It may have been a glorious day today with some great spring sunshine but air pollution across Yorkshire is said to be ‘very high.’
The warning has been put out by the Department for Environment, Food and Rural Affairs.
When this happens people with lung or heart problems and older people should avoid strenuous physical activity.
People with asthma may find they need to use their inhalers more often.
Huddersfield weather expert Paul Stevens said our area was getting a double whammy of pollution with the high pressure now over us acting as a cap which is trapping the pollution.
A slight easterly drift has also brought pollution here from both Europe and neighbouring towns and cities such as Leeds.
And it will be bittersweet this week with the high pressure staying which will mean the pollution levels are also expected to remain very high.
Paul said: “This will go on for several days, probably over next weekend and possibly longer still – the pollution can’t go anywhere until the winds pick up again. The last time this happened was last summer but we belch out pollution all year round. People who have asthma may find it a struggle to go out at times like this.”
The different Government ratings for air pollution are low, moderate, high and very high.
