Flood spotters working along from Hull's docks to city centre
Spotters looking out for a flood threat are being posted along the banks of the Humber.
They will operate over the weekend and on Monday at points from the port's docks to the city centre.
In December tides and winds caused a storm surge, flooding parts of northern Lincolnshire and East Yorkshire.
Spurn Point peninsula, a Yorkshire Wildlife Trust (YWT) reserve, was closed after being hit by the North Sea tidal surge.
A spokeswoman for Hull Council said crews were stand-by with sandbags "in the unlikely event that they are needed".
