Heavy rain in association with Storm Boelo is expected to lead to surface water flooding in places. 25-30mm is expected widely across the warning area during this time, with a few places such as upland areas seeing 50-60mm, and some of this perhaps falling within 6 hours. Rain will ease for a time through the evening, but this will be followed by another intense band of heavy rain following in from the west, before the whole system clears away eastward to bring a clear night with a few scattered showers following on.
