Overview

Hurricane Isaias is continually exceeding expectations for strength. There is a large amount of uncertainty beyond two days regarding both track and intensity. Operators are encouraged to check the National Hurricane Center frequently for the most up-to-date projectons.

NBAA Air Traffic Services encourages operators who are planning to travel in to affected regions to contact their FBOs and local authorities to determine what services will be available, as well as top identify off-airport issues, such as local transportation and infrastructure.

Update from the National Hurricane Center

According to the National Hurricane Center’s Advisory #15, issued at 2100z:

At 5 p.m. EDT (2100 UTC), the center of Hurricane Isaias was located by satellite imagery and Bahamas radar data near latitude 22.6 North, longitude 75.7 West. Isaias is moving toward the northwest near 15 mph (24 km/h), and a general northwestward motion with some decrease in forward speed is expected for the next day or so, followed by a turn toward the north-northwest by late Sunday. On the forecast track, the center of Isaias will continue to move near
or over the Southeastern Bahamas this afternoon and evening. Isaias is forecast to be near the Central Bahamas tonight, and move near or over the Northwestern Bahamas Saturday and near the east coast of the Florida peninsula Saturday afternoon through Sunday.

Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Strengthening is expected later tonight and early Saturday, and Isaias is forecast to remain a hurricane for the next couple of days.

Hurricane-force winds extend outward up to 35 miles (55 km) from thecenter and tropical-storm-force winds extend outward up to 175 miles (280 km). A private weather observing station at Pitts Town Point, Bahamas, recently reported a sustained wind of 37 mph (59 km/h).

The estimated minimum central pressure is 991 mb (29.27 inches).
