What the source measured
GDACS reported: Tropical Cyclone SIMON-26 · Hurricane/Typhoon > 74 mph (maximum wind speed of 231 km/h)
Urban PEI: 6,562 within a heuristic 300 km radius; not unique people.
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 v5. 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.

Cascade risks
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 · Mexico
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 · NHCShelter 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.govStay 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
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).
