Hurricane Gabrielle Prompts Closures in Azores as Storm Approaches

Azores Prepares for Hurricane Gabrielle's Impact

The autonomous region of the Azores, Portugal, is currently under alert as Hurricane Gabrielle approaches, prompting widespread closures and emergency preparations. The storm, which once reached Category 4 strength, is forecast to bring significant weather impacts to the archipelago late Thursday, September 25, 2025, into Friday, September 26, 2025.

In response to the impending threat, the Azores government has issued orders for the temporary closure of various public services and educational institutions. All public services and entities located on the western and central group islands are mandated to close from 6 p.m. on September 25 until 6 p.m. on September 26. This directive includes the closure of school establishments, with exceptions made for urgent and essential services such as hospitals, health centers, and civil protection operations.

Storm Intensity and Forecasted Conditions

While Hurricane Gabrielle peaked as a major Category 4 storm east of Bermuda, it is expected to approach the Azores as a hurricane or high-end tropical storm, potentially maintaining Category 1 status. As of Thursday afternoon, September 25, Gabrielle was approximately 455 miles (730 kilometers) west of the Azores, with maximum sustained winds of 75 mph (120 kph). Despite being downgraded to a post-tropical cyclone, forecasters warn that it will still deliver hurricane-force conditions.

The Portuguese Institute for Sea and Atmosphere (IPMA) and the National Hurricane Center (NHC) have issued warnings detailing the expected conditions. Forecasts indicate sustained winds of 120–165 km/h, with gusts potentially exceeding 200 km/h in exposed areas. Heavy rainfall is anticipated, with up to 5 inches (13 centimeters) possible across the central Azores and up to 3 inches (8 centimeters) in the eastern and western islands, raising the risk of flash flooding and landslides.

Potential Impacts and Regional Outlook

Beyond wind and rain, the Azores are bracing for a dangerous storm surge accompanied by large and destructive waves, which could exceed 10 meters (33 feet) offshore, leading to significant coastal flooding in low-lying areas. Power outages and localized structural damage are also considered possibilities. Red warnings are specifically in effect for the Western and Central group islands, including Flores, Corvo, Faial, Pico, São Jorge, Graciosa, and Terceira.

Following its passage through the Azores, Gabrielle is projected to continue its eastward trajectory, affecting parts of western Europe, including mainland Portugal, Spain, and France, as a tropical wind and rainstorm over the weekend. Swells generated by the hurricane are also expected to impact distant regions, including Bermuda, the U.S. East Coast, and Atlantic Canada, potentially causing life-threatening surf and rip current conditions.
