How to read the Perth and the South West rainfall map
The palest shading marks falls of a millimetre or two. Blues and greens through 10 to 30 mm usually mean a useful soaking for gardens and pasture. Yellow and orange from 30 to 100 mm point to heavy rain that can flood low-lying roads, while red, pink and purple above 100 mm indicate the sort of totals that bring flash flooding, especially in a short burst.
Totals are a broad regional guide rather than a suburb-by-suburb measurement. Thunderstorm rainfall is the hardest part to place and timing can run a few hours early or late, so check radar and current warnings close to the event. For the other period, see the Perth and the South West 7 day rainfall forecast.
Using the Perth and the South West rainfall forecast safely
This map is forecast guidance, not a warning. Totals change with every model run, and a single storm can drop far more rain on one catchment than the map suggests. Official rainfall, flood and severe weather warnings from the Bureau of Meteorology always take priority for Perth and the South West. Never drive through floodwater.
For rain already falling, use the rainfall radar and observations. For storm risk, see the Perth and the South West thunderstorm forecast map.
