It continues to push toward the northern Leeward Islands, where tropical storm watches are now in effect as of the 8 p.m. update from the National Hurricane Center. Intensification is expected as Erin moves toward warmer ocean temperatures over the next several days.
The NHC said it currently expected Erin to become a Category 4 storm later Saturday but to eventually swerve away from the continental United States.
