Right now

The most recent data we hold from GDACS arrived 21 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

It is one of only 2 we have recorded within 20 km of this point since 3 September 2026. The last comparable one was on 3 September 2026.

How we know

One source: GDACS. Not yet confirmed by a second, independent source.

Our own score for this event is 60 out of 100.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Computed under scoring rules v4. Rows carrying other versions were judged by different rules and are not directly comparable.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.

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 reportCyclone · China

  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.

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).
