A fire that started in a Revesby car wrecking yard on Saturday morning is almost contained, with one person suffering burns and two people with smoke inhalation, according to NSW Fire and Rescue. One hundred firefighters and 20 fire trucks have been battling to prevent the fire from spreading to nearby houses. Warm, windy and clear weather has assisted a series of fires across Sydney with emergency services currently responding to blazes in Castle Cove, Mulgrave, Llandilo, Revesby and Terrey Hills. NSW Fire and Rescue Superintendent Adam Dewberry said the Revesby car yard on Mavis Street is "well-alight" and that winds are pushing the blaze into residential streets. Homes on Jellicoe Street and Gallipoli Street have been evacuated. Bankstown-Lidcombe Hospital is on standby to evacuate if the fire reaches adjoining buildings. At least two of the injured men were taken to hospital, one treated for minor burns and the another man treated for smoke inhalation. Eastbound traffic on Canterbury Road is being diverted onto The River Road, police are advising road users to avoid the area. Emergency Services received multiple calls reporting the fire, with billowing smoke visible from neighbouring suburbs. A fire has also lit in a reserve in Castle Cove on the lower North Shore posing a potential threat to nearby houses on Deepwater Road. While the fire has been contained, 10 homes have been evacuated in the surrounding area. The Rural Fire Service has issued a watch and act warning for residents in the area, suggesting they begin to take action to protect themselves and family members. The first fire ban in NSW for the season has been in effect on the Far North Coast since this morning, in response to forecasts predicting warm weather and northwesterly winds of up to 60 kilometres per hour. A southerly change moving up the coast is expected to cool temperatures later tonight. Rural Fire Services has listed the greater Sydney region as a 'very high' fire danger zone. The past 36-hours have delivered a sobering portent of the fire risk in in coming summer months. On Friday a bushfire in Llandilo and Cranbrook burned ferociously for four hours, causing police officers to evacuate homes, two schools and a nursing home. The Rural Fire Service reported damage to a number of properties on streets bordering the fire. Eventually, 200 firefighters from the Rural Fire Service and Fire and Rescue NSW were able to get the blaze under control at 6pm. On Saturday a 16-year-old boy was arrested at Penrith Railway Station and later charged with intentionally causing a fire and recklessness. Less than five kilometres away from the Llandilo fire, 2000 bails of hay are alight at a farm supplies property in Mulgrave. Superintendent Adam Dewberry said the cause of the fire was not yet known. "With extreme fires it is possible for spotting to occur that far ahead. However, due to exothermic reactions within hay bails, they are also known to spontaneously ignite," Mr Dewberry said. The fire is encroaching on the T1 Western railway line to Richmond. As track work is occurring on this line over the weekend the fire has not impacted existing public transport arrangements. Currently, fire crews are using a remotely operated fire fighting engine to pull apart the burning bails of hay and soak them in foam and water. Due to further forecasts of warm and windy weather, Mr Dewberry said he expects fire crews will be present at the Mulgrave fire for the next few days. "It will be very smoky," he said. Mohammed Nabi of the Bureau of Meteorology said rain is not expected in Sydney until Wednesday. "Currently there are winds southwesterly winds in Sydney of 30 to 45 kilometres per hour and there will be clear conditions until the evening. Wednesday is the next day showers are expected to come through," Mr Nabi said. A 490 hectare fire that started yesterday continues to burn at Callala Bay near Jervis Bay. A number of bushfires have sparked in to the Hunter Region threatening road access and property. Inspector Ben Shepherd of the Rural Fire Service said an out of control bushfire on Racecourse Road is expected to cross the railway line. Property protection action is underway. Another out of control bushfire north of Raymond Terrace, originating on Lone Pine Road, is expected to cross the Pacific Highway.
