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.

The previous deadliest weather disaster this year was the snow avalanche in Afghanistan that killed 172 people on February 8 and 9.

Is that a mid-level circulation? I know the Atlantic Ocean is plenty warm, however, yesterday many said wind shear was very high in that area.

Cloudy with a little patchy rain about the western and northern Plateau increasing in intensity early tomorrow and extending throughout for a period before contracting to the west again during the afternoon, briefly falling as snow about the highest peaks during the afternoon and evening. Cool to mild with light to moderate northwest winds ahead of a colder west to southwest change tomorrow.

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!!

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.
