1. Dorian will continue to have significant impacts in portions of eastern Canada today. Dangerous storm surge impacts are likely in portions of the Gulf of St. Lawrence, southwestern Newfoundland and eastern Nova Scotia. Hurricane-force winds are still occurring in portions of eastern Nova Scotia and are spreading into western Newfoundland. Refer to information from the Canadian Hurricane Centre for more information on these hazards.

WHAT'S NEW:

The Canadian Hurricane Center has discontinued all warnings for Nova Scotia west of Ecum Secum on the southern coast and west of Brule along the northern coast. All warnings have also been discontinued for New Brunswick. The Hurricane Watch for Prince Edward Island has also been discontinued.

SUMMARY OF ALERTS:

A Hurricane Warning is in effect for...
- Eastern Nova Scotia from Ecum Secum to Brule
- Western Newfoundland from Indian Harbour to Hawke's Bay

A Hurricane Watch is in effect for...
- Magdalen Islands

A Tropical Storm Warning is in effect for...
- Prince Edward Island
- Magdalen Islands
- Stone's Cove to Indian Harbour
- Hawke's Bay to Fogo Island
- Mutton Bay to Mary's Harbour

A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area.

A Tropical Storm Warning means that tropical storm conditions are expected within the warning area.

A Hurricane Watch means that hurricane conditions are possible within the watch area. For storm information specific to your area, please monitor products issued by your national meteorological service.

WIND: [TOP] Tropical storm and hurricane conditions are still occuring over portions of Nova Scotia. Hurricane conditions are also expected elsewhere in the Hurricane Warning area in Newfoundland today. Hurricane conditions are also possible in the Hurricane Watch area through this morning. Tropical storm conditions are expected in the Tropical Storm Warning area today.

STORM SURGE: [TOP] A dangerous storm surge is likely in the Gulf of St. Lawrence, the Southwest Coast of Newfoundland, and Eastern Nova Scotia.

RAINFALL: [TOP] Dorian is expected to produce the following rainfall totals through tonight:

New Brunswick...2 to 4 inches Newfoundland and far eastern Quebec...1 to 2 inches

These rainfall amounts could result in flash flooding.

SURF: [TOP] Large swells are affecting the coast of 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 another day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

At 500 AM AST (0900 UTC), the center of Post-Tropical Cyclone Dorian was located near latitude 48.5 North, longitude 61.1 West. The post-tropical cyclone is moving toward the north-northeast near 26 mph (43 km/h), and this general motion with a turn to the northeast is expected during the next couple of days. On this track, Dorian will be moving near or over western Newfoundland later today and then enter the North Atlantic this evening.

Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. These winds are occurring mainly over water. The post- tropical cyclone is forecast to drop below hurricane strength after passing Newfoundland later today.

Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 345 miles (555 km). A sustained wind of 62 mph (100 km/h) with a gust to 79 mph (128 km/h) was recently reported at Heath Point on Anticosti Island. A wind gust to 69 mph (109 km/h) was recently observed at North Mountain in Nova Scotia.

The estimated minimum central pressure is 960 mb (28.35 inches).

The center of Post-Tropical Cyclone Dorian passed very near the Magdalen Islands around 0600 UTC, and is now between the west coast of Newfoundland and Anticosti Island. Earlier ASCAT data indicated that the wind field remains quite large, but the peak winds have decreased since yesterday. Therefore, the initial intensity has been set at 70 kt. Dorian is expected to remain a powerful storm through this afternoon, but the global models show steady weakening after the center moves northeast of Newfoundland tonight.

The cyclone is moving north-northeastward or 025/23 kt. Dorian should continue north-northeastward today, then turn east- northeastward over the North Atlantic as it remains embedded within the mid-latitude westerlies. The dynamical model guidance continues to be in good agreement, and the new official track is essentially an update of the previous advisory. The post-tropical cyclone should should be absorbed by another extratropical low over the North Atlantic in 2 to 3 days. The Ocean Prediction Center (OPC) once again provided guidance on the forecast intensity and wind radii.

The National Hurricane Center will continue to issue advisories on Dorian as a post-tropical cyclone until the threat to eastern Canada has ended.

The center of Post-Tropical Cyclone Dorian is now over the northeastern Gulf of St. Lawrence. There are no observations from the area southeast of the center where the strongest winds are likely to be. However, the winds at the nearby land stations are gradually decreasing. Based on this and some decay in the cloud pattern, the initial intensity is lowered to 65 kt. The global models forecast Dorian to steadily weaken until the cyclone is absorbed by another large extratropical low to its north between 36-48 h. The Ocean Prediction Center (OPC) once again provided guidance on the forecast intensity and wind radii.

The cyclone is now moving northeastward or 035/22 kt. This general motion should continue through this evening, with the center of Dorian passing near or over northwestern Newfoundland or eastern Labrador on its way into the far north Atlantic. This should be followed by an east-northeastward motion for the remainder of the cyclone's life. The dynamical model guidance continues to be in good agreement, and the new official track is again an update of the previous advisory.

The National Hurricane Center will continue to issue advisories on Dorian as a post-tropical cyclone until the threat to eastern Canada has ended.
