California's calm before the storm. It's just rain, right? Well, the meteorologists are publicly talking about a potentially epic storm that could trigger major flooding and mudslides, especially in areas effected by the state's widespread fires of the past few years. More ominously, though, is this internal email from CAL FIRE Division Chief Bob Wallen, which talks of the potential for "multiple large and powerful storm systems" with "a tremendous amount of precipitation . . . Much of NorCal is likely to see 5-10 inches in the lowlands, with 10-20 inches in orographically-favored areas. Most of SoCal will see 3-6 inches at lower elevations, with perhaps triple that amount in favored areas", with the potential for a massive snowfall, gusts in the 100-200 mph range in the high Sierras, possibly followed by plentiful warm rains that could melt the snow and cause massive flooding statewide. "The next 2-3 weeks (at least) are likely to be more active across California than any other 2-3 week period in recent memory."

Pull out a US $20 bill. Take a look at the picture of the White House. See that tree peeking in from the right, the 140 year old elm that's been there since Andrew Johnson? Well, it's gone. Yup. Fallen over, thanks to the soaker summer storms which have been hammering the Mid-Atlantic in recent days. Cleanup has started, but no word on whether the $20 bill will be needing another update.

Tuesday, July 26th, 2005, was a wet day for the city of Mumbai, India (formerly Bombay), to say the least. Within 12 hours, it rained more than half the average annual rainfall. Upwards of 400 people are believed to have died, with more in adjacent regions. In many regions, the water rose as high as five feet. All transportation links to the rest of India were severed. Within the city, many commuters who left work, for home, on Tuesday evening, didn't reach home till Wednesday night. There have been substantial financial and ecological damages. The state apparatus was caught offguard and proven unprepared; the police were nowhere to be found, and the meteorological department found wanting with their warnings. The rumour-mongering of an incoming tsunami or cyclone also didn't help, as 24 people died in the resulting stampede. Alas, just as one is relieved that the ordeal is over, it appears there's yet more to come.
