Communities in Queensland are being warned to be prepared for high rain and flooding as ex cyclone Koji heads inland, while emergency services are warning of dangers from flooding, although destructive winds are easing.
Heavy rainfall is still forecast for much of the state as the remnants of convective system Koji move across Queensland with the possibility of flash flooding and river level rises as a result of the extreme weather impacting already full river basins.
The system weakened after making landfall however, according to forecasts the fact that the cyclone strength has diminished does not lessen the danger of heavy rainfall.
The moisture that was associated with the former tropical system is predicted to move inland and towards the southern regions.
Emergency officials reported that the biggest threat has now changed from high winds to water effects, especially in flood zones and river and creek side neighborhoods.
Residents were advised to keep a very close eye on the situation and to avoid traveling and particularly at night when floodwaters are difficult to spot.
In an effort to protect their communities local councils in regions of northern and central Queensland have started closing flood prone roads, while some schools and other services also changed their operations.
Power outages reported due to the system impact along the coastline were being restored but more outages may occur if the rainfall continues.
In a statement issued by the Bureau of Meteorology it was expected that the rain bands would move slowly and produce intense rain in a short while, posing the threat of flash flooding in urban areas.
In catchments where high water levels are being carried the rain may cause quick responses, posing the threat of moderate or major river flooding in some areas.
Even as the total rainfall amounts are in question there are recommendations that people should not rely on one amount of rainfall.
There may be variances in rainfall, especially in cases of decomposing tropical cyclones that are in close proximity to weather in inland areas.
“Disaster management arrangements are currently in operation in several areas in Queensland,” with state emergency officials organizing support for local councils there.
Swift water rescue teams and extra emergency crews are on standby in case conditions worsen.
Rainfall brings a mix of implications for farmers. While soaking rain will provide welcome relief after a dry start to the season in some areas, it risks crop damage, stock losses and delays to the planting and harvesting of crops in others, particularly where paddocks are waterlogged.
Meanwhile, insurers have urged residents to document any damage and take reasonable steps to protect property where it is safe to do so.
Past flood events have demonstrated that even ex cyclones can deliver widespread losses well inland, long after the initial coastal crossing.
State leaders said the coming days would be critical and underlined complacency is a major risk once a system is downgraded.
They urged Queenslanders to follow official warnings check on neighbours where possible and never drive through floodwaters.
Forecasters said the remnants of ex cyclone Koji should weaken further as the system moves south and east, though rain may linger in some districts before conditions improve gradually.
Authorities said the situation remained dynamic with communities advised to stay informed through official channels as the system continued to cross the state.
