The Bureau of Meteorology has issued a severe thunderstorm warning for “damaging winds” set to hit much of the south and south west of WA.

The warning was issued on Monday afternoon for towns including Bunbury, Busselton, Margaret River, Augusta, Dunsborough and Walpole.

“A cold front is expected to move across the southwest of the state from late Monday afternoon into the evening, bringing gusty showers and possible thunderstorms,” BOM said.

Marked as “the first significant cold front of the year,” peak gusts of up to 100 km/h are possible across the South West Capes by early Monday evening, before extending further eastwards and northwards throughout the evening and overnight.

Conditions are expected to ease by Tuesday morning and live updates can be found on the BOM website.

The Department of Fire and Emergency Services has issued safety advice to those in affected areas, including:

• If outside find safe shelter away from trees, power lines, storm water drains and streams.
• Close your curtains and blinds, and stay inside away from windows.
• Unplug electrical appliances and do not use land line telephones if there is lightning.
• Be alert and watch for hazards on the road such as fallen power lines and loose debris.
• Keep away from flooded drains, rivers, streams and waterways.
• Be careful of fallen trees, damaged buildings and debris.
• Be careful of fallen power lines. They are dangerous and should always be treated as live.
