Isaac is moving toward the east near 16 mph (26 km/h). A gradual turn to the east-northeast is expected with a slight decrease in forward speed over the next day or so.

Some slight additional strengthening is expected tonight or Saturday morning followed by gradual weakening through early next week. Isaac is expected to be a post-tropical cyclone on Monday.

The estimated minimum central pressure is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac and a large wind fetch from a deep-layer trough could spread into the Azores by this weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
