Tropical Storm Jerry is expected to strengthen as it moves northward towards Bermuda, turning east before reaching the island early next week.
Meanwhile, Post-Tropical Storm Karen has weakened, located about 675 miles north-northwest of the Azores.
It also marked the furthest north a tropical system has developed since records began in the 1850s.
Tropical Storm Jerry is the storm to watch, while Karen's strength diminishes.
