tropical cyclone information statement in effect

Subtropical Storm Josephine - centre is about 300 km southeast of Cape Cod moving northeast (3 p.m. ADT Thursday). This is the 2nd bulletin from the CHC on this storm which is forecast to transform back to a non-tropical low later today while intensifying and bringing up to hurricane-force winds over southern Canadian waters. The centre will track eastward well south of Nova Scotia and Newfoundland. Periods of rain will continue to spread across parts of Nova Scotia today and southeastern Newfoundland later today. Gusty northeast winds will accompany the rain tonight but this weather is primarily associated with a developing front and only indirectly connected to Josephine. This bulletin is geographically set for portions of the Maritimes Marine district slope waters nearest to the track of the storm. A CHC-specific track/intensity forecast is not planned since the storm will be sub-tropical for only a short period before quick transition to frontal system this evening. Another update to this bulletin is planned for Friday morning. Forecaster: Fogarty ### Please continue to monitor alerts issued by the Canadian Hurricane Centre and forecasts issued by Environment Canada.

Safety information

What to do in a tropical cyclone

Three things first, then how little water it takes, and what to do before, during and after. From FEMA’s Ready.gov and the US National Hurricane Center.

For this reportSevere Weather · Canada

  1. Leave if you are told to

    If you live in an evacuation zone and authorities order it, go at once. Water kills most: storm surge, the sea pushed ashore, and flooding rain.

    Ready.gov · NHC
  2. Shelter in an inner room

    Away from windows, on the lowest floor that will not flood. If water rises, go up, never into a closed attic.

    Ready.gov
  3. Stay in when the wind drops

    The calm of the eye can last minutes before the wind returns from the other side.

    Ready.gov · NHC

It takes very little moving water

15cmknock an adult down
30cmcarry away most cars
60cmcarry away SUVs and pick-ups

Moving water. Figures from the US National Weather Service, “Turn Around Don’t Drown”. Person, car and water are drawn to the same scale.

Before, during, after. Here it is “after”.

Before · When a cyclone is forecast

  • Know your evacuation zone

    And the route out of it.

  • Prepare the house

    Bring in outdoor furniture, clear gutters, protect windows.

  • Supplies for several days

    Water, food, medicines, torches, batteries, phone chargers.

  • Help your neighbours

    Especially older people and those who need assistance.

Ready.gov (FEMA)

During · While the storm passes

  • Stay indoors

    Inner room, away from windows.

  • Never into floodwater

    Fifteen centimetres of moving water can knock you down, thirty can carry your car.

  • Keep listening

    Official alerts and local radio.

Ready.gov (FEMA)

After · When the storm has passed

  • Keep away from power lines

    And from anything touching them.

  • Generators outdoors only

    Their fumes kill indoors.

  • Avoid floodwater

    It can carry sewage, chemicals and electricity.

  • Messages, not calls

    Keep lines free for emergencies.

Ready.gov (FEMA)

Questions people ask

What is storm surge?

The sea pushed onto land by the storm’s wind. It is often the greatest threat to life in a tropical cyclone, and can flood far inland. Source: US National Hurricane Center.

Cyclone, hurricane, typhoon: what is the difference?

The same storm with different names by ocean: hurricane in the Atlantic and north-east Pacific, typhoon in the north-west Pacific, cyclone in the Indian Ocean and South Pacific.

Is the calm in the middle the end?

No. It is the eye; the wind returns from the opposite side, often as strong. Stay indoors. Source: Ready.gov (FEMA).
