The Port of London Authority Launches New Ebb Tide Flag Warning System13 February 2014
The Port of London Authority (PLA) has launched a new web-based safety indicator system, the ‘Ebb Tide Flag Warning’ system, which alerts rowers, canoeists, and other small recreational vessels of conditions on the tidal River Thames. This system is mainly for when the ebb tide and fluvial flows combine to make river conditions perilous, much as they are at present after sustained periods of heavy rain and flooding.
The warning system is designed to inform users of the tidal Thames of potentially dangerous conditions. The appropriate flag for the ebb tide will be posted on the PLA website. A red flag indicates that PLA urges extreme caution and advises that man-powered vessels do not go afloat. A yellow flag indicates that PLA advises against navigation of the tidal Thames by those who have little experience on the tidal section of the river, including schools, novices and junior crews.
