Mr Carson said the Bureau of Meteorology worked so closely with emergency services during times of environmental crisis that the two couldn't work without each other.

Widespread rainfall this week has meant the two organisations have had to work more closely than usual.

Mr Carson, who has been working at the bureau for 14 years, was at work at 3.30am yesterday preparing for floods, heavy rain and thunderstorms in the region.

''Emergency services take our advice based on the weather information and flood warnings that we give them,'' Mr Carson said.

''They have to make the call on evacuations based on our information.

''We can't work without each other.''

In the early part of Mr Carson's career, his time was spent dealing with drought and top temperatures.

It has only been during the latter part of his career that he has learnt more about flooding and heavy rain.

''Prior to last year, 80 per cent of my career was focused on drought and bushfires,'' he said.

''Whereas the last two years it's been all about rainfall, so I'm learning more about river flooding, rainfall intensities and giving critical information to emergency services.''

Interviews with media organisations take up a large part of the Canberra bureau's day.

During disasters, people want to know about records, Mr Carson said.

''There is a tendency to get really excited in this job when you see something big happening and some people tend to sensationalise it and push the boundaries too far.''
