An outbreak of severe thunderstorms will develop across much of WA during the middle of this week, with the potential for damaging winds and unseasonably cold and wet conditions following it.
This dynamic thunderstorm period will be generated by a low pressure trough sitting across western WA and a deep low pressure system which will increase activity on Wednesday as it moves over the state.
Thunderstorms should begin on Tuesday over the Pilbara, Kimberley, Gascoyne, Goldfields and the South West Land Division on Tuesday in response to the low pressure trough.
