Issued at 1100 AM AST Wed Aug 18 2021 000 WTNT33 KNHC 181435 TCPAT3 BULLETIN Tropical Storm Henri Advisory Number 11 NWS National Hurricane Center Miami FL AL082021 1100 AM AST Wed Aug 18 2021 ...HENRI HOLDING STEADY IN STRENGTH OVER THE WESTERN ATLANTIC... SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...30.0N 66.6W ABOUT 190 MI...310 KM SW OF BERMUDA ABOUT 795 MI...1280 KM SSE OF NANTUCKET MASSACHUSETTS MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...W OR 260 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...998 MB...29.47 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Henri was located near latitude 30.0 North, longitude 66.6 West. Henri is moving toward the west near 8 mph (13 km/h) and this motion is expected to continue for another day or so. A turn to the north is expected on Friday with that motion continuing into the weekend. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Little change in strength is forecast during the next couple of days, but Henri is expected to become a hurricane by the weekend. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 998 mb (29.47 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. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Cangialosi
