THE Tornado and Storm Research Organisation (TORRO), based at Oxford Brookes University, collects details of severe local storms in the British Isles.

We are investigating the severe thunderstorms of Sunday, June 19, and especially the intense fall of large hailstones which affected places in North Yorkshire, eg in the Northallerton area.

I would be grateful to hear from any readers who observed the storm, and who can provide details of the size of the hailstones (photographs are welcome), and any resulting damage; also any other storm damage.

Please write to me at the TORRO Thunderstorm Division, PO Box 84 Oxford OX1 4NP, or email me on jonathan.webb@torro.org.uk
