Regan Posted September 18, 2017 Share Posted September 18, 2017 44 minutes ago, shaggy said: So basically the euro from the other night filled Jose in and ran Maria right into NC on a steady NW motion. The GFS was stronger and took Jose further south towards bermuda and ejected maria out to sea. It seems as if the two models have swapped solutions for the time being. Pretty much. But honestly, they could swap again or just show us something new. We are about 9 days out give or take. Ages. Nothing would surprise me this season. I'm not ready to bet on any model.

Roger Smith Posted September 18, 2017 Share Posted September 18, 2017 Maria is on a track running slightly north of that taken by the Great Hurricane of October 1780 which ran from just north of Barbados (on Oct 9) across St Lucia and Martinique then northwest to the Mona Passage west of Puerto Rico. That storm killed over twenty thousand people and from the damage reports must have been a cat-5 when north of Barbados. This storm apparently tracked north-northeast after leaving Hispaniola and missed Bermuda slightly to the southeast. Another interesting factoid is that there had been two previous major hurricanes (three counting one in June), one of which hit New Orleans on August 24 and the other hitting Cuba and the Bahamas about a week before the Great Hurricane. And there was to be yet another major hurricane in the eastern Gulf of Mexico ten days later. 2 Link to comment Share on other sites More sharing options...
Windspeed Posted September 18, 2017 Share Posted September 18, 2017 Dominica has a pretty sharp incline in topography from sea floor and shoreline. Surge isn't as big an issue even for the water fronts. Maria, though intense, has a very small vortex besides. This is obviously an extreme wind event for the island. Dominica also has 1,400 meter volcanic peaks and unfortunately there are residences located up on the sides of ridges above towns. Elevated structures may be subject to higher gusts. Mudflows are always an issue on volcanic terrain but at least the ridges and peaks are heavily vegetated. Link to comment Share on other sites More sharing options...

bluewave Posted September 18, 2017 Share Posted September 18, 2017 Maria is looking like potentially the strongest hurricane landfall in Puerto Rico of the satellite era. http://www.aoml.noaa.gov/hrd/hurdat/International_Hurricanes.html #Maria could be only the 4th category 4 #hurricane landfall on Puerto Rico since 1851- last one was in 1932- the notorious San Ciprian stormpic.twitter.com/6LHywya9hH 8:14 AM - 18 Sep 2017 Link to comment Share on other sites More sharing options...

Windspeed Posted September 18, 2017 Share Posted September 18, 2017 You think Dominica will have an effect? I personally don't think they'll be enough to significantly hinder the storm.A direct track over the island will have some effect though the NHC can't realistically forecast that due to it being such a small island. The vortex of Maria is tiny. This isn't a huge 25nm diameter eyewall like Irma that was able to engulf Lesser Antilles islands with peaks without much effect. Such a small eyewall in Maria crossing a 4,700 ft peak/ridge may interact enough to hinder the LLC but that doesn't mean it will cause significant weakening. The disruption may be enough to temporarily pause ongoing intensification however. Again, that will likely be temporary. Link to comment Share on other sites More sharing options...

wxeyeNH Posted September 18, 2017 Share Posted September 18, 2017 Maria's small eye is amazing. The pressure has to be so much lower than the last recon. When is the next plane due in? The eye is so small that the exact path of the eyewall will be crucial. The 5pm track over PR is also the worst possible. Puts San Juan in the right front quad with screaming winds from the east right off the ocean. Most of the 3 million people live in the northeast part of the island....

Superstorm93 Posted September 18, 2017 Share Posted September 18, 2017 One for the books Hurricane Maria Discussion Number 10 NWS National Hurricane Center Miami FL AL152017 500 PM AST Mon Sep 18 2017 Maria is developing the dreaded pinhole eye. The last reports from an Air Force Reserve Hurricane Hunter aircraft and radar data from Martinique indicated an eye with a diameter of about 8-10 n mi, and this featured has recently become better defined in visible and infrared satellite imagery. The aircraft data supported an intensity of 105-110 kt back at 18Z, and all indications are that rapid intensification is continuing. Thus, the initial intensity is increased to 115 kt. Another Hurricane Hunter aircraft is schedule to arrive in Maria about 2330Z, and it is distinctly possible that it will find a higher intensity than 115 kt. 1 Link to comment Share on other sites More sharing options...
