Authorities say valuable lessons can be learnt from the timing of Western Australia's first tropical cyclone of the season.
Far northern communities were placed on blue alert on Saturday afternoon, as category one ex-Tropical Cyclone Alessia approached.
The Department of Fire and Emergency Services (DFES) says mines were evacuated and communities prepared in time and the all clear was given late on Sunday.
DFES' Lee Vallance says it is the first time in five years a cyclone has formed in November and it is a good reminder to be prepared.
"Even though it was a low category one, it just sort of gives everyone a heads up that we ... can expect cyclones all the way through to May next year but everyone should have plans in place and everyone should do preparatory work to make sure all the potential projectiles around the house are cleared up," he said.
He says the experience allowed for cyclone plans to be tested out.
"It was good, it gives us a chance to liaise with all our stakeholders, liaising with police and industry and all our volunteers that we utilise and just getting everything together and everyone talking to make sure we're all reading off the same sheet of music," he said.
