Synopsis: Cut-off low is forming near 24N/27W, and will move W towards 33W through tomorrow morning, deepening into a strong cut-off low. Cut-off then broadens while continuing W towards 35W through morning of the 10/12, breaking down into an inverted trough extending N from near 22N towards 33N between 40W and 30W by morning of the 11/12. Ridging extends SW towards 20N between 50W and 30W this morning from strong high pressure over the Azores. Ridging will weaken but continue to bend around W side of the cut-off noted above through the 10/12 while sliding W in between 55W and 40W. Ridging finally gives away into the 12/12 as inverted trough continues to broaden and move W across the central Atlantic. Broad inverted trough of low pressure extends between 70W and 55W this morning from N Caribbean N towards 35N, and will remain in place through tomorrow while weakening. Conclusion: Strongly recommend avoiding grids CC and DD as well as N HH and II through the next two days to avoid strong gusty winds, large swells, and heavy squalls associated with the cut-off low. Please note below forecast for grid HH is for SE half of the grid, as N and NW portion of the grid will see much larger swell and WNW winds by tomorrow. Further West, ridging extending SW into grids KK and JJ will lead to enhanced NE conditions, though these will tend to lower in coming days as ridging weakens as noted above. Lighter airs across RR today will increase through tomorrow as above noted inverted trough weakens and allows for more enhancement of trades across the grid. GG:
