| If you zoom in to the map on the National Data Buoy Center page: https://www.ndbc.noaa.gov/ You can seem some of them. I believe the one the NHC mentions is this one: https://www.ndbc.noaa.gov/station_page.php?station=44008 It's pulling away from that one. It wasn't as close to that one as it is going to be this one: https://www.ndbc.noaa.gov/station_page.php?station=44011 Where the wind is climbing and the pressure dropping. On the buoy page for a station look at the list of "Previous observations" and under that table heading you will see little chart icons. Click the chart icon for a chart of recent obs.

DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Dorian was located near latitude 40.9 North, longitude 67.0 West. Dorian is moving toward the northeast near 25 mph (41 km/h), and this general motion is expected through Sunday. On the forecast track, the center of Dorian should pass to the southeast of extreme southeastern New England this morning, and then move across Nova Scotia and Newfoundland later today and tonight. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Some slight weakening is forecast, but Dorian is expected to move over Nova Scotia with hurricane-force winds. Thereafter, Dorian is forecast to become a powerful post-tropical cyclone over eastern Canada by tonight or early Sunday. Hurricane-force winds extend outward up to 105 miles (165 km) from the center, and tropical-storm-force winds extend outward up to 310 miles (500 km). A NOAA buoy at Nantucket Shoals, Massachusetts, recently reported a sustained wind of 64 mph (104 km/h) and a gust of 80 mph (129 km/h). A Weatherflow station at Sagamore Beach, Massachusetts, recently reported sustained winds of 40 mph (64 km/h) and a gust of 51 mph (82 km/h). The estimated minimum central pressure is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to continue in the warning area over portions of extreme southeastern Massachusetts during the next few hours. These conditions should spread into the warning area in Maine by this afternoon. Regardless of whether Dorian is a hurricane or a post-tropical cyclone, hurricane conditions are expected in the Hurricane Warning area in Nova Scotia and Newfoundland beginning later today, and they are possible in the Hurricane Watch area by tonight. Tropical storm conditions are expected in the Tropical Storm Warning area in eastern Canada later today and tonight. STORM SURGE: Storm Surge is likely in the Gulf of St. Lawrence, the Southwest Coast of Newfoundland, and Eastern Nova Scotia. RAINFALL: Dorian is expected to produce the following rainfall totals through Saturday: Extreme Southeastern New England and far eastern Maine...1 to 3 inches. Nova Scotia...3 to 5 inches, isolated 7 inches. New Brunswick and Prince Edward Island...2 to 4 inches Newfoundland and far eastern Quebec...1 to 2 inches This rainfall may cause life-threatening flash floods SURF: Large swells are increasing along the coast in Atlantic Canada, and they will continue to affect that area during the next few days. Swells along the mid-Atlantic and New England coasts of the U.S. will continue for a couple of more days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Beven |
