Meteorological situation 
In the days between 19 and 23 February 1993, three surges of different intensity and 
duration were generated by stormy winds on the southern Baltic coasts. 
On 19 February, a depression over the Norwegian Sea travelled across Scandinavia and, at 
about 03-06 UTC, entered the Baltic Sea near Stockholm, where it remained nearly 
stationary for a while, filling and moving very slowly eastwards. After the passage of the cold 
front, at about 03 UTC, a SW - W offshore gale developed which covered the entire southern 
region of the Baltic Sea. Due to a high pressure ridge which developed over Scandinavia, the 
gale soon veered (about 15 UTC on 19 February) and increased to a N - NW storm over the 
entire Baltic Sea (00 UTC on 20 February). It was not until about noon on the same day that 
the wind backed and decreased to about 6-5 Bft in the area (Fig. 6.12.1.).
