Henri will probably become a 90 mph hurricane by early Sunday as it rides north off the East Coast, where atmospheric steering currents will enter the equation. A dip in the jet stream carrying cool air at the upper levels, and reducing air pressure, will be positioned to the west, swinging over the Mid-Atlantic by Saturday. That could help “capture” Henri, guiding it due north, perhaps into southern New England.
