typhoon   Click the image to enlarge.  Look at this satellite loopThe typhoon has weakened as it has moved through the Philippine Islands.   Typhoon Haiyan reached Category 5 status with estimated winds of 150 knots (172 mph).  Check out this cool picture of the typhoon and the entire Earth.  While the storm has passed peak intensity, this will be a very strong storm as it moves through the central Philippines.   The storm will likely have very destructive winds and extreme rainfall which will lead to mudslides and flooding.  People near and north of where the eye hits should seriously consider evacuating north or south out of the path of strongest winds.   A Storm Surge of 17 feet is forecast!   A weakened storm will eventually move into Vietnam.   This will not be a recurving storm.   Here’s the typhoon discussion, warning text, wide satellite view, nice visible satellite imagesatellite images of the storm, and Philippines radar.

    Sustained winds of 190mph with gusts up to 230mph. Highest recording since 1979.


    Pray for the Philippines

  2. Travis (Oakland County) says:

    Sustained winds now 195+ mph and still strengthening!


    On the verge of becoming Earth’s most powerful storm ever recorded.

      It definitely ranks up there. Too bad we don’t have aircraft measurements for Haiyan like we did with Megi. Here is a comparison of the two storms:



      Haiyan is at the top of the Dvorak satellite intensity estimation scale. 895 mb pressure estimate seems conservative. Haiyan is up there near the theoretical maximum intensity for a tropical cyclone, according to our understanding of physics. It joins an exclusive club of storms.

    Satellite measurement in with a measurement of 858mb. If confirmed, this would be the new world record. Too bad, there probably won’t be “official” measurements able to be taken.

      Nothing short of incredible.

    What is the difference between a typhoon and a hurricaine?

    1. Bill Steffen says:

      They are the same thing…hurricanes are called hurricanes in the Atlantic Ocean and in the Eastern Pacific Ocean (east of the Dateline). They are called typhoons in the Western Pacific Ocean and they are called cyclones in the Indian Ocean. On rare occasion they are called “willy-willies” in Australia.
