more intense wildfires after blazes forced thousands to evacuate homes and temporarily shuttered energy production. Residents forced to evacuate early this month say they are frustrated with the indefinite displacement. "We are expecting hot and dry conditions in most of the province, which will make the wildfire danger climb," Alberta Wildfire official Josee St-Onge told a briefing on Friday. Recent cooling and rain helped firefighters tackle some blazes and restored most of the energy production, but expectations of rising weekend temperatures have fanned worries. On Friday, the town of Drayton Valley told residents in a Facebook post that they should expect to be out of their homes "at least another week."
