Wind has changed the surface of the park and neighbourhood overnight, leaving large piles of torn leaves, knocking down branches, ripping coverings off parked motorcycles and bending 'for rent' signs on their axes. Whistles and howls echo through the streets and across the downs, joined by the sirens of ambulances and fire trucks. On local radio this morning there was mention of wifi and phone service cuts. This is London in the aftermath of Storm Isha, which has swept across the southeast overnight. Its long arm is dramatically visible in the satellite image I captured today – curving over France, Germany and the continent, and spiralling toward Sweden and Norway.
