Don't take it too literally keensailor, a High or Low is a relative term and simply means an area of pressure higher or lower than the surrounding area. So strictly speaking, there may be an area of pressure surrounded by lower pressure, but that does not mean the general characteristics of a high pressure system will be found in that area. Take a look at this, a few hours after yours, but you can see the characteristics of two low pressure areas now a further east from your chart.
The BOM chart shows two lows
Earthwindmap is a really good way to look at the relationship between synoptic charts and winds. But, when you get up to the tropics, you are better looking at Gradiant Level Wind Analysis charts as air pressure gradients are more spread out and don't give the best indication of wind, unless really intense like for cyclones.
