Environment Canada issues Tropical Cyclone statement for Moncton, Southeast NB

Following the forming of Tropical Depression Six late Sunday afternoon, Environment Canada has issued an updated information statement for much of New Brunswick on Tropical Storm Erin.

Tropical Storm Erin is currently meandering off the Carolina coast but will begin tracking northeastward toward the Maritimes later today. Erin is expected to transition to a post-tropical storm well before it reaches the Atlantic coast of Nova Scotia early Friday morning. Erin will bring heavy rain to much of the region beginning Thursday and gusty winds with its passage Thursday night into Friday.

1. Summary of basic information at 03:00 a.m. ADT.

Location: Near 32.4 North 72.2 West.

About distance 445 kilometres southeast of Cape Hatteras NC.

Maximum sustained winds: 65 kilometres per hour.

Present movement: West at 6 kilometres per hour.

Minimum central pressure: 1005 millibars.

2. Public weather impacts and warnings summary.

Tropical Storm Erin is expected to transition to a post-tropical system by the time it enters Canadian waters on Thursday. Rain associated with a trough of low pressure approaching from the west will spread over the western Maritimes early Thursday morning. As Erin approaches later on Thursday, some of its moisture will feed into this trough and likely enhance the rain intensity associated with it. The heavier rain and strongest winds associated directly with post-tropical Erin should reach the Atlantic coast of Nova Scotia later Thursday evening.

a. Wind.

  • Some gusty winds will likely accompany post-tropical Erin, especially to those areas just to the right of its track early Friday morning. At this time it is not expected that these winds will reach warning criteria (i.e. gusts to 90 km/h or higher), but could still be strong enough to cause isolated power outages and minor damage, especially given that trees are still in full leaf.

b. Rainfall.

  • The combination of Post-Tropical Erin and its interaction with the trough of low pressure crossing the region on Thursday will combine to produce significant rainfall. Rainfall will likely meet or exceed warning criteria (50 mm or more in 24 hours) in parts of the Maritimes, especially those areas just north and west of Erin’s track. Some isolated locations in these areas could possibly see total rainfall amounts in excess of 100 mm before the rain ends later Friday morning

c. Surge/Waves.

  • At this time, significant storm surge and coastal impacts from high waves are not expected. However, some higher than normal water levels and high surf are possible near and to the right of the Erin’s track where it is expected to cross the Atlantic Coast of Nova Scotia on Friday.

3. Marine weather impacts and warnings summary.

  • Gale warnings have been issued for the southwestern Maritimes marine waters, where gale force southerlies up to 40 knots are expected by Thursday evening. These gale warnings will likely be extended to adjacent marine areas for Friday near and along Erin’s path through Canadian waters.Forecaster(s): Borgel
