Flash-flood watch in effect for western and north-western districts

This alert message is valid from 12 noon Saturday and will be terminated at 6 p.m. or sooner if conditions warrant.

A flash-flood watch is issued when heavy or excessive rainfall in a short period of time (generally less than six hours) could result in flash flooding within the watch area.

It does not mean that flooding will occur, but it is possible.

Hazard Info: A light wind regime and abundant low-level moisture could result in some localised shower activity over some western and northwestern districts. Rainfall accumulations of 20.0 to 40.0 mm in moderate to heavy showers are possible in the watch area.

Key Message: Residents and visitors should be prepared for strong runoff from higher elevations. Soil erosion likely on bared or scarred land surfaces. Debris such as small rocks, mud and tree foliage could end up on roads and property. Traffic delays are likely. Flooding at the foot of hillsides and coastal roads is possible.
