What happened
A large plume of Saharan dust has moved across the eastern Caribbean and is now sitting over Grenada. Expect hazy skies, reduced visibility, and warm, sticky conditions through Thursday before it begins to clear.
Why it matters
Dust degrades air quality. For most people it means itchy eyes and a scratchy throat. For people with asthma, allergies, or heart conditions, it can be more serious — symptoms can flare without much warning.
Who is affected
Everyone outdoors, but especially children, older people, outdoor workers, and anyone with respiratory conditions. Fishers and sailors should also note the reduced visibility at sea.
What to do
- Keep windows closed during the haziest part of the day.
- Have asthma medication and inhalers close to hand.
- Limit hard exercise outdoors at midday.
- Water young plants early; the strong sun will dry soil quickly.
The dust should ease by the weekend, with a better chance of refreshing showers on Saturday.
