Why April's showers could mean a very sneezy summer The showers have helped grass to grow well, according to the Met Office. It says that, if the weather improves as expected, the grass will dry, leading to a huge release of pollen during hay fever season. To combat it, the Met Office has announced a new pollen count application for mobile phones, which uses social media to tell people where the worst areas are. By entering details of where they are suffering, it is hoped Twitter users will build a picture of what triggers the condition, as well as helping fellow sufferers to steer clear of particularly high pollen counts. Patrick Sachon, the health business manager at the Met Office, said: "The wet weather is definitely helping the grass grow so if we have dry weather in May and June it would mean a high grass pollen count and grass pollen affects 95 per cent of sufferers." The forecasters also said there could be a high pollen count for the Jubilee weekend in June and throughout the Olympics. Last month's showers have so far shown little sign of abating. More than 80 properties have already been hit by floods and yesterday a man who drowned in a swollen river in Compton Wood, Hampshire, was named as Jonathan Gammon, a 52-year-old tribunal judge from Teddington, west London. He died with his dog Gabby after their car was swept from a ford. His 54-year-old wife, Priscilla, escaped. The Environment Agency has now issued more than 33 flood warnings,
