High pressure prevails northeast of the basin. Moderate to fresh winds cover most of the basin, locally strong near the northern coast of Colombia, and light to moderate in the southwest Caribbean. Seas are mainly in the 4 to 7 ft range, locally to 8 ft near the coast of colombia, and 2 to 4 ft in the southwest Caribbean.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

At 5 a.m. EDT, the center of Hurricane Henri was located over the Atlantic Ocean about 80 miles (125 km) south-southeast of Montauk Point, New York, and about 120 miles (190 km) south of Providence, Rhode Island. Henri is moving toward the north near 18 mph (30 km/h). A decrease in forward speed and a turn toward the north-northwest is expected this morning. On the forecast track, Henri is expected to make landfall in southern New England or on Long Island late this morning or early this afternoon. After landfall, a turn to the north and a slower forward speed are expected as Henri moves over southern New England.

Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The latest minimum central pressure estimated from Air Force Hurricane Hunter data is 986 mb (29.12 inches). Little change in strength is expected this morning, and Henri is forecast to be at or near hurricane strength when it reaches the coasts of southern New England and Long island. Rapid weakening is expected after Henri makes landfall.

Grace has mainly dissipated over the mountains of Mexico to a tropical rainstorm as it continues to move to the west. Grace may re-form over the warm water of the eastern Pacific Ocean over the next few days, but if it is named, it is likely to take a new name.

We are also watching a few tropical waves, either across the tropical Atlantic or emerging off the African coast this week, but development with these seems unlikely for the next few days.
