`Massive` ash cloud closing western Irish airports

Iceland`s volcano has produced a 1,000-mile-wide ash cloud off the west coast of Ireland.

Dublin: Iceland`s volcano has produced a 1,000-mile-wide (1,600 kilometre-wide) ash cloud off the west coast of Ireland that will force western Irish airports to shut down again on Friday, the Irish Aviation Authority announced.

The authority said shifting winds, currently coming from the north, had bundled recent days` erupted ash into a massive cloud that is growing both in width and height by the hour.

Eurocontrol, which determines the air routes that airliners can use in and around Europe, says the ash accumulation is posing a new navigational obstacle — because the cloud is gradually climbing to 35,000 feet (10,500 meters) and into the typical cruising altitude of trans-Atlantic aircraft. Until recent days, the ash had remained below 20,000 feet (6,000 meters).

The Irish Aviation Authority said the engine-wrecking ash would skirt Ireland`s western shores Friday, forcing a half-dozen airports to ground flights for much of the day. However, the airports in Dublin, Cork in the southwest and Waterford in the southeast will remain open.

"The restrictions are required as the increased level of recent volcanic activity has created a massive ash cloud stretching 1,000 miles long and 700 miles wide," the authority said in a statement.

The latest alert came only hours after British and Irish authorities declared the all-clear after much of the same ash was blown southwest from Scotland through Ireland on Tuesday and Wednesday, closing airports all along the way. Those were the first European air closures since the initial April 14-20 crisis, when ash from Iceland`s Eyjafjallajokul volcano forced authorities across Europe to ground 100,000 flights and 10 million passengers.

Britain`s Meteorological Office said that, given the direction of the winds, "the risk of the ash cloud affecting UK airspace in the next couple of days remains low."

Eurocontrol, the continent`s air traffic management agency in Brussels, also announced on Thursday it plans to reroute flights between Europe and North America to avoid flying over the ash cloud off Ireland`s west coast.
