RECON AIRCRAFT TO INVESTIGATE GABRIELLE TODAY…EXPECTED TO BECOME A HURRICANE AND PASS EAST OF BERMUDA SUNDAY NIGHT AND MONDAY

According to the NHC advisory number 14

Gabrielle is moving toward the northwest near 13 mph (20 km/h), and this general motion is expected to continue through tonight. A turn toward the north-northwest is forecast on Sunday, followed by a turn toward the north and northeast Monday and Monday night. On the forecast track, the center of Gabrielle is expected to pass east of Bermuda Sunday night and Monday. Maximum sustained winds are now near 60 mph (95 km/h) with higher gusts. Continued gradual strengthening is forecast, and Gabrielle is expected to become a hurricane by Sunday. Air Force Reserve and NOAA Hurricane Hunter aircraft are scheduled to investigate Gabrielle later today. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches).

HAZARDS AFFECTING LAND SURF:

SURF: Swells generated by Gabrielle are beginning to reach Bermuda and will build through the weekend. Swells generated by Gabrielle should reach the east coast of the United States from North Carolina northward, along with Atlantic Canada, later this weekend into early next week. These swells are likely to cause life-threatening surf and rip current conditions.

 

Eastern Tropical Atlantic:

>>> A tropical wave over the eastern Atlantic is producing disorganized shower and thunderstorm activity well southwest of the Cabo Verde Islands. Some slow development of this system is possible through the middle to latter part of next week while it moves west-northwestward across the eastern and central tropical Atlantic.
