More than 13,000 Hydro One customers across parts of central and northern Ontario were without power Tuesday afternoon.

Hydro One has not yet specified a reason for the outages, but it comes as blustery conditions are expected ahead of a cold front moving across the province.

A wind warning covering the Parry Sound, North Bay and Kirkland Lake areas was issued Tuesday, with gusts of up to 90 kilometres an hour expected.

Nearly half of the customers affected, about 5,900, are in the Sudbury area.

Other regions with significant numbers affected by outages include Timmins, Kapuskasing, Kirkland Lake, Parry Sound and Huntsville.
