The highest 24 hours rainfall totals to 9am today occurred in the Port Macquarie area, where 69mm and 66mm fell at the Port Macquarie Dam and Koala Street rain gauges, respectively.

Several other locations in the Mid North Coast, Upper Hunter and eastern parts of the North West Slopes and Plains reported over 20mm in the 24 hours to 9am.

Mount Seaview has so far collected 25mm today (in the 2 hours to 11am), whilst Glendower Mountain near Tamworth picked up 17mm over the same period.
