ICE CONDITION FORECAST 09.02.-18.02.2006.
Within the next 10-day the frost over the Baltic Sea region will weak and the ice formation
will slow down.
At the beginning of the period the moderate south-east wind will cause the ice drifting to
north-west. This will increase the amount of the ice in the north part of the Gulf.
On the fairway Riga-Irbes strait in the region of Kolka the accumulation of compact ridged
drift ice is possible. In the south part of the Gulf the new ice formation will slowly continue.
The fast ice will remain locally along the coast of the Gulf of Riga.
In the second half of the period due to the west, south-west wind the mild Atlantic air will
penetrate to the region of the Baltic Sea. The new ice formation will be interrupted. The ice will
drift eastwards.
