Understanding warnings
How to read a warning and act on it.
Advisory, watch, warning
| Term | Means | Do |
|---|---|---|
| Advisory | Hazardous conditions are possible for some activities | Be aware; monitor updates |
| Watch | Hazardous conditions are likely across a broad area | Prepare; review your plans |
| Warning | Hazardous conditions are expected or occurring | Take protective action now |
What a warning tells you
Every warning names the hazard, the area affected, when it starts and ends, how severe it is expected to be, and what you should do. The action line is the part that matters most — it is why the warning was issued.
Warnings also describe expected impacts, not just the weather. "Localised flooding of low-lying roads" tells you more than a rainfall total does.
Common misreadings
A warning ending does not mean the hazard has ended. Flooding and landslip continue after the rain stops, and sea state takes time to settle after the wind eases.
No warning does not mean no weather. Ordinary showers and brisk trades sit below warning level and can still disrupt an outdoor plan.
A warning for the tri-island state does not mean every parish sees the same conditions. Read the named areas.
Where warnings come from
The Grenada Meteorological Service is the official source of weather warnings for Grenada, Carriacou and Petite Martinique. Warnings are published on this site and in a structured Common Alerting Protocol feed used by broadcasters, agencies and alerting apps.
During an event, treat the official feed as authoritative over social media reposts, which are often out of date or altered.
