Planes are being warned to avoid airspace near an erupting Alaska volcano as it spews ash 30,000ft above sea level. The National Weather Service said on Saturday ash was being blown to the west and northwest of Pavlof Volcano. Pavlof began erupting three days ago, pushing lava out from a vent near its summit. On Friday, the ash cloud reached 16,000ft. Alaska Volcano Observatory geophysicist Dave Schneider said the eruption intensified at 6am on Saturday, sending the ash cloud higher. Schneider said it was not clear how long the eruption will last, as Pavlof's eruptions may last for weeks or months with varying levels of intensity. Pavlof is Alaska's most active volcano. It sits along international air routes connecting Europe, North America and Asia.

An apparent tornado touched down early Monday at a state prison near Blountstown in Florida's panhandle, slightly injuring two people and damaging a number of vehicles. Workers were just arriving for their shifts early Monday at the Calhoun correctional institution and hadn't even got out of their vehicles when the storm struck around 4am CST. There was 'major damage' to between 25 and 30 vehicles in the parking lot and some of the fencing around the prison's perimeter was knocked down. No one escaped from the facility, which has a maximum capacity of 1,354 inmates.

The last storm in a series of four brought another 25-75 mm to parts of northern Italy on Monday, with just some lingering showers on Tuesday. So far this month, rainfall has exceeded 250 mm in many areas from southeast France into northern Italy and southern Switzerland. Already over 600 mm has fallen in Genoa, Italy, and 420 mm has soaked Nice, France. In Genoa, this is almost half of the yearly average rainfall in just two weeks.
19th
A round of strong thunderstorms lashed the Brisbane (Australia) area with torrential rainfall and gusty winds. The storms caused flash flooding and knocked out electricity in parts of the region. The city and surrounding areas were struck during the middle to late afternoon when thunderstorms developed to the south and blasted northward. Rainfall of more than 50 mm fell in 30 to 60 minutes resulting in flash flooding as many road ways were left impassable.

Between 3 and 6 feet of snow and plunging temperatures have left thousands snowed in over upstate New York, and the cold and snow has taken lives. Four people died Tuesday due to the heavy snow. Three of the incidents were caused by cardiac arrest from shovelling snow, while the other one was due to an automobile accident. There were two additional deaths on Wednesday, bringing the death toll to six. Another two deaths were reported on Wednesday evening. A large lake-effect snow band formed on Monday night over Lake Erie as cold arctic air began sweeping over the relatively warmer Great Lakes. The snow band took aim at western New York and lingered for nearly 24 hours. Communities along the I-90 corridor in southwestern New York, from Silver Creek to the towns south of Buffalo, have been left in a disabled state, after several feet of snow fell on Tuesday. Parts of New York measured the season's first big snowfall in feet, rather than inches. Parts of western and northern New York state average more than 100 inches of snow during the winter season. The lake-effect snow this week represents a large amount of the seasonal average. Depending on the investigation of snowfall measurement activities, there is a chance the 24-hour United States snowfall record could fall. That official record belongs to Silver Lake, Colorado, with 76 inches, spanning April 14-15, 1921.
