Rainfall will increase from Saturday with daily rainfall totals of 40-100 mm, with isolated heavier falls above 150 mm possible.

Significant river, creek, and stream rises are likely with heavy rainfall, with flooding possible across parts of the Flood Watch area from late Friday.

Many roads, and possibly primary and secondary highways may be affected. Some communities and homesteads may become isolated. Check road conditions before travelling.
