Update: A severe thunderstorm is expected to produce large hail in the South East Coastal forecast district.

A warning has been issued people in the area bounded by Hopetoun, Salmon Gums, Balladonia and Israelite Bay and includes people in or near Esperance.

As at 4.33pm the Bureau of Meteorology advised that a strong cold front would cross the west coast near midnight, between 11pm and 1am, with a fast moving line of heavy showers and thunderstorms.

Damaging and locally destructive winds are possible as this line of thunderstorms moves through the area. Winds will ease after the front moves through but will strengthen again during tomorrow morning.

A severe weather warning has also been issued for tomorrow for people in the Central West, Lower West, South West, South Coastal and Great Southern forecast districts.

The warning includes people in, near or between the following towns: Jurien Bay, Perth Metropolitan area, Mandurah, Bunbury, Busselton, Margaret River, Bridgetown, York, Narrogin, Katanning and Albany.

A deep low pressure system is expected to move along the south-west of the State during tomorrow.

Abnormally high tides which may cause sea water flooding of low lying coastal areas are forecast for the Lower West forecast district and parts of the Central West and South West forecast districts.

Widespread damaging winds to 100 km/h are forecast for the Lower West and South West forecast districts and parts of the South Coastal and Great Southern forecast districts.

Dangerous gusts in excess of 125km/h are possible in localised areas.

These conditions are highly unusual, especially for this time of year, they are more typical of a strong cold front during winter.

The Department of Fire and Emergency Services advises that people should:

- Store or weigh down loose objects such as outdoor furniture.

- Have an emergency kit with a battery operated radio, torch, spare batteries and
first aid kit.

- Ensure pets and animals are in a safe area.

- Move vehicles under cover.

- Boat owners should securely moor their boats.

- Campers should find shelter away from trees, power lines, storm water drains and streams.

If your home or property has significant damage, like a badly damaged roof or flooding, call the SES on 132 500.
