Noon GMT Some more pictures overnight – a selection of clips from a short HuffPo video
22.00 GMT Latest news: Hurricane Isaac has just been downgraded to a Tropical Storm (I realise that for those caught up in the heart of flooding, damage and widespread outages, this may be of little practical comfort – but it is perhaps some encouragement for those further north in the path of the storm).
18.00 GMT Some pictures are now coming out giving an idea of the ferocity of the storm. I’ve assembled a short gallery from Reuters, AP/Getty and similar news resources, which I will add to as and when…
Noon GMT The latest Wunderground tracker map for Hurricane Isaac shows the storm’s current position and its subsequent path, decreasing to tropical storm and then tropical depression as it sweeps northwards through Arkansas. The eastwards tendency, noted previously, is now pronounced with the storm predicted to turn towards Missouri and Kentucky.
09.00 GMT Having had many hundreds of hits for this storm post, including a great many from the southern coastal states of the US, I am posting some further information about Hurricane Isaac today, as the storm rages over New Orleans and more widely across the state.
I have been wondering about the New Orleans flood defences that are constantly referred to in news reports, so firstly here is a clear map of the situation showing the reinforcement since Hurricane Katrina
Here is a satellite video of Hurricane Isaac approaching the US coast, taken over two days. It vividly shows the development in the Gulf of Mexico from a “disorganised” tropical storm into a swirling, concentrated hurricane-force storm, with the eye becoming visible as it approaches the coast.
Finally (for now) this is the astonishing view from a space station, giving an idea of the storm’s extent

TS ISAAC STORM TRACKING: LATEST UPDATE 09.00 GMT
Here is this morning’s (GMT) tracking map, with the storm in the Gulf of Mexico, still drifting westwards. Predicted landfall is now mainly on the Louisiana coast. The most significant change overnight is that the Cat 2 prediction has been downgraded, so that the max expected strength is Cat 1
The satellite picture shows Isaac thickly covering the Gulf of Mexico with dense cloud. The coloured markings to the right show the data recorded by the NOAA Hurricane Hunter flying on the eastern edge of the storm (where the winds are less)
Since this is a Bahamian-based blog (with close Florida connections) Isaac’s current position makes this a suitable moment to return to the main business of Rolling Harbour – the wildlife of Abaco. At exactly this time last year, Hurricane Irene was passing directly over Abaco, with the eye going right over HQ at the Delphi Club. The northward passage of Isaac has of course affected the weather there, but it has been spared the ferocity of 2011. We’ll be thinking of course about all those in the US in Isaac’s path when landfall is made shortly
I have concentrated for obvious reasons on the projected path of Isaac with special reference to its proximity to the Bahamas in general, and Abaco in particular. I may have given the impression that the continuing westward movement of the storm’s path has meant that Abaco would enjoy glorious dawns, wonderful sunny days and spectacular sunsets. Not so, of course – the side-effects of the storm continue laterally for large distances. It’s lunchtime on Abaco now, and a message from Brigitte Carey on Tilloo Cay says simply “Yes, its nasty here – lots of wind and rain!”

First, a recent satellite image of the developing Cat 1 hurricane, still expected to reach Cat 2 as it make landfall on the southern US coast, followed by a tracker map confirming the westward tendency of the predicted path Continue reading
