So... You want to chase a tropical cyclone?



ANYONE that wants to chase a hurricane/typhoon/cyclone should watch this.  This is as real as it gets!  Thankfully Jim made it through Super Typhoon Haiyan okay, but he is still trying to get out of Tacloban City, Philippines.  Conditions are beyond horrible as the death toll will be in the thousands.  Very sad!  On a side note, fear is a ok (your mind preparing your body), just don't let it become panic!  See post below for more thoughts on that...  

Jim Edds interview hours before Super Typhoon Haiyan intercept:  http://stormvisuals.com/florida-weather/2013/11/7/video-storm-photographer-awaits-super-typhoon-haiyan-in-the.html

In the end, this was a horrific storm!  Near the very top at peak intensity.  HOWEVER, statements like "Haiyan was the most intense storm ever" = unknown and is likely overdone.  Keep in mind everything was based off satellite estimates NOT actual readings.  There was no recon (which stopped in the Western Pacific for the most part in 1987), there was no real observations, ONLY satellite estimates.  Unfortunately, you don't hear that fact much while watching most media outlets.

The JTWC estimated the pressure at 895 mb at landfall.  "IF" we assume that is correct, that still doesn't top the 1935 Labor Day Hurricane, which is still king in my eyes.  The 892mb was actually measured by a barometer (later verified), and not estimated by satellite.  Keep in mind the pressure gradient with the 1935 Labor Day Hurricane.  It had a 72.8 mb gradient over 12.5 miles.  Think about that for a second.  That's just beyond incredible as I think even the 185 mph maximum sustained winds (HURDAT Re-analysis) is probably underdone...



*Update...

Jim Edds now safe in Cebu and took the time today to share his experience with deadly Super Typhoon Haiyan. This is a follow up video interview with Jim from the one that I shared a few days ago about 2 hours before the landfall of the typhoon in Tacloban. - See more at: http://stormvisuals.com/florida-weather/2013/11/10/video-storm-photographer-shares-experience-with-deadly-typho.html#sthash.FI6xHKf5.dpuf

  1. It appears that Haiyan's central pressure was likely in the 885-890 mb range at time landfall occurred. A pressure reading of 889 from a handheld (Kestrel) was reported from Manicani Island south of Guiuan (within 5 miles of the center of the eye). Also the known pressure readings from Tacloban City by chasers (960 mb) suggest a central pressure between 890-900 mb based on 4 mb per mile (similar to the pressure gradient of hurricane Andrew at landfall in 1992).

  2. Thanks for the reply Perry. Until I see a post storm analysis, I'm taking everything I see with a huge grain of salt. IMO, from my calculations, I think 905 mb is more likely, but we'll see what the official report goes with in the end? Regardless, this wasn't a small compact storm like the 1935 Labor Day Hurricane, and I seriously doubt the maximum sustained wind speeds were as high no matter what estimates are reported. 72.8 mb over 12.5 miles...
