[RAC-Bulletin] Hurricane Dorion Update: Environment Canada Issues Second Tropical Cyclone Information Statement


Environment Canada has issued an update on the Tropical Cyclone Information Statement it sent out this morning and it has been included below and posted on the RAC Website at:


As Dorian chugs its way North, it is now clear that the affected areas are those indicated in my earlier bulletin which is also provided below.

As the Hurricane approaches your location please be sure to secure any loose items in your yard that could become projectiles.

Make sure you have food and water for 72 hours.

Make sure you have batteries for all of your lights and radios and fuel for the generator.

If you live in the Maritimes, tonight would be a good time to do that. Drop your antenna if you can, and make sure that you know where your family is going to be during the storm.

Monitor local VHF repeaters in case your assistance is needed and be prepared for a call out from your NGO or Municipality.

If you live in the affected area, please monitor the Hurricane Watch Net that will remain in continuous operation on 14.325 MHz and 7.268 MHz throughout the event.

In Newfoundland and Labrador we will activate a CANWARN net at 9:00pm NL time on Saturday and will relay “on the ground” observations to the Environment Canada Weather office in Gander.

During the next 72 hours, stay safe and out of harms way as much as possible.

Stay tuned to this website and to our social media sites for more information.

For Hurricane Dorian:

The next information statement will be issued by 09:00 pm ADT at:


Hurricane Dorian is accelerating towards Nova Scotia and will make landfall Saturday evening. Extreme winds and Heavy Rain for parts of Atlantic Canada.

Public weather impacts and warnings summary:

A Hurricane Warning is in effect for central and eastern Nova Scotia, and a Hurricane Watch is in effect for southwestern Newfoundland.

Tropical storm watches are in effect for western Nova Scotia, southeastern New Brunswick, Prince Edward Island, the Magdalen Islands and northwestern Newfoundland.

According to the latest forecast guidance, the most likely track projection brings Hurricane Dorian south of the Maritimes on Saturday, passing near or over Halifax, Nova Scotia on Saturday night, and then over the eastern Gulf of St. Lawrence waters or western Newfoundland by Sunday morning.

Severe winds and torrential rain will have major impacts for southeastern New Brunswick, Prince Edward Island, Nova Scotia, Western Newfoundland, and the Quebec Lower North Shore, and the Magdalen Islands. Large waves are expected for the Atlantic coasts of Nova Scotia, Newfoundland and for eastern portions of the Gulf of St. Lawrence. Finally, storm surge, combined with large waves and pounding surf, may give flooding for parts of Nova Scotia, Prince Edward Island, Newfoundland, and the Magdalen Islands.

a. Wind.

Most regions will experience tropical storm force winds of 90 to 110 km/h, beginning over southwestern Nova Scotia Saturday morning, in the afternoon over eastern Nova Scotia, and towards evening for Prince Edward Island, the Magdalen Islands, and southwestern Newfoundland. Near and to the south of the forecast track, winds will reach hurricane force of 120 km/h or more. Behind the storm, there is a possibility of storm to hurricane force northwesterlies. Wind impacts will likely be enhanced by foliage on the trees, causing broken branches and tree falls, resulting in power outages, blocking of roads, and other type of damages.

Hurricane force wind warnings are in effect for Eastern Nova Scotia and Eastern Prince Edward Island. Wind warnings are in effect for Southwestern Nova Scotia, Western Prince Edward Island, and the Magdalen Islands.

b. Rainfall.

Rainfall will be a major factor as torrential rain may lead to flooding. The highest rainfall amounts are expected over Nova Scotia, Prince Edward Island, and the Magdalen Island where 50 to 100 mm are expected. Forecast guidance is also suggesting a swath in excess of 150 mm north and west of Dorian’s track. Some districts have received large quantities of rain last week, and with the soil moisture still very high, excessive runoff may exacerbate the flooding potential. This combined with the severe winds may result in damage due to falling trees.

Rainfall warning for Western Nova Scotia, Western Prince Edward Island, extreme eastern and southern New Brunswick.

c. Surge/Waves.

There will also be rough and pounding surf, especially for parts of Nova Scotia, Newfoundland and the Gulf of St. Lawrence. Waves of 7 to 10 metres will reach the Southwestern Shore of Nova Scotia on Saturday and spread to the Eastern Shore Saturday night. These waves will likely reach southern Newfoundland by Sunday morning with waves nearing 12 metres. Waves of 4 to 7 metres will impact north facing coasts of the Gulf of St. Lawrence. Note that waves will break higher along some of the coastlines, and dangerous rip currents are likely. Please exercise extreme caution.

Storm surge is an issue, mainly for the Atlantic coast of Nova Scotia, the north coast of Prince Edward Island, southwestern Newfoundland, and the Magdalen Islands. Current guidance suggests water levels approaching inundation levels during high tide. However, when combined with rough and pounding surf, there may be flooding and overwash of waves.

Storm surge warnings will be issued for Blanc Sablon, Chevery and Anticosti Island, as well as the Magdalen Islands, overnight.

Marine weather impacts and warnings summary:

Hurricane force wind warnings are in effect for southern and eastern waters of the Maritimes.

As Dorian moves into our waters, it will spread hurricane force southeasterlies near and south of its track, over offshore Canadian waters. As the hurricane moves further into the Maritimes, storm to hurricane force northwesterlies will develop behind it. Waves of 10 to 15 metres are expected south of the storm track, beginning late Saturday over southwestern waters and approaching the south coast of Newfoundland Sunday morning. As the low continues east Sunday into Monday, waves of 4 to 7 metres will develop over eastern waters, and for the southwestern Grand Banks will build to 5 to 10 metres and will diminish to near 5 metres late in the day.

Hurricane force wind warnings are in effect for most Atlantic watern and storm warnings are in effect for most other waters.

Forecasters: March/Mercer/Couturier
