NHC: Grace to make landfall Saturday; Henri close to hurricane strength

Forecasters issued a hurricane watch Friday morning for Tropical Storm Henri ahead of its projected track toward the southern New England coast.

Henri was expected to intensify into a hurricane by Saturday, the U.S. National Hurricane Center said in an advisory. Impacts could be felt in New England states by Sunday.

The hurricane watch stretched across the South Shore of Long Island from Fire Island Inlet to Montauk, and the North Shore from Port Jefferson Harbor to Montauk. It also covered the coast from New Haven, Connecticut, to Sagamore Beach, Massachusetts; and Nantucket, Martha's Vineyard, and Block Island.

Additional strengthening is expected during the next couple of days and Henri is expected to become a hurricane by Saturday and be at or near hurricane strength when it makes landfall in southern New England.

The main threats were expected to be storm surge, wind, and rain.

Meanwhile, Hurricane Grace has gained strength and is now packing 90 mph winds.  Grace made landfall early Thursday morning just south of Tulum, Mexico as a hurricane before weakening to a tropical storm and then gaining hurricane strength again.

A second landfall is expected Friday night. 

On the forecast track, the center of Grace is forecast to move across the southwestern Gulf of Mexico Friday evening, and then make landfall along the coast of mainland Mexico within the hurricane warning area.

Strengthening is forecast until Grace makes landfall, with rapid weakening expected as Grace moves inland over the mountains of central Mexico. 

Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 185 miles.
