Interests in the northeastern U.S. and Atlantic Canada should monitor the progress of Henri. Watches will likely be required for a portion of this area early Friday. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Henri was located near latitude 29.8 North, longitude 72.3 West. Henri is moving toward the west-northwest near 8 mph (13 km/h). A sharp turn to the northwest and north is anticipated on Friday, followed by an acceleration to the north and north-northeast on Saturday and Sunday. On the forecast track, the center of Henri will remain well offshore of the east coast of the United States over the next couple of days, but it is forecast to be near or over southern New England on Sunday and Monday. Maximum sustained winds remain near 65 mph (100 km/h) with higher gusts. Little change in strength is expected during the next 12 hours, but Henri is forecast to intensify into a hurricane by Friday night with additional strengthening expected this weekend. Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Henri may produce rainfall amounts of 2 to 5 inches over southeastern New England Sunday into Monday, with isolated maximum totals near 8 inches. Heavy rainfall from Henri may result in areas of flash, urban, and small stream flooding. 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 on Friday and into the weekend. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
