Weather expert offers his opinion

What is claimed to be the first expert witness service specifically in the field of weather and meteorological forecasting has been set up.

The service was founded by Norman Lynagh, a Met Office-trained meteorologist and weather forecaster, who worked for London marine consultant Noble Denton's weather section for 20 years. The section was first approached to provide a witness service 10 years ago.

He said it was a response to the increasing number of civil and criminal cases that require information about the weather. Road accidents, major marine disasters and insurance-related cases often required accurate information about weather conditions or the responsibility of organisations accurately to predict weather, he added.

The Buckinghamshire-based Norman Lynagh Weather Consultancy says it can provide worldwide weather information.
