Overview

• The National Hurricane Center says Humberto reached hurricane strength Friday and is forecast to intensify into a major hurricane over the weekend while remaining offshore between the U.S. and Bermuda.
• A low is expected to form near the southeast Bahamas with a high chance of becoming a tropical depression or Tropical Storm Imelda this weekend, likely moving north or northwest across the Bahamas.
• The proximity of the two cyclones could produce a Fujiwhara effect, leaving track and intensity forecasts unusually uncertain, with outcomes ranging from a Carolinas approach to a turn out to sea.
• The hurricane center reports an increasing risk of wind, rainfall, storm surge and dangerous surf for portions of the Southeast coast late this weekend into early next week and urges close monitoring.
• Even without landfall, long-period swells and rip currents are likely for Bermuda and much of the U.S. East Coast as Gabrielle and Humberto send hazardous surf toward the shoreline.
