Karen is forecast to move towards the northeast and then east through Friday.
The National Hurricane Center expects Karen will slow down and make a clockwise loop over the southwestern Atlantic into the weekend. Karen is expected to weaken as it moves into an unfavorable environment with drier air and wind shear. It is expected to become a depression by Friday and likely a remnant area of low pressure by this weekend.READ MORE: Parkland School Shooting Victim Alex Schacter Posthumously Inducted Into UConn Fraternity
There’s uncertainty regarding the track and intensity this weekend and early next week because Karen may weaken and dissipate as it meanders south of Bermuda. The CBS4 Weather team will continue to watch it closely.
