Windspeed Posted September 16, 2017 Share Posted September 16, 2017 I posted this last night in the main Atlantic discussion thread. My thoughts haven't changed. Anxious to see if the 12z ECMWF release in about an hour continues to kick out Jose much faster for downstream implications with a future Maria and the CONUS. Obviously the more immediate dire cause to worry is the Antilles.Big changes in the 00z ECMWF downstream. It still brings a hurricane through Lesser Antilles, PR/DR, but swiftly ejects Jose OTS and rebuilds heights over the Mid-Atlantic region. That screams CONUS threat. Also the 500-200 mb analysis looks sobering with regards to both GFS snd Euro through 5 days. We need the vort to take as long as possible in consolidating a core. Otherwise, in the event it gets going, I see little in the way of preventing a period or periods of significant rapid intensification either before or up until interaction with the Greater Antilles. Still too early to rule out the possibility of more latitude gained and another sweep through the more northern Lesser Antilles/Virgin/PR islands as well. And of course the more southern track into Hispaniola is always a recipe for massive loss of life. We don't even have a classified system yet and I'm getting nervous mainly because anywhere near that region right now seems cruel by the Gods. Either way it doesn't look good as this won't avoid land. Best we can hope for is slow development, fast motion and a weaker cyclone.Edit: Jtm12180, if you don't mind maintaining, updating and editing the title of the thread over the coming days, this can continue on as the main discussion thread for Maria.

salbers Posted September 16, 2017 Share Posted September 16, 2017 Compared with 00Z GFS run, the hit is farther north. This corresponds with more of a piece of the trough in the Rockies lifting out over the Great Lakes. It seems if we can get the trough to stay consolidated in the Rockies the downstream ridge would build up and steer it more south. This will be interesting to watch from run to run.

Amped Posted September 16, 2017 Share Posted September 16, 2017 The center is well south of where NHC has it. Should probably be a TS at the 5pm. Link to comment Share on other sites More sharing options...

Windspeed Posted September 16, 2017 Share Posted September 16, 2017 Banding is getting stronger. And I agree that the center may be south of track and model initialization. It was difficult to define an exact location earlier but that is no longer the case. This looks like a tropical storm. Would be surprised if this isn't upgraded to Maria at the 5 PM EST advisory. This is getting together fast. Link to comment Share on other sites More sharing options...
MattPetrulli Posted September 16, 2017 Share Posted September 16, 2017 12z Euro coming in much stronger than 00z, 975 MB and looks like a direct hit to PR and DR. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted September 16, 2017 Share Posted September 16, 2017 Boy, the models just can't decide what Jose is going to do, which means they also don't know what Maria will eventually do. Last night's euro swept Jose up and away, opening the door for Maria. The 12z once again has Jose stalling and drifting south, eventually grabbing Maria and pulling it out to sea with it.

Stay away from PR and those Virgin Islands dirty cyclone! Wow what a hurricane season. They warned us it would be a bad one and they were right. They have it around 90mph in the vicinity of PR -- watch it be way stronger. Link to comment Share on other sites More sharing options...

Windspeed Posted September 16, 2017 Share Posted September 16, 2017 12z ECMWF flips back to stalling Jose instead of the 00z swift OTS solution. That results in some crazy fujiwara and phase play. This is going to be another one of those wait and see tracks. May take another day or two before the Euro gets a better handle on Jose for downstream CONUS impacts with Maria.

donsutherland1 Posted September 16, 2017 Share Posted September 16, 2017 Maria, now a tropical storm, was situated at 12.3°N, 52.6°W. According to historic climatology, just under 1-in-5 tropical cyclones that formed within 100 nautical miles of Maria's area of development made U.S. landfall. However, a large number of those systems tracked generally westward, many dissipating in the process. The synoptic pattern as currently modeled argues against such a scenario. Therefore, excluding the systems that tracked generally westward and failed to make a turn more to the north, the smaller sample yields a landfall probability closer to 2-in-5. That's quite high. Notable systems that made U.S. landfall included Hurricanes David (1979), Frederic (1979), and Ivan (2004). At least for now, Maria bears watching.

What would be awesome is if you could do the day 3 and/or day 5 NHC forecast positions as well. Maybe even create a weighted average (maybe like 40% current, 40% d3 and 20% d5). Obviously would be a lot of work, assuming you do it manually, but it would be a genuinely helpful metric for forecasting. Link to comment Share on other sites More sharing options...
