Minor flooding to put low lying areas of CBD at risk
UPDATE 4.55pm: Motorists and business owners in low lying areas of the CBD are advised to be aware of the risk of flash flooding overnight as the Wilsons River rises and the council close levee gates this evening.
Carparks on the riverside of the levee have already been closed.
The BOM is forecasting heavy rain overnight and the Wilsons River is predicted to reach the minor flood level of 4.2m later tonight and may reach 5m tomorrow, Lismore City Council's Local Emergency Management Officer Scott Turner said this afternoon.
"We will commence closing levee gates this evening and this means heavy rain falling directly in the Lismore basin could cause flash flooding in the CBD similar to what we experienced just before Christmas," he said.
Motorists are advised not to park their vehicles in low-lying areas around Dawson Street and Uralba Street and CBD businesses affected by the pre-Christmas flash flood are advised to be ready to move equipment, vehicles and stock to higher ground.
Residents are urged to monitor conditions and be prepared for potential flash flooding.
In life-threatening emergencies, call 000 (triple zero) immediately. If you require rescue, assistance to evacuate or other emergency help, ring NSW SES on 132 500.
Avoid drowning. Stay out of rising water, seek refuge in the highest available place.
Prevent damage to your vehicle. Move it under cover, away from areas likely to flood.
Avoid being swept away. Stay out of fast-flowing creeks and storm drains.
Never drive, ride or walk through flood water. Flood water can be deceptive and dangerous.
UPDATE 4.15pm: An initial flood warning has been issued for the Wilsons Rivers and other North Coast rivers are on flood watch.
The Wilsons River at Lismore is expected to exceed Minor Flood level of 4.20m on Monday night, and reach 5m on Tuesday afternoon.
The SES said communities in the Northern Rivers region are being asked to brace themselves for potential flooding this week.
Heavy rainfall has the potential to cause minor flooding from today through to the middle of the week throughout the Northern Rivers, with the Bureau of Meteorology issuing a flood watch for a number of local catchments.
Northern Rivers Zone Commander for the NSW SES, Chief Superintendent Steve Patterson, said the catchments to be affected by flooding are currently very wet following recent rainfall.
"This weather system is expected to cause flooding for the catchments listed from today and into the week," Chief Supt Patterson said.
River catchments expected to be affected are:
• Tweed and Rouse Rivers
• Wilsons River
• Richmond River
• Clarence River.
"This Flood Watch means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop," Chief Supt Patterson said.
"Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service."
Chief Supt Patterson said people who may be affected by the impending weather should take the time now to prepare their property for potential flooding.
"This includes moving stock to higher ground, moving pumps for creeks and rivers and having adequate resources on hand including food and water, should your property become isolated for a period of time," he added.
NSW Police and emergency services are reminding the community to take care as the wet weather continues to impact large parts of the state.
The Public Information and Inquiry Centre (PIIC) will continue to support the severe weather operation this week and can be contacted by calling 1800 227 228.
Members of the public can contact the PIIC for general information related to the severe weather and flooding. It will operate on a 24 hours basis until at least 5pm on Friday (March 26).
State Emergency Operations Controller, deputy commissioner Gary Worboys, has reminded the public to exercise caution as regions across the state were bracing for further rainfall and many river systems yet to reach their peak.
"Members of the public in the flood affected areas need to continue to heed the warnings and advice of the NSW State Emergency Service and all emergency services," Deputy Commissioner Worboys said.
"The message from Police and SES has been consistent for the last few days - if possible, avoid going outside and if you do drive, plan ahead - pay attention to RMS message boards for road closures or hazardous conditions, and never drive, ride or walk through floodwater.
"Do not put your life or that of emergency service personnel in danger," he said.
It should be noted the PIIC inquiry hotline is for general enquiries does not replace the State Emergency Service emergency hotline.
Members of the public seeking emergency assistance during a flood or storm should call the NSW State Emergency Service on 132 500, or visit their website www.ses.nsw.gov.au
For life threatening emergencies, the public are advised to contact Triple Zero.
UPDATE, 2.40pm: An initial Minor Flood Warning has been issued for the Wilsons River at Lismore.
The Bureau of Meteorology says minor flooding is expected from Monday night.
"Heavy rainfall since Saturday over the Lismore River catchment has caused river rises, and minor flooding is likely in the Wilsons River at Lismore from Monday night," the warning states.
"Further rainfall is possible over the coming days, and this may lead to further rises.
"The Wilsons River at Lismore (AHD) is below the minor flood level and rising.

"The river level may reach around 5m Tuesday afternoon."
UPDATE 12.25pm: A severe weather warning is in place for most of NSW today.
The Bureau of Meteorology said a strong high pressure system over the southern Tasman Sea continues to drive widespread and persistent rain onto the New South Wales coast. This is expected to continue today, particularly about the Mid North Coast and Northern Rivers.
On Tuesday, as the trough reaches the Tasman Sea, a low pressure system may form, bringing increased rainfall, strong winds, damaging surf and abnormally high tides to the east and south.
Most areas of New South Wales will see a clearing trend early Wednesday as a drier airmass moves into the region.
Heavy rain, likely leading to flash flooding, presents a serious risk to the Northern Rivers and Mid North Coast today and on Tuesday.
In some areas, heavy rain and flooding may be life-threatening.
A hazardous surf warning is also in place for the Byron Coast.
Roads in some areas are cut off by water, and there is an increased risk of landslips during this period. In addition, super-saturated soils along areas of the east bring an increased risk of moderately gusty winds toppling trees.
River catchments in this area are wet, bringing an enhanced risk of renewed riverine flooding. Numerous flood watches and warnings are current. Latest updates at http://www.bom.gov.au/nsw/warnings/.
Locations which may be affected include Lismore, Grafton, Coffs Harbour, Port Macquarie, Taree, Newcastle, Sydney, Wollongong, Nowra, Batemans Bay, Armidale, Orange, Canberra, Goulburn, Tamworth, Moree, Dubbo, Tibooburra, Cobar and Bourke.

UPDATE 10.40am: The Bureau of Meteorology said flooding is expected for much of the NSW coast today, including parts of the Northern Rivers.
On top of the existing Flood Warnings, rainfall associated with a deepening low pressure trough over western NSW has the potential to cause minor to major flooding over parts of the NSW East Coast and parts of the South West, Central West and North West.
A Severe Weather Warning is current.
Catchments likely to be affected by flooding are currently wet due to recent rainfall.
The weather system is expected to cause flooding for the catchments listed from Monday onwards.
Catchments likely to be affected include:
Tweed and Rouse Rivers - minor flooding
Wilsons River - minor flooding
Richmond River - minor flooding
Clarence River- minor to moderate flooding catchments.
Be aware heavier than expected rain can cause these flood levels to be exceeded.
Flood Safety Advice:
This Flood Watch means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop.
Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service.
Severe Weather Warnings will be issued or updated if very heavy rain is forecast or observed.
UPDATE 10.10am: As of 9.30am Monday, Ballina airport has most flights still scheduled to arrive from Sydney, Canberra, Melbourne and Dubbo.
Only one FlyPelican service from Newcastle has been cancelled today, as Newcastle's airport has been closed down due to flooding.
As of 6.10pm Sunday, 21 March, flights in and out of Newcastle Airport have been suspended, due to local flooding of the airfield.

• Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
• After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
• Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
• For emergency help in floods and storms, ring your local SES Unit on 132 500.
