Do you live in a flood plain? You may be (unpleasantly) surprised the next time you catch up with your insurance agent.
Many residents of Toronto didn't think they lived in a flood zone, either. Monday evening two month's worth of rain soaked the city; a record flash flood.
We've had floods since the dawn of time, but we haven't seen 400 parts per million in CO2 levels for at least 800,000 years. It's basic physics: a warmer atmosphere holds more water vapor, loading the dice in favor of more extreme rain events.
At a recent talk in Breezy Point locals marveled at the 7 inches of rain that fell in one night in late June. The State Climate Office counts FOUR 1-in-1,000 year floods since 2004, just in Minnesota. No, it's not your imagination. The rain is falling harder.
We salvage another amazing day with blue sky & low humidity. T-storms rumble in this weekend, and a string of 90s may return by the end of next week. 100F highs aren't out of the question in about 7-8 days.
It looks like Chantal may fizzle, drenching Florida with tropical rains by Saturday. Meanwhile Super Typhoon Soulik is headed toward Taiwan with 140 mph winds. Puts the mosquitoes into perspective, huh?
Anniversary Of The Hottest Observed Temperature on Earth. Today's edition of Climate Matters focuses on heat, wildfires outside of Las Vegas, and why A/C in Tucson isn't optional these days: "100 years ago today, Death Valley, CA hit 134 degrees, the hottest temperature ever recorded anywhere on the globe. As we mark this anniversary, we also look at some of this year's heat records and stretches in the Southwest."
Except of an Alerts Broadcaster Briefing issued Wednesday:
* Tropical Storm Chantal has lost much of it's circulation, 40-45 mph sustained winds pushing toward Cuba. Hurricane formation is unlikely with this system, but the soggy remains of Chantal may spark inland flooding from Florida into the Gulf Coast by Saturday and Sunday.
* Soulik is approaching "Super-Typhoon" status, with sustained winds of 140-150 mph, expected to hit Taiwan by Friday (U.S. time) as a Category 2-3 storm capable of widespread damage and flooding. Coastal China will also see wind, storm surge and inland rainfall/flooding damage, but right now it appears Shanghai will be spared a direct hit.
Meanwhile, halfway around the world....
Summary: Chantal needs to be monitored, but right now the concern is more heavy rain and flash flood potential for Florida and the Gulf Coast than a significant risk of hurricane development or a major storm surge problem for coastal regions. We'll watch the storm carefully. I'm much more concerned about Typhoon Soulik and the implications for Taiwan and coastal mainland China, where damage may be extensive to severe by Friday. Facilities in Taipei will be impacted and this storm may deliver a significant structural and economic blow to Taiwan and coastal China within 72-96 hours.
