Unseasonable Warmth for Central USA While Category 4+”Eta” Threatens Central America

Second or Third Warmest Election Day on Record for MSP. There’s a pretty good chance the official high will reach 68F, the second warmest November 3 on record in the Twin Cities. Graphic: Twin Cities National Weather Service.

Moderately Cold by Mid-November. Jet stream winds buckle within 1-2 weeks with more Canadian than Pacific air infiltrating the USA, pushing any lingering warmth into far southern states. It was a good run whileit lasted, I guess.

Super Typhoon Goni Slams into Philippines as Strongest Landfalling Tropical Cyclone on Record. Dr. Jeff Masters has eye-opening statistics about the mega-hurricane that just hit the Philippines at Yale Climate Connections: “…Goni was the strongest landfalling tropical cyclone in world recorded history, using one-minute average wind speeds from the National Hurricane Center for the Atlantic/northeast Pacific and one-minute average winds from JTWC for the rest of the planet’s ocean basins. The previous record was jointly held by Super Typhoon Meranti, which made landfall on September 16, 2016, on Itbayat Island, Philippines, and Super Typhoon Haiyan, which made landfall on November 8, 2013, on Leyte Island, Philippines. Both had maximum winds of 195 mph at their peak intensity, but made landfall with 190 mph winds, according to JWTC. There are no official world records for strongest landfalling storms, since the JTWC does not routinely assign landfall intensities in their post-season summaries (though they did make an exception for Super Typhoon Haiyan)…”

How African Dust Storms Create Caribbean Beaches. Mental Floss has a fascinating post; here’s the intro: “The fertile red soils of Bermuda and the rich coral reefs of the Bahamas are a geological mystery. Both are made up of a specific combination of alien minerals and nutrients not found anywhere on the islands or in the ocean that surrounds them. Scientifically speaking, they should not exist. But over the last decade, geologists have come up with an explanation for these ecological anomalies: They originated 5000 miles away in Africa. For more than a million years, dust from the Sahara Desert has hitched a ride on westward-traveling winds to the Caribbean. Bermuda and the Bahamas are, quite literally, an extension of the world’s largest desert…”
