Weather Situation – Northern Western Australia
A weak trough lies near the Kimberley and Pilbara coasts and extends down the
Gascoyne coast. A high pressure ridge is strengthening over northern parts of
the State, increasing the east to southeasterly flow and pushing the trough
offshore during the morning period.

A firm high pressure ridge extends through most of the State with the
associated high pressure centre moving across the Southern Ocean to lie south
of the Bight by Monday. A trough near the Gascoyne coast connects to a low

west of the South West Capes on Monday. The trough will move east on Tuesday,
crossing the west coast in advance of the next cold front across the western
