Overview

• The National Hurricane Center says Humberto has strengthened to a Category 1 hurricane with 75 mph winds and is forecast to intensify into a major hurricane this weekend over the open Atlantic.
• A low is expected to form near the southeast Bahamas today from Invest 94L, with an 80% chance of development in 48 hours and 90% over seven days as it tracks northwest or north.
• Heavy rain and gusty winds from the disturbance are affecting Puerto Rico, Hispaniola, the Turks and Caicos and will spread into the Bahamas, bringing risks of flash flooding and landslides.
• Forecasters report increasing chances of wind, rainfall and storm-surge impacts along parts of the U.S. Southeast coast late this weekend into early next week, though model guidance remains split on track and timing.
• Potential interaction between Humberto and the developing system could alter their paths, and Hurricane Hunter data-gathering flights aim to reduce uncertainty; swells from post-tropical Gabrielle are already producing hazardous surf from Bermuda to the U.S. East Coast.
