Dear All

Picnic-ing with friends this afternoon watching cricket, and through the
trees came a low-level swirl, travelling probably at about 10-15mph with
what I would guess 30mph winds travelling round it. Is this a land devil
or
something like this? Not really familiar with the terminology - certainly
had the strength to take one or two leaves off the trees as it passed
through the cricket pitch, where the cricketers stood around looking
mightily confused.

Any thoughts?
Richard

Either a land devil , or a strong thermal
