Brick Tamland Posted August 30, 2017 Share Posted August 30, 2017 Hope this curves out to sea, but unfortunately that might not be the case. The first two weeks of September are notorious for big hurricanes in NC, too. Link to comment Share on other sites More sharing options...

Windspeed Posted August 30, 2017 Share Posted August 30, 2017 What's the foward speed on this thing? It might just be the IR image but that thing looks like it's bookin it! Three hour intervals between frames in that gif make it appear to be moving faster. But it's a steady 10-12 kts W, or just S of W.Looking out a few days ahead, some dry mid-levels exists across the MDR northwest of Irma; however, the tropical storm has developed rather quickly and may be able to fight that off if it establishes a robust core. Mid-level easterly flow behind Irma should remain in a moist envelope, especially south and southeast of the circulation. As long as any mid-to-upper westerly flow remains at a good distance northwest to Irma's circulation, the system should be able to traverse the MDR and intensify slowly/steadily.Speaking of SAL, it has decreased some over the past week and should decrease further. A mid-to-upper level low and trough is forecast to form and move south from the Azores as ridging spreads west. That will likely further weaken northeasterly flow and halt the SAL even further. I don't know how long this will persist, but I do expect the overall pattern to be more favorable for Cape Verde and MDR systems this September than in recent years.

NorthArlington101 Posted August 30, 2017 Share Posted August 30, 2017 What is unique about this storm seems to be the jog to the SSW (or WSW) that is eventually going to make. That would put it in a zone with better odds. Link to comment Share on other sites More sharing options...

That would put it in a zone with better odds. That jog puts it in the 30-40% region, and that jog is modeled very well because of the ridge that gets forced with the remnants of Harvey and the low near the Canadian Maritimes. Irma will slide right underneath that ridge. Only caveat could be a weakness to the NW of the low that could draw Irma to the right, though only the GFS has that weakness there.

MJV Posted August 30, 2017 Share Posted August 30, 2017 'Tis the season---once again---this is a great place to catch the 'drift' of where I can start looking at 'where to focus'. I'm watching --- as to whether or not --- Irma tracks south of Cuba (in one way, shape or form). If so... batten down the hatches here and where I live. I will say this though --- "you really can't flood a swamp". And I'm at 22' MSL with 14.16" of rainfall for the month of August so far! Panther Run's no where close to 'cart path only'. Spectacular day here today---Cheers Link to comment Share on other sites More sharing options...
Hazey Posted August 30, 2017 Share Posted August 30, 2017 The models are very bullish in bringing Irma to major status in the long range. Track is still very uncertain, as it should be at this point but it's looking more like there will be a beast of a storm prowling around somewhere in the Caribbean area in 8-10 days.

Conditions get very favorable after a few days. Looking like a classic CV buzzsaw. Link to comment Share on other sites More sharing options...
OSUmetstud Posted August 30, 2017 Share Posted August 30, 2017 Will it stay far enough south in that 7 to 10 day range to miss the weakness to the north? I think thats the big question. Link to comment Share on other sites More sharing options...
eurojosh Posted August 30, 2017 Share Posted August 30, 2017 Euro through 120 is faster, weaker, and further south. Short term strengthening could be the key to track - as the midatlantic ridging doesn't look wildly dissimilar between the models. Link to comment Share on other sites More sharing options...
SnowGoose69 Posted August 30, 2017 Share Posted August 30, 2017 If this hit somewhere as a major it would have only spent one cycle on the list with back to back retirements of the same letter. I'm trying to remember the last storm to do that. I don't think it was long ago Link to comment Share on other sites More sharing options...
csnavywx Posted August 30, 2017 Share Posted August 30, 2017 Wave break in the Pacific is going to wreak havoc with the downstream pattern. Going to be a lot more adjusting going on. Link to comment Share on other sites More sharing options...

Windspeed Posted August 30, 2017 Share Posted August 30, 2017 ECMWF continues to extend ample 500mb ridging into western Atlantic. You'll notice an upper trough or mid-to-upper low that comes down out of the Azores. Also a strong trough digs into the interior US Great Lakes and Midwest. This screams increasing heights and an amplified ridge from central Atlantic over Bermuda. Irma will likely take a south of west track near to or just north of the northern lesser Antilles based on that steering flow. The big question for the Bahamas and CONUS is if the interior US trough digs off the coast or lifts and allows ridging to flatten into the Southeast US. Way too far out and could change drastically in the coming days. But the setup will at least get Irma into the western Atlantic. Where does it go from there?

hawkeye_wx Posted August 30, 2017 Share Posted August 30, 2017 The 12z Euro delays the formation of a new western gulf storm just enough so that it gets missed by the eastern trough. The storm then sinks deep down into the Bay of Campeche. This scenario would theoretically help open the door for Irma(assuming the trough can lift out) vs previous runs which showed the gulf system being pulled into the northeast gulf as Irma approached the Bahamas.
