Overview

• Hurricane Gabrielle crossed the Azores with damaging winds, coastal flooding and large waves, and late-day updates show it transitioning to post‑tropical while hazardous surf continues for Bermuda, the U.S. East Coast and Atlantic Canada.
• Tropical Storm Humberto in the central Atlantic is forecast to become a hurricane within days and could reach major strength, with most guidance keeping it offshore and passing near or west of Bermuda early next week.
• A nearby disturbance labeled Invest 94L, now producing heavy rain over Puerto Rico and Hispaniola, has a National Hurricane Center formation chance of about 50% in 48 hours and 80% over seven days, with development likely near the Bahamas this weekend.
• Forecasters warn the proximity of Humberto and the developing system could trigger a Fujiwhara effect that alters tracks, with scenarios ranging from absorption and a turn out to sea to a separate system tracking closer to the Carolinas early next week.
• Model guidance remains split, and officials urge residents in the Bahamas, Bermuda and along the Southeast and Mid‑Atlantic coasts to monitor NHC updates as rip currents, rough surf and periods of wind and rain are possible even without a U.S. landfall.
