They probably know the airport is shutting down and just saying f it. Haha yeah. Personally, I'd be doing 0200-0800 and +SHRA. Hell, throw some PY in there too, since it looks like they're close to water. I mean, if you're gonna forecast 140kt sustained, might as well go all out.

lakeeffectkid383 Posted September 6, 2017 Share Posted September 6, 2017 Does NHC leave the cone as is at 11 or move it east based on latest model trends and early 00z hurricane models? I think they're pretty far west now compared to most guidance, but then again they have the Euro on their side and that's never a bad thing. Tough call Link to comment Share on other sites More sharing options...

Hoosier Posted September 6, 2017 Share Posted September 6, 2017 The timing/sharpness of the northerly turn somewhere near Florida has gotten a lot of attention, but also important to watch a less obvious turn before then. Much of the guidance has a subtle bend to the west commencing north of Hispaniola. How exactly that plays out could matter down the line. Link to comment Share on other sites More sharing options...

Coach McGuirk Posted September 6, 2017 Share Posted September 6, 2017 Do the hurricane hunters actually go into the storms at 1,500 ft these days when it's this strong of a hurricane? Link to comment Share on other sites More sharing options...

That was found about 23-24m above the surface IIRC from a poster who posted earlier. Not much but 75 feet off the ground isn't the "surface" to NHC. Hope they do as it would be awesome to see this tie Allen but I'm doubtful right now. I think 185mph is a good spot to stay at 11. Link to comment Share on other sites More sharing options...
lwg8tr0514 Posted September 6, 2017 Share Posted September 6, 2017 40 minutes ago, Sophisticated Skeptic said: I mostly agree, but still think Florida will be spared the direct hit. Once the models can fully grasp the strength of the trough along the east coast, IRMA will head north. GA, SC , NC I feel currently have the best chance of getting a direct hit. Actually not, look at ensembles and looks like the eye coming ashore in Broward county and skirting the coast, Cat 4 winds all the way inland to Lake Okeechobee, not exactly sparring Florida. The big right turn as a fish or beelining to the Carolinas and sparing all of Florida is looking more like wishcasting right now. Link to comment Share on other sites More sharing options...

Dunkman Posted September 6, 2017 Share Posted September 6, 2017 The NOAA HHs are flying this mission at 750mb. At the end of the last pass that was at 8300 ft. In the center of Irma it was 5700 ft. Link to comment Share on other sites More sharing options...

Lost an engine too. Here you go. Since we are all waiting for flight data I guess this can stay here. Both the WC-130 "Hercules" and the WP-3 "Orion" operate most efficiently at altitudes of 24,000 to 30,000 feet. Since most storms occur some distance from the aircraft's home station the crew usually flies to the storm at high altitudes to conserve fuel. About 200 miles from the storm the aircraft descends to its storm operating level. If the storm is in its infancy such as a depression or tropical storm with winds less than 50 ,mph, the crew operates as close to the surface of the sea as possible--from 500 to 1500 feet. If the storm is more fully developed, either a hurricane or a strong tropical storm, the aircraft flies its pattern, including penetrations to the center, at 10,000 feet altitude. A typical mission will last from 10-12 hours during which time the crew will penetrate to the center of the storm anywhere from 3 to 6 times. When the mission is completed, the aircraft will climb back to high altitude for the trip home. http://www.washingtonpost.com/wp-srv/weather/hurricane/info/recon.htm Link to comment Share on other sites More sharing options...

Tough call Unless I'm mistaken, it is only the 18z GFS that has shifted a bit east. Why would the cone change significantly just due to one model having moved east? What if it's an outlier or a anomaly? There would need to be a general trend, or a good solid reason to think the 18Z GFS was "more right" than everything else.

Random Chaos Posted September 6, 2017 Share Posted September 6, 2017 Seems to have weakened slightly - cloud tops have warmed, it is slightly asymetric now, and recon is only finding about 175mph winds (as oppossed to the 185-190mph earlier).

JasonOH Posted September 6, 2017 Share Posted September 6, 2017 The concentric eyewalls are visible on radar. Some recon passes show the spike of the second eyewall. They are super close together so it could be a very clean cycle. Link to comment Share on other sites More sharing options...
HKY_WX Posted September 6, 2017 Share Posted September 6, 2017 To me, the most populated location that's going to get destroyed is St Martin. They are in the path of the eye itself.
