A considerable amount of thunder and quite a lot of lightning has
suddenly appeared due south of me here close to Dorchester. A very
bizarre situation- not a lot on the radar. Very heavy rain just
started. Thunder every 20 seconds or so....

Several rumbles of thunder in the last 5 minutes here at
Warlingham, NE Surrey. (0135Z). Some c-c lightning, distance 2 miles
to S (10 sec). No rain yet. E'ly increased to Force 4.
