PROGNOS

18-23 mars 2003

Högtrycket vid Skottland förskjuts sakta till

södra Östersjön. På onsdag-torsdag utbreder

sig kalla nordvindar över Bottniska viken och

Östersjön. De följs av en högtrycksrygg, som

passerar åt sydost över Skandinavien på

torsdag. I slutet av veckan rör sig ett djupt
lågtryck österut över Ishavet varvid milda

sydvästvindar utbreder sig över Skandinavien.

Medeltemperaturen för perioden blir över den

normala i de svenska farvattnen med tillfälligt

kallare väder på torsdag. Det betyder

medeltemperatur mellan –9 och +2 grader på

Bottenviken och Norra Kvarken, mellan –5
och +3 grader på Bottenhavet, Ålands Hav,

Östersjön och Mälaren. Plusgrader i övriga

svenska farvatten.

Isen på Bottniska Viken väntas under tisdagen

driva nordost- eller ostvart och råken längs

svenska kusten fortsätter att vidgas. Dock kan

isen tillfälligt packas syd om Nordvalen.
Senare under onsdagen och på torsdag väntas

sydlig isdrift. En råk kan öppnas i norra

Bottenviken medan isen packas samman

utanför Bjuröklubb och möjligen ned mot

Holmöarna. Även på Norra Kvarken och

nordligaste Bottenhavet väntas isen driva

sydvart och nya breda råkar bildas i området

Nordvalen-Väktaren-Sydostbrotten. Snabb
nyisbildning väntas på råkarna. Den redan

spridda drivisen på norra Östersjön bryts upp

alltmer och skingras. På Vänern väntas

efterhand långsam isavsmältning.

FORECAST

18-23 March 2003

The high pressure near Scotland slowly will

move to southern Baltic. On Wednesday-

Thursday cold northerly winds will penetrate

the Bothnian bay and the Baltic followed by a
high pressure ridge on Thursday. Later this

week a deep low will move eastward on the

Ice sea and mils southwesterly winds spread

over the Scandinavian waters.

The mean temperature for the period will be

above the normal, but shortly interrupted by

cold weather on Thursday. This means mean
temperatures between –9and +2 degrees C

on the Bay of Bothnia and the Quark,

between –5 and +3 degrees C on Sea of

Bothnia, Sea of Aland, the Baltic and lake

Malaren. Remaining waters above zero.

The ice on the Bothnian Bay during Tuesday

wilkl be adrift northeast- or eastward and the
lead along the Swedish coast widen. Shortly

the ice may press south Nordvalen. Later on

Wednesday and on Thursday southerly ice

drift. A lead may open in the northern Bay of

Bothnia, but press off Bjuroklubb and

possibly towards Holmoarna. Also on the

Quark and northernmost Sea of Bothnia the

ice will be adrift southward and new wide
leads open in the area Nordvalen-Vaktaren-

Sydostbrotten. Rapid new ice formation in the

leads. The open drift ice on northern Baltic

will break up and dissolve.

On Lake Vanern slowly ice melting.
