There are further heavy isolated showers forecast for today, Monday 24 July. Some of these showers could cause river levels to rise quickly but it is difficult to forecast exactly where the showers will occur as they will be very isolated. This also means that each shower will be short lived and some places may not see much rain at all. Some places may see more than 1 shower though which is what will impact river levels. There may also be standing water in roads and low lying land where the heaviest showers occur. We are constantly monitoring river levels and have staff on standby to attend to any blockages in the river that we become aware of.
