Hay fever sufferers may want to stay indoors this weekend as forecasters warn of a 'pollen bomb' bringing with it some of the highest levels of tree pollen this year.
The warning comes from Kleenex and Allergy UK, who have launched a new 'Pollen Pal' tool, giving a three day pollen count forecast to help hay fever sufferers.
London, Leicester and Nottingham will be among the worst affected, with almost twice the concentration of pollen as will be seen in other 'high pollen' regions.
The Met Office, which produces a regional forecast for the UK says their data suggests a low to medium pollen count for most of the country this weekend.
