Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected within the warning area within 36 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.

DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the eye of Hurricane Dorian was located near latitude 36.9 North, longitude 72.7 West. Dorian is moving toward the northeast near 24 mph (39 km/h), and this general motion with an additional increase in forward speed is expected through Sunday. On the forecast track, the center of Dorian should move move to the southeast of extreme southeastern New England tonight and Saturday morning, and then across Nova Scotia late Saturday or Saturday night. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Some strengthening is possible during the next 24 hours. After that time, Dorian is forecast to become a post-tropical cyclone with hurricane-force winds Saturday night or Sunday while it is near or over eastern Canada. Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 958 mb (28.29 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will persist for a few more hours in the warning area over the Mid-Atlantic states. Tropical storm conditions are expected in the warning area over portions of extreme southeastern Massachusetts tonight or early Saturday, and in the warning area in Maine Saturday afternoon. Regardless of whether Dorian is a hurricane or a post-tropical cyclone, hurricane conditions are expected in the Hurricane Warning area Saturday or Saturday night, and they are possible in the Hurricane Watch area Saturday or Saturday night. Tropical storm conditions are expected in the Tropical Storm Warning area in Canada by Saturday, and they are possible in the Tropical Storm Watch area Saturday and Saturday night. 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... Salter Path to the North Carolina/Virginia border, including Pamlico and Albemarle Sounds...2 to 4 ft Water levels could begin to rise well in advance of the arrival of strong winds. The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the coast, 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. 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 4 inches. Nova Scotia...3 to 5 inches, isolated 7 inches. New Brunswick and Prince Edward Island...2 to 4 inches Newfoundland...1 to 2 inches This rainfall may cause life-threatening flash floods SURF: Large swells will affect much of the southeastern United States coast from northern Florida through North Carolina during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
