Regional Airline Cancels Alaska Flights

Plumes of smoke, steam and ash from Pavlof continue to reach heights  of about 7,500m (24,000 feet),  according to Alaska Volcano Observatory (AVO).

Meantime, PenAir, a regional airline, canceled flights from Anchorage to  Cold Bay and Dutch Harbor on the Aleutian Islands on Wednesday.

Two strong explosions were recorded in seismic data early this morning (10:05 and 10:45 UTC; 02:05 and 02:45 AKDT) at Pavlof. Lightning was detected by the WWLLN system but there is no indication of higher altitude ash in satellite data. Meteorological cloud tops are up to 29,000 ft.

The eruption of Pavlof Volcano continues. Seismicity remains stable and unchanged in the past 24 hours. Persistent elevated surface temperatures were observed in satellite images. FAA web camera views yesterday afternoon showed a towering steam plume above the vent and lower-level ash from pyroclastic flow activity on the north flank. Wind direction has shifted in the past 24 hours to a more westerly direction and recent satellite views show a plume rich in SO2 gas, steam, and minor ash extending variably between 30 and 100 km downwind and passing over Cold Bay. There have been no reports of ash fall in Cold Bay or any other community. Incandescence from lava fountaining was visible in early morning web camera images, however low-level weather clouds obscure more recent views.

‘Humongous’ storm spreads across the US

Posted by feww on December 24, 2009

Christmas day could bring 2 ft of snow

Winter storm spreading from the north to Texas and from west Colorado to Illinois

“There’s just a humongous storm moving across the center of the country, basically from the Canadian border to Texas and spreading from west Colorado to Illinois.”  —National Weather Service.

At least 10 people have been killed most of them in accidents caused by icy roads throughout Kansas, Nebraska, and New Mexico. Up to 300 flights from Chicago airport have been canceled.

The latest storm closely follows a record snowfall that blanketed the US East Coast last weekend, causing power cuts to at least 100,000 customers in the region. Many in West Virginia and Virginia are still without power, reports said.

The storm system developed in the southwestern US on Tuesday creating large dust storms across the California desert and Arizona.

The system then moved across the country to the Midwest and is currently causing severe blizzards throughout the region covering a large area from Kansas to Minnesota.

“We would recommend that people if at all possible postpone their travel plans just to be on the safe side,” Pat Slattery, a spokesman for the National Weather Service said. “This is not a storm to be messed with.”

Nebraska, and the Upper Mississippi Valley should experience the worst of the snow accumulation, with freezing rain expected across much of Illinois, Indiana, Iowa, Kansas and Nebraska, forecasters said, warning of thunderstorms causing flooding across the Ohio Valley to Texas in the south.
