MIAMI (AP) — Hurricane Humberto has formed over the Atlantic Ocean, although it's currently not threatening land. The former Hurricane Gabrielle is moving across the Azores, impacting the region with its residual effects. Humberto, located approximately 465 miles northeast of the northern Leeward Islands, is slowly progressing northwest and is expected to strengthen significantly into a major hurricane this weekend, according to the U.S. National Hurricane Center based in Miami. Meanwhile, Gabrielle has transitioned into a post-tropical cyclone that continues to exert influence on the Azores, prompting a hurricane watch for the entire Portuguese archipelago. As of Friday morning, Gabrielle was situated about 145 miles east-northeast of Faial Island with maximum sustained winds of around 65 mph. The storm is anticipated to weaken gradually but maintains a wide reach of tropical storm-force winds extending 160 miles inland. Observations recorded winds of 78 mph, which meet hurricane criteria. Although classified as post-tropical, Gabrielle still poses risks of severe weather impacts through the day. Gabrielle is moving east-northeast at 29 mph, expected to gradually move away from the Azores towards mainland Portugal by Sunday. In the Pacific, Hurricane Narda is currently a Category 1 storm but may regain strength. Narda is not posing threats to land, but a weakening trend is also anticipated for it in the coming days.
