As forecast by the Bureau of Meteorology, Tropical Cyclone Alfred was downgraded to a category one system on Sunday, but as of Monday morning, it has strengthened back to a Category 2 system.

John How from The Bureau said they are seeing winds near the centre of 95 km/h and wind gusts up to 130 km/h.

"As of Monday morning, it is currently a category two system over the Coral Sea, about 465 kilometers northeast of Brisbane and 410 kilometers northeast of Maroochydore on the Sunshine Coast. It is moving in a south-easterly direction at around 13 kilometers an hour, sort of about a running pace, moving down towards the south-east."

As we know, there are a number of warnings for both South East Queensland and North East New South Wales already in place.

"So first, we do have marine wind warnings all the way from K'gari down through the Sunshine Coast off Brisbane, the Gold Coast and the Northern Rivers of New South Wales. That's for strong to gale force winds, and we'll see those strong winds extending down to even the mid north coast of New South Wales over the next few days.

"There is also a coastal hazard warning for parts of the Queensland coast. That is for very powerful waves, which you have been seeing over the weekend, as well as normally high tides. And the combination of very powerful waves and these high tides does mean that we are already seeing beach erosion across southern parts of Queensland. Those high tide peaks will gradually start to recede from today, but those strong waves coming in from the east will persist for several days as Tropical Cyclone Alfred sits off the coast of Queensland.

"Other warnings. We do also have a hazardous surf warning for parts of the south east, Queensland coast and North East New South Wales. That does mean that if you are heading out to the water, this will be dangerous for activities like swimming, boating and also rock fishing. In addition to this, the Bureau has also issued an initial flood watch for both Queensland and New South Wales.

"For Queensland, it does include quite a few catchments across the south east of the state, this is a heads up for heavy rainfall, increasing from late Wednesday, continuing into Thursday and Friday. Catchments across South East Queensland are dry to moderately wet, and as well as that normally high tide coming through, it does increase the risk of flooding for those coastal low lying areas, but once the rainfall does pick up, we could see widespread, minor to major flooding across the Queensland FLOOD WATCH area from late Tuesday, late Wednesday and also into Thursday, but the location of the highest rainfall will determine where we do see that flooding.

"We also have an initial flood watch for the Northern Rivers and also the mid north coast. This is also for the potential of up to major riverine flooding as you start to see that rainfall coming through late Wednesday into Thursday, and also Friday. So across both these areas, we are reminding residents to keep across the latest warnings and also flood watches as well, and later on Monday, we are expected to issue the first tropical cyclone watch that's for the onset of gales across mainland areas likely to be on onset from sort of Wednesday and into Thursday as well. So quite a few warnings, and we are expecting more warnings to be issued over the coming days."

Jonathon said Alfred is expected to continue to move towards the southeast today and may be downgraded to a Category 1 but then is still expected to move back towards the west towards southeast Queensland coast as a Category 2 system.

The forecast path of Tropical Cyclone Alfred, shown above, is the Bureau's best estimate of the cyclone's future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.
