A tropical low that brought Innisfail's wettest April run in 63 years is heading towards Brisbane. Innisfail has borne the brunt of the rainfall this week with a record run of more than 15mm every day for eight days. During the last two days the coastal town has gained more than 170mm. Elsewhere the heavy showers have come and gone in Mackay and Maroochydore with a total of 198mm and 128mm in the past four days respectively. In Brisbane there has only been the odd light shower or two this week with onshore winds bringing cloud and increased humidity. Today, cloud will remain over the capital with a few showers rolling in, but still nothing substantial. Tonight showers will increase across Southeast Queensland with heavy rain a risk from the Sunshine Coast to the NSW Northern Rivers on Saturday. This stretch of coastline should see widespread totals of 25-50mm, including Brisbane. Falls above 80mm are possible in this region, although the heaviest rain is likely on the Sunshine Coast. By Sunday morning showers will have eased significantly for most locations with barely any showers in the region by the evening. Sunday afternoon will be the best opportunity to get out and about during the weekend.
