Commencing 10 October 2011, the Warnings and Signals Database would also display the provisional records
of recent warnings/signals in addition to the official records.  Provisional records will normally be checked
during the first working day after the expiry or cancellation of the warning/signal for confirmation to be
accepted as official records.
