NCWX Posted September 5, 2017 Share Posted September 5, 2017 My uncle who has a house in Key West said the cop that lives next told him at the 2 pm advisory if it is stronger they are being told the state will issue a full and complete mandatory evacuation of all the FL keys effective by noon tomorrow.

jbenedet Posted September 5, 2017 Share Posted September 5, 2017 4 minutes ago, gakmsg said: Very concerned about St Kitts - Still slightly south east of them at this hour and the hoped for northern turn may now bring Irma right over them. This may sound like hyperbole, but I don't know how anyone who is in the direct path that has less than 30' ASL is comfortable riding this out... 7ft - 11 ft surge. Then put massive breakers on top of that. Link to comment Share on other sites More sharing options...
NJwx85 Posted September 5, 2017 Author Share Posted September 5, 2017 Ryan MaueVerified account @RyanMaue Wind speed of Hurricane #Irma is very high for central pressure of 929 mb & cloud tops have warmed in past 6-12 hours ... Ryan MaueVerified account @RyanMaue Expecting eyewall cycles to modulate intensity & should see bursts of "pink" or very-cold cloud tops & pressure should fall = stronger yet Link to comment Share on other sites More sharing options...

Any inconvenience such an evacuation might cause would be trivial compared to the danger of a Category 5 hurricane. Should Irma retain or increase its strength and should the guidance continue to show a potentially devastating passage over the Florida Keys, such an evacuation would make good sense.

Paleocene Posted September 5, 2017 Share Posted September 5, 2017 I'm sorry if this has been posted before or if this is the wrong place, but here is a really good article from Houston area meteorologist Eric Berger about hurricane modeling. It was published this AM. https://arstechnica.com/science/2017/09/at-times-during-harvey-the-european-model-outperformed-humans/ Apparently the HMON performed like trash during Harvey: "the HMON model's average error at four days was a staggering 630 nautical miles, compared to about 170 nautical miles for the European model.

Hurricane Allen had the strongest winds in the Atlantic at 190MPH sustained, Hurricane Wilma had the lowest pressure in the Atlantic at 882mb, Hurricane Patricia had the strongest non-tornadic sustained winds on the planet at 215MPH sustained with a pinhole eye, and finally Typhoon Tip had the lowest projected non-tornadic pressure pegged at 870mb...

Wilma exploded in size later and became larger, but at the time of that lowest pressure reading Wilma was a tiny storm with a remarkably small eye.

" It's the same thing with Irma too. HMON has an average error of about 600 miles and humans are at 200 miles. The Euro is annihilating humans right now with an average error of 100 miles at D5 forecasts. Link to comment Share on other sites More sharing options...
