Innisfail and South Johnstone gained over 250mm in a two day deluge, nearing May rain records.
Rain has been dumping along the Queensland North Tropical Coast for the past two days. Innisfail gained 116mm to 9am yesterday, its heaviest May rain in 17 years. This morning it surpassed that total with a whopping 152mm to 9am, providing the wettest recorded pair of May days since 1912.
Nearby, South Johnstone has endured wet season style rainfall with 256mm in the past two days, its wettest two-day total in 26 years.
Cairns has been picking up some much needed rainfall with its heaviest rain since January, gaining 72mm during the past two days. This month is the first since July to see above average rainfall, including a well below average wet season.
The heavy rain has been due to a semi-stationary low pressure trough on the North Tropical Coast. The slow moving nature of the trough has meant that rain has focussed on a similar area for the past two days.
The trough is weakening today and will allow showers to ease tonight. Showers will strengthen again on Friday, however falls should be lighter than recent days for most locations. The trough will then leave, allowing showers to ease significantly over the weekend.
