World's deadliest weather disaster of 2010: Rio de Janeiro floods kill at least 183

By: Dr. Jeff Masters, 5:06 PM GMT on April 09, 2010

The world's deadliest and most expensive weather disaster so far this year hit Brazil this week, where at least 183 people are dead due to flooding and mudslides in the Rio de Janeiro region. Damage from the flooding has been estimated at 23.76 billion reais (US$13.3bn, €9.9bn), about 8% of the gross domestic product (GDP) of Rio de Janeiro State. Rio's heavy rains began near 5 pm local time (2000 UTC) on Monday April 5, and continued for 24 hours, with a total of 28.8 cm (11.5") of rain falling--more than the average rainfall for the entire month of April. It was the heaviest rainfall ever recorded in Brazil's 2nd largest city. The rains triggered devastating mudslides that roared through slums built on steep, unstable hillsides. According to the Associated Press, crews have pulled 17 bodies from the debris so far at at a new mudslide that hit in Niteroi, next to Rio, on April 7. Authorities fear an additional 150 people may have died there.

Mission Control has determined that an earlier window may exist and that the launch might begin sooner than scheduled.

If he would just contribute...taht's really all he has to do, and people would ease up on him.

Unfortunately, he's one of those people who sticks to an obnoxious style that antagonizes others.

Polish leader, 96 others dead in Russia jet crash


SMOLENSK, Russia

Polish President Lech Kaczynski and some of the country's highest military and civilian leaders died on Saturday when the presidential plane crashed as it came in for a landing in thick fog in western Russia, killing 97, officials said.

Russian and Polish officials said there were no survivors on the 26-year-old Tupolev, which was taking the president, his wife and staff to events marking the 70th anniversary of the massacre in Katyn forest of thousands of Polish officers by Soviet secret police.

What a way to usher in early fall in Australia! After record breaking heat, dust-storms, severe thunderstorms and a handful of tropical cyclones, now snow!!
