Tropical alerts have been issued in the northeast Atlantic as the second hurricane of the season crosses back over the basin.

Forecasters say a hurricane warning has been issued for the Azores as Hurricane Gabrielle races across open Atlantic waters on track for the volcanic archipelago.

Hurricane Gabrielle passed Bermuda Monday night as a powerful Category 4 hurricane and is moving into the open Atlantic, the NHC said.

As Hurricane Gabrielle moves east across the Atlantic, forecasters keep an eye on two tropical waves that could develop into a tropical storm or hurricane in the coming week.

Maximum sustained winds in the newly formed Hurricane Gabrielle increased to 90 mph overnight, according to the latest report from the National Hurricane Center. The storm is expected to strengthen over the next day or so and could become a major Category 3 hurricane by Monday night, forecasters said.
