Imagine, for a moment, this scenario. Two hurricanes are approaching the Southeast U.S. coast. They hit at the same time; one makes landfall in Miami, the other on Cape Hatteras. But even during their landfall, a third hurricane is developing in the western Atlantic and is forecast to make landfall on the Georgia coast just days later. Can you imagine the chaos? It sounds like a ludicrous futuristic prediction over the span of 700 miles of coastline, but that's just what happened in China this week.
I reported to you just five days ago how two simultaneous typhoon landfalls threatened the China coast. Incredibly, another storm (Typhoon Haikui) has made landfall near Shanghai overnight. That's three tropical systems in one week! I plotted their last typhoon strength locations, and landfall locations, using Google Earth and Unisys Hurricane data to produce the map above.*
The image above (showing the landfall location of Haikui) is similar to the one that I posted earlier this week showing Typhoon Damrey and Typhoon Saola; click on it to download an animation spanning from their landfall to today.
The Western Pacific, of course, averages many more tropical cyclones than the Atlantic and has them year-round (due to a larger surface area of warmer water). That is why (hopefully, unless you're a storm chaser) the Atlantic will never see such a fate. I don't know (because I don't have the data) how unusual this is for that basin, but I would assume it is rare.
*NOTE: The UNISYS data doesn't specify whether the storms were typhoons or tropical storms at landfall and I'm not even sure that information exists, so I'll leave that up to the interpretation of the reader for now.
Twenty five years ago this morning, I awoke to a loud tempest of wind and rain in North Carolina. Today, I take a look at new maps and information available.
A very impressive-looking Category 3 Hurricane Odile slammed into the Baja California Peninsula of Mexico Sunday. Now, a new threat for the Southwest U.S.: major flooding.
I found three security cameras that caught the light from the Sunday night fireball, including two from my house.
The iPhone 6 - with barometer - and Apple Watch were announced today, but I've been wearing barometer watches for 30 years.
I was pleased to serve on an AMS panel "The Impact of Ubiquitous Data Availability and Social Media" at the summer community meeting.
Last weekend, I presented the weather science side of UFOs at a paranormal conference in Johnstown, Pennsylvania. Since then, there have been several local UFO sightings of note.
