BERLIN, May 24, 2011 (AFP) - Volcanic ash from Iceland is expected to reach Germany's North Sea coast on Tuesday evening, forecasters here said, citing information from the Volcanic Ash Advisory Centre at Britain's Met Office.

"We have been informed that there will be concentrations of ash of between 0.2 and 2.0 milligrams in northern areas this evening or tonight," meteorologist Marcus Beyer from the German Weather Service (DWD) told AFP.

The country's ADV airports association said it could not yet give an estimate on how many flights might be cancelled as a result.

"We cannot rule out that the northern part of Germany will be affected. We will have to wait and see," ADV spokeswoman Bruni Schubert told AFP.

German flag carrier Lufthansa said that so far it has cancelled just two flights from Germany to Edinburgh.
