NHC has 50 knot wind field only extending out 50 nautical miles in the NE quadrant. The current pass of recon was out just over 100 nautical miles from the center in the NE quadrant and 10 second estimated surface winds by SFMR were around 50 knots out there. They are flying back toward center now in NE quadrant. Not sure if they will get to center, though eye is starting to come off NW coast of Dominica.
