. This ( and of coarse the high tide) had some effect on the strength of the flood, but not such a great one and the flood was mainly caused by the reason above. Sturmflut-Hamburg

On Thursday 15 February, German authorities published the first storm warning for the North Sea with wind speeds up to 9 Beaufort. A severe storm warning followed the next day, with a predicted gauge of 3 metres above normal, which was a level the dykes could withstand. The severe storm and the flood it caused in the last hours of 16 February affected the dykes more than predicted and led to some 50 breaches before officials raised the alarm for Hamburg. At this time of the day, most city offices were closed, which slowed the notification of the population. Civil protection plans were not implemented yet. Hamburg Sturmflut 023

Due to telephone landline breakdowns, warnings could not be forwarded from coastal to inland emergency offices. Breakdowns in alarm siren lines and electricity lines severely affected the warning system. Radio amateurs had to establish emergency operations to support emergency services as a means of communication. Around midnight, the peaks were too high for some dykes to withstand. The backs of the dykes were not fortified, so the first overtopping waters destroyed the dykes from behind and cleared the way for the flood.
