DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Tropical Storm Henri was located near latitude 29.5 North, longitude 69.5 West. Henri is moving toward the west near 9 mph (15 km/h). A turn toward the northwest is forecast on Friday, followed by an acceleration toward the north and north-northeast Saturday and Sunday. On the forecast track, the center of Henri will remain well offshore the east coast of the United States over the next couple of days but could approach southeastern New England on Sunday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some strengthening is forecast during the next few days, and Henri is expected to become a hurricane by Friday. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 995 mb (29.39 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Henri should continue to affect Bermuda during the next day or so. Swells are expected to increase across much of the east coast of the U.S. and Atlantic Canada later this week and this weekend. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
