Weather Situation
The east to southeasterly surge across coastal waters will ease from today, but east to southeast winds will continue due to a slow moving ridge over northern Australia. The ridge is expected to slowly weaken this week. Meanwhile, a patchy cloud band may bring light showers to western Pilbara waters today, before clearing on Tuesday.
