A pollen 'bomb' could cause misery for hay fever sufferers this week, according to new forecasts.
Elevated pollen counts from the weekend now look set to last for most of the week, as the first weeks of spring combine with mild weather conditions to create a perfect storm of airborne tree particles.
Allergy sufferers are likely to be affected in particular by particles from birch, plane, willow, ash and little oak trees, with April also being peak season for pleospora fungal spores.
