Airports in Ireland and parts of Britain were closed again for some hours on Tuesday because of the cloud of volcanic ash drifting south from Iceland that wreaked havoc on European air travel last month.

Flights in much of continental Europe were operating as normal and the Irish Aviation Authority (IAA) said it would allow flights to resume from Irish airports from 1200 GMT after a closure lasting six hours.

However, the IAA said northerly winds forecast for the coming days could bring more clouds of ash from the Icelandic eruption and disruption for passengers this week.

“We could be faced with this periodically during the summer,” IAA Chief Executive Eamonn Brennan said. “We are probably facing a summer of uncertainty due to this ash cloud,” Brennan said.

The IAA had closed airports from 0600 GMT until 1200 GMT due to risk of ash ingestion in aircraft engines, although overflights of Ireland from Britain and continental Europe had not been banned.

The UK’s National Air Traffic Services (NATS) said a no-fly zone was in place in the west of Scotland and Northern Ireland, from 0700 a.m. (0600 GMT) until at least 1300 (1200 GMT).

European flights overall were expected to be at almost normal levels on Tuesday, European air traffic agency Eurocontrol said.

On a typical weekday, just under 200 flights would be expected in and out of Ireland, compared with around 28,000 throughout Europe, a spokeswoman said.

Ash particles from Iceland’s still-erupting volcano remain high in the atmosphere and do not pose a health risk so far to people in Europe, the World Health Organization said on Tuesday.

Toning down its guidance from Friday, when it said the ash cloud that has grounded flights could be “very dangerous” for those with asthma and respiratory problems, the WHO said there was no cause for public health alarm so far.

“There are no effects on health at the moment, except in the vicinity of the volcano in Iceland,” Carlos Dora of the public health and environment division told a news briefing.

Icelanders living near the volcano should stay indoors or wear face masks and goggles to protect themselves against coarse particles that can irritate the lungs and eyes, Dora said.

The most dangerous ash particles are the smallest ones which can be breathed in deep into the lungs, and which have moved further from the volcano in the plume billowing over Europe.

But those fine particles are still “very high up” and weather conditions could very well cause the ash cloud to disperse without causing health problems in Europe, Dora said.

The World Meteorological Organization, based in Geneva, like the WHO is based in Geneva, said the ash particles were made up of small jagged pieces of rock, mineral and volcanic glass the size of sand, salt or silt. Such fine particles are normally dispersed by thunderstorms which are not expected in the region in the coming days.

A low pressure weather system is expected to develop over Iceland later this week, potentially pushing the cloud toward the Arctic and prompting rain to “wash out” the ash, the WMO said in a statement. A WMO expert said that the health risks of the cloud were currently negligible across Europe.

Iceland Volcano Sends New Tremors, Lower Ash Cloud

The erupting volcano in Iceland sent new tremors on Monday, but the ash plume which has caused air traffic chaos across Europe has dropped to a height of about 2 km (1.2 miles), the Meteorological Office said.

Visibility near the Eyjafjallajokull glacier was almost nil as falling ash saturated the air and covered agricultural fields with a thin layer of dust which could be dangerous to animals if eaten, local media quoted the police as saying.

There was a risk, however, that molten rock could create new pathways for water to run into the crater, causing more explosions and a higher level of ash production.

The ash plume, which has cost airlines millions of dollars per day in lost revenue, had descended to a lower altitude as strong winds continued to push the cloud southward.

The ash plume is very low. It’s not much higher than 2 kilometers. The column of ash rising from the volcano was as high as 11 km when it started erupting earlier last week.

Air traffic over Europe remained severely disrupted on Monday.

Europe’s air travel chaos deepened on Saturday as a huge cloud of volcanic ash spread southeast across the continent, halting more than three in four flights and stranding tens of thousands of passengers worldwide.

European aviation agency Eurocontrol said no landings or takeoffs were possible for civilian aircraft in most of northern and central Europe because of the ash spewed out by the Icelandic volcano, which was still erupting.

Many countries closed airspace until Sunday or Monday and weather experts forecast the cloud would not move far. They said the plume of ash could even become more concentrated on Tuesday and Wednesday, posing a greater threat to air travel.

The plume that floated through the upper atmosphere, where it could wreak havoc on jet engines and airframes, is costing airlines more than $200 million a day.

A plume of ash has spread across northern Europe from a volcano beneath the Eyjafjallajoekull glacier in southern Iceland. Icelandic media report that the eruption is continuing, but there have been no earth tremors since Thursday evening.

Volcanic ash has fallen in parts of eastern Iceland and there are fears that ash could spread to Reykjavik if the wind direction changes.

There are fears of an even bigger eruption if the vulcanism sets off the nearby Katla Volcano, which is also covered in ice.

Air traffic has been severely disrupted across northern Europe by the volcanic ash, seen stretching from Iceland (upper left corner) to Western Europe (right) in the main image.

Airspace has been closed or flights cancelled in countries including the UK, the Republic of Ireland, Denmark, Norway, Sweden, Finland and France.

All flights in and out of the UK and several other European countries have been suspended as ash from a volcanic eruption in Iceland moves south. Two of the detail images show the ash veiling the skies over Western Europe, while another provides a map of the spreading of the ash.

In addition, the eruption has caused parts of the glacier to break up and melt, causing flooding in areas around the erupting volcano and prompting the second evacuation of local people in 48 hours. The level of the glacial Markarfljot river – swollen with ice and mud – has also risen. The flooding has cut off the coast road from the area to the capital Reykjavik and threatens isolated farms.
