Wind warning in effect for:

  • Niagara Falls – Welland – Southern Niagara Region
  • St. Catharines – Grimsby – Northern Niagara Region

Strong winds that may cause damage are expected or occurring.

Strong southwest winds with gusts of 90 km/h are expected this afternoon. The strongest winds are expected along exposed areas near the lakeshore as well as over higher terrain.

These winds will shift to the northwest with the passage of a sharp cold front early this evening. Northwest wind gusts of 70 to 80 km/h are expected this evening.

Winds will diminish late this evening and overnight.

These strong winds may cause some tree damage and isolated power outages, because many trees are still in partial to full leaf.

Loose objects may be tossed by the wind and cause injury or damage. High winds may toss loose objects or cause tree branches to break.

Wind warnings are issued when there is a significant risk of damaging winds.
