It would be a dangerous option to rely entirely on digital electronics for Canvey’s flood early warning.

Unless the old sirens are kept, there would be no manual back up system in the event of widespread disruption to electronic communications at the same time as a dire emergency.

This may be unlikely, but in view of the seriousness of potential flooding, or other catastrophic event affecting the area, this scenario should be considered.

With recent warnings of impending potential massive sun-spot activity, even this could render communications and/or electronic equipment ineffective.

In my view every potential hazard needs to be taken into account, however rare.

The sirens could well be the island’s life insurance.
