On the forecast track, the center of Dorian will move across the northeastern Caribbean Sea tonight, pass over or near western and central Puerto Rico on Wednesday, and move near or just east of eastern Hispaniola Wednesday night.

Additional Hurricane Discussions

The NOAA’s 11 a.m. discussion included some more details.

“Dorian moved directly across the center of St. Lucia around 1000 UTC, which resulted in a significant disruption of the small inner-core wind field. An Air Force Reserve reconnaissance aircraft had difficulty identifying a clear-cut center and radar data from Martinique indicates that the mid-level circulation has also been disrupted somewhat. Having said that, the overall appearance of the cyclone in both satellite and radar imagery has improved since this time yesterday, although a pronounced dry slot is now evident in the southeastern quadrant of the circulation. The initial intensity of 45 kt is being maintained based on aircraft flight-level and SFMR surface wind data.

The initial motion remains west-northwestward or 295/11 kt. There is still no significant change to the previous forecast track or reasoning. Although the inner-core wind field and low-level center have been disrupted, the overall circulation envelope has remained
intact and is expected to move west-northwestward to northwestward for the next 36-48 hours toward a break in the subtropical ridge located well north of Dorian.”
