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.

NB: Records shown in blue background and Italic font are provisional information for reference only.
