NOAA has altered its predicted path of Hurricane Frances several times over recent days.
Huge advances in hurricane prediction have been made in the years since Hurricane Andrew.

He reports on the latest developments in hurricane science and technology - and why it's still proving so difficult to predict the intensity of the storm.
