SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Bermuda A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 24 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Henri was located near latitude 30.0 North, longitude 65.1 West. Henri is moving toward the west-southwest near 8 mph (13 km/h). A gradual turn to the west with a faster forward motion is expected over the next 12 to 24 hours, followed by an additional turn to the west-northwest and northwest by late Thursday. Maximum sustained winds remain near 65 mph (100 km/h) with higher gusts. Some additional strengthening is possible tonight, followed by little change in strength through Thursday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible tonight across Bermuda and the nearby waters, particularly to the south of the island. SURF: Swells generated by Henri are expected to affect Bermuda during the next day or so. Swells could increase along the southeast and mid-Atlantic U.S. coasts by the end of the week. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
