SUMMARY OF 500 PM EDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...41.6N 72.4W ABOUT 100 MI...160 KM NE OF NEW YORK CITY ABOUT 20 MI...35 KM SE OF HARTFORD CONNECTICUT MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 7 MPH...11 KM/H MINIMUM CENTRAL PRESSURE...997 MB...29.44 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: All coastal Tropical Storm Warnings have been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Tropical Storm Henri was located by surface observations and and NOAA Doppler weather radars near latitude 41.6 North, longitude 72.4 West. Henri is moving toward the west-northwest near 7 mph (11 km/h), and this general motion with a decrease in forward speed is expected through early Monday morning. A slow turn toward the north is expected Monday morning, followed by a motion toward the east-northeast Monday afternoon. On the forecast track, Henri is expected to slow down further and possibly stall near the Connecticut-New York border tonight, then move across northern Connecticut or southern Massachusetts by Monday afternoon. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Additional weakening is forecast during the next couple of days, and Henri is expected to become a tropical depression this evening and degenerate into a post-tropical remnant low by Monday afternoon. Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center, mainly over Long Island Sound. A sustained wind of 29 mph (47 km/h) and a gust to 42 mph (68 km/h) were recently measured by a private weather station at Orient Point on eastern Long Island. The estimated minimum central pressure based on nearby surface observations is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Henri can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and on the web at www.hurricanes.gov/graphics_at3.shtml?key_messages. RAINFALL: Henri is expected to produce storm total rainfall of 3 to 6 inches with locally higher amounts expected over portions of Long Island, New England, southeast New York, New Jersey, and northeast Pennsylvania Sunday into Monday. Isolated maximum totals of 10 to 12 inches are possible across northern New Jersey into southern New York. Heavy rainfall from Henri will continue to result in considerable flash, urban, and small stream flooding, along with the potential for additional minor to isolated moderate river flooding. For the latest rainfall reports and wind gusts associated with Henri at the following link: www.wpc.ncep.noaa.gov/discussions/nfdscc3.html WIND: Wind gusts to tropical storm force are possible along coastal areas of Connecticut and northern Long Island during the next few hours. SURF: Swells are expected to continue across much of the east coast of the U.S. and Atlantic Canada today and continue into Monday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Storm Henri Public Advisory Number 27A

2021-08-22 20:10:29| National Hurricane Center (Atlantic)

Issued at 200 PM EDT Sun Aug 22 2021 000 WTNT33 KNHC 221809 CCA TCPAT3 BULLETIN Tropical Storm Henri Intermediate Advisory Number 27A...Corrected NWS National Hurricane Center Miami FL AL082021 200 PM EDT Sun Aug 22 2021 Corrected initial latitude and distance to reference points in summary block. ...HENRI SLOWS DOWN OVER SOUTHWESTERN RHODE ISLAND... ...STRONG GUSTY WINDS AND FLOODING RAINFALL CONTINUE ACROSS PORTIONS OF THE NORTHEASTERN UNITED STATES... SUMMARY OF 200 PM EDT...1800 UTC...INFORMATION ---------------------------------------------- LOCATION...41.4N 71.8W ABOUT 5 MI...5 KM N OF WESTERLY RHODE ISLAND ABOUT 35 MI...55 KM SW OF PROVIDENCE RHODE ISLAND MAXIMUM SUSTAINED WINDS...50 MPH...80 KM/H PRESENT MOVEMENT...NW OR 325 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...991 MB...29.26 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: All Storm Surge Warnings have been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * East Rockaway Inlet New York to Chatham Massachusetts, including Long Island * Block Island, Nantucket and Martha's Vineyard A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests elsewhere in the northeastern U.S. should monitor the progress of Henri. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Tropical Storm Henri was located by surface observations and and NOAA Doppler weather radars near latitude 41.4 North, longitude 71.8 West. Henri is now moving toward the northwest near 9 mph (15 km/h). A northwestward motion with a decrease in forward speed is expected this afternoon. The center of Henri is currently located inland over southwestern Rhode Island. On the forecast track, Henri is expected to slow down further and possibly stall near the Connecticut-New York border tonight, with an east-northeastward motion across northern Connecticut and southern Massachusetts on expected on Monday. Data from Doppler radars and surface observations indicate that maximum sustained winds have decreased to near 50 mph (80 km/h) with higher gusts. Rapid weakening is expected now that Henri has moved inland over southern New England. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. The latest minimum central pressure estimated from nearby surface observations is 991 mb (29.26 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Henri can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and on the web at www.hurricanes.gov/graphics_at3.shtml?key_messages. RAINFALL: Henri is expected to produce rainfall amounts of 3 to 6 inches over portions of Long Island, New England, southeast New York, New Jersey, and northeast Pennsylvania Sunday into Monday, with isolated maximum totals near 12 inches. Heavy rainfall from Henri may result in considerable flash, urban, and small stream flooding, along with the potential for widespread minor to isolated moderate river flooding. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... South shore of Long Island from East Rockaway Inlet, NY to Montauk Point, NY...1-2 ft North shore of Long Island from Flushing, NY to Montauk Point, NY including Long Island Sound...1-2 ft Flushing, NY to Merrimack River, MA including Narragansett Bay, Buzzards Bay, Vineyard Sound, Nantucket Sound, and Cape Cod Bay...1-2 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Tropical storm conditions are expected to continue in the tropical storm warning area into tonight. TORNADOES: The risk for a tornado or two continues today across parts of southern New England. SURF: Swells generated by Henri should diminish around Bermuda later today. Swells are expected to increase across much of the east coast of the U.S. and Atlantic Canada today and continue into Monday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests elsewhere in the northeastern U.S. should monitor the progress of Henri. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Tropical Storm Henri was located by an Air Force Reserve reconnaissance aircraft and NOAA Doppler weather radars near latitude 41.1 North, longitude 71.6 West. Henri is moving toward the north-northwest near 12 mph (19 km/h). A north-northwestward motion with a decrease in forward speed is expected for the next few hours, followed by a turn toward the northwest this afternoon. The center of Henri is currently passing near Block Island and on the forecast track the center is expected to make landfall in Rhode Island by early afternoon. Henri is forecast to slow down and possibly stall near the Connecticut-New York border tonight, followed by an east-northeastward motion across northern Connecticut and southern Massachusetts on Monday. Data from the aircraft, Doppler radars, and surface observations indicate that maximum sustained winds have decreased to near 60 mph (95 km/h) with higher gusts. Little change in strength is expected until landfall occurs, followed by rapid weakening after Henri moves inland over southern New England.
