Air pollution levels in some parts of the Central region have been the highest in the country today, as a combination of weather factors came together to create an unhealthy haze.
One of those factors was a storm in the Sahara desert thousands of miles away which has sent dust particles high into the atmosphere, which are now falling as sand and grit across the country.
It's been causing real problems for people with existing medical conditions, and those who have heart or lung problems are being urged to avoid strenuous activity.
