Understanding rain
The precipitation probability says how certain rain is at a place, not how much: 30 % means measurable rain falls on three out of ten days with this weather pattern.
The precipitation amount in millimetres is water per square metre; one millimetre is one litre. Below 1 mm per hour the rain stays light, above 4 mm it is heavy.
Showers are short and local and can often be forecast reliably only a few hours ahead. The rain radar and its nowcast show where they are heading in the next two hours.
