DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Isaac was located near latitude 37.1 North, longitude 54.1 West. Isaac is moving toward the east near 12 mph (19 km/h) and a general eastward to east-northeastward motion at a slightly faster speed is anticipated over the next several days. Recent satellite wind data indicates that maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some strengthening is forecast during the next couple of days and Isaac could be near hurricane intensity by the end of the week. Tropical-storm-force winds extend outward up to 220 miles (350 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac and a large wind fetch from a deep-layer trough are affecting portions of the coast of Bermuda and 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. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Papin
