Residents of the Gaspé-Percé region and the Magdalen Islands felt the effects of post-tropical storm Arthur Saturday as it made its way inland.
Environment Canada had rainfall, wind and storm surge warnings in effect for both areas.
The warning also said damage to buildings from high winds was possible.
"Damage to buildings, such as to roof shingles and windows, may occur. Gusty winds can damage soft shelters, tents and awnings at outdoor events. High winds may toss loose objects or cause tree branches to break," the warning reads.
By mid-afternoon, Arthur was being blamed for downed tree limbs and power lines around Gaspé.
Hydro Québec reported nearly 23,000 customers without power in the Gaspé region and Magdalen Islands around 3 p.m. ET.
Provincial police also had to close parts of Route 132 in the area of Carleton-sur-mer as a result downed trees and power lines.
Up to 40 millimetres of rain was expected, along with wind gusts of between 90 and 120 km/h in exposed coastal areas.
